School me on overdrive transmissions for a RB - 04/20/12 09:54 PM
which OD trans would be best behind a 500" RB in a E-body, street driven only car. the current combo is 600 HP.
gearvendors is out, so please don't go there.

Passon gearset in an 833 case, until he is in production of his 5 speed its the next best thing because you dont have to cut/chop anything. Tim

I'm in the same boat... already revamping the cam selection and distributor curving to match my 505 with an overdrive 5 speed. Renovation started last week... next is the wait for the trans... It will be worth it! Patiently waiting Jamie...

4L80E with an Ultrabell. It's a very stout transmission and well-known in the HP aftermarket. Standalone controllers have been on the market for years.

I covered all the known options in my B-body book. Bottom line is that it depends if you're willing to cut the floor or not. If you're willing to cut the floor and the tranny crossmember then the options go way up.

Re: School me on overdrive transmissions for a RB - 04/21/12 12:58 AM
this needs to be an auto trans. i'm not willing to cut the floor up on a 70 E body convertible. changing the crossmember is no big deal though.
does the 4L80 fit without cutting the floor?

Re: School me on overdrive transmissions for a RB - 04/21/12 03:56 AM
I don't think so. I've seen pictures of a handful of swaps and in every case the person needed to cut the floor to remove the tranny crossmember. That crossmember is a big deal in a Mopar since that is where the torsion bar anchors are. Some guys go with a coil over suspension to get rid of the torsion bars, other guys build a new crossmember.
I did see some posts by a guy who said that he did it without cutting the floor, but I think what he did was lower the engine and/or put the tranny in at a weird angle.
Eberg just did this swap in Mopar Action. Check out the pictures in the back issues. They cut the floor and did a fair amount of fab work.
The Keisler OD auto is supposed to fit without any cutting. I'm sure there are some guys on the board with that kit installed. Maybe someone will weigh in with some feedback.

Then really your only option is a GM 700R4. The Keisler auto is based on the GM 4l60-e, which is the electronic version of the 700R4. It will take a well built 700R4/4l60-e to take 600hp but it can be done.

4l80E will need the floor cut.
GV is a good option here. Why is it out of the picture(just curious)? I do a lot of GV conversions and currently finishing one up on a 70 Charger R/T. Everyone who I have installed one of these units on has been VERY happy. They are trouble free, and can handle a fair amount of power. B/E cars require very little floor massaging(no cutting), but admittedly I have never done one on a convert so I cant attest to the fitment there.
Otherwise, your options are very limited if no floor cutting is mandatory. What I gave done on some that the floor needed cutting, I simply cut a clean section out and fabbed another replacement floor piece that raises the roof on the floorboards, so to speak. The piece is cut cleany out and can easily be buttwelded back in and with a bit of bodywork can be made to look 100% perfect when done.
Let me know if you want any photos of the installation in the Charger. Car is just about ready to get off the lift.

As mentioned, Keisler's 4L60 will basically bolt in, but 600 ft/lbs is max-max.
6-speed version of 4L80 (TCI 6X) is awesome beyond belief, but a lot of hacking required; as Andy mentioned, I wrote it all up in macro detail.
Both of these keep propshaft / u-joint angles better than stock, and there's no unsupported cantilevered housing dangling out there as with GV. And the programability, converter lock, etc., places them in a class alone.

Dan,
This is something less popular on Mopars, but maybe try talking to these two 200R4 specialists:
Lonnie Diers at Extreme Automatics
Or
Dave Husek at TURBO BUICK PERFORMANCE
The 200R4 has a lot of following in Turbo Buick circles, and can be built to take a lot. Built right it can be much stronger than any 700R4 and its derivatives (4L60E).
It's a very compact transmission. If there's an adapter plate for BBM to GM transmissions, then I am pretty sure it can be done with no floor hacking.
It would probably be much cheaper than Keisler.
Good luck,
Ran

The 700R4 guys say theirs is better than the 200-4R. The 200-4R guys say theirs is better than the 700R4. What I've read makes it sound like they both start crapping out at around the same hp levels.

Yeah... about 300hp and a little bit of traction

1wildRT put a 5/18 in an ebody vert without cutting the floor , there are pictures somewhere. the only real issue is controlling od and possibly lockup , can be done with pressure and vac switch with the mechanical gov version , but the electronic gov trans is a little better to deal with.
i don't think there is a stand alone controller for one yet , if there is it would be cheaper to buy a Z06 corvette ..

before you get into an ultra bell to put a chev tranny in----consider the 618---it is quite strong and lives behind a cummins or V10 motor and they can be built up for those 1000+ hp trucks--before anyone starts whining about the build cost--the chev units will have to be built too-the early ones are hydraulic valve body and simple to work with---bob

Re: School me on overdrive transmissions for a RB - 04/22/12 02:58 PM
You can usa a 518, no floor cutting. Check here at cuda-challnger:
http://www.cuda-challenger.com/cc/index.php?topic=23678.0In the Moparts archive is a member you put it behind a big block with the ultra bell, don't have a link off hand.
For the trans mount, US Car Tool told me they make it so you can get it from them.
Member Whoosewhatzit, (something like that) was thinking of making a electronic controller for the 96 and up 518s, otherwise you need a 94-95 (best for lock up convertor), or real earlier non lockup (handles more HP, but will need a few mods). You then need a few more items like someone else said for the OD and such.

Stock GM trannys are as you describe. But there has been a lot of development from the aftermarket.
I am not aware of anyone claiming built 700R4 types can handle more than 200R4.
4L80E (and the TCI 6 pseed) are beefy but huge, so they are out of the question.
I am all for keeping cars as Mopar as possible. But sometimes the 518/618 solution does not fit the vehicle. Mopar chose to take a 727 and stick an OD unit on the end of it. The GM trannys have more compact dimensions because they are designed differently.

Yep. I take a built 200-4R over a built 727 with a GV unit any day of the week. I think some here would be shocked at the amount of HP the 200 can take when built properly. At a much reduced weight to boot. Win, win.

Re: School me on overdrive transmissions for a RB - 04/23/12 12:54 AM
Not many automatic options unless you cut the torsen bar crossmember out of the trans tunnel?
Keisler claims no cutting required for their kit, so it might work? Their stage 3 kit is "rated" at 650 lb-ft.

Re: School me on overdrive transmissions for a RB - 04/23/12 12:57 AM
GM knows a good thing when they see it---Gm and ford have been paying royalties to chrysler since the 60,s for developing technology(727) in automatic transmissions----yes i know when the diesel came out chrysler bought turbo 400 torque converters from gm---but alas allison even used the turbo 400--- (it was easier to just buy it instead of going into developement)-----can any of you gm/chrysler technophobs tell me if chrysler has been paying royalties to GM for their transmission innovations?---if i remember the article right 17 manufacturers world wide have paid royalties to chrysler (727) for the use----bob

Re: School me on overdrive transmissions for a RB - 04/23/12 03:20 AM
Being an Olds guy as well, I know that a lot of people use the 200-4R in their Cutlasses behind 455s with great success. An Olds 455 is easily in the 500+ lbs./ft. community. It's all in how it's put together. As mentioned earlier, check with the Turbo Buick guys. They are running sub-11's in 3500 lb. Regals with these trannies.
Another plus to a 200-4R over the 700R4 is the gear spread. The drop from first to second is closer, being better for a big-block, with a slightly better O.D. gear.

The Man since I was a little boy is Art Carr. He, however, cashed in on his name and now if you want an Art Carr transmission you go to:
http://cpttransmission.com/where you can buy his version of the 200. I've been looking at one to go behind a 455 in my '65 Cutlass S in place of the Super Turbine 300. Looks encouraging. Remember that you have to have resistance at the other end to make a component actually see the torque.
Also, unless the 'vert is going to get massive frame reinforcements, it'll be twisted into pretzel shape long before any real driveline damage is done. I say this based on seeing twisted bigblock E-bodies at the drag strip back in the day. So I believe the emphasis on strength of the transmission is more a talking point than a real need.
So, the bolt in Keisler kit, which I believe uses a 4L65E, is a winner. The runner up goes to a make-it-fit-yourself 200-4R.

Dan call Pat at SMR in canada. He can custom build ya a 518 and you will have to have an adapter kit to bolt it to a big block.
Pat is good people, very easy to deal with and beats on his auto overdrives in his own race Dakota. He will go over any details you might deal with and help ya right along.

they used it before they developed their own----it seems to be common knowledge down at the torque converter shop i was told thats why mopar picked it up--because it was previously used and proven and was cheaper for mopar to buy instead of going into developement on their own

A bit off topic, but the new book by Andy F had an interesting idea on chassis stiffening, of using two floor pans? I never heard of anyone doing that, but it sounds like a good idea (along with subframe connectors) in a convertible?
Posted By: Fury Fan
Re: School me on overdrive transmissions for a RB - 04/24/12 01:05 PM
That is an interesting idea, some demo derby guys double-up door and fender skins like that.
I'm not sure what to think of doing that to a 'keeper' car unless it never saw rain or temperature swings / condensation.

Allison was a GM subsidiary from 1928 until 2007, when it went private. The TH-400 converter was in the corporate family.

Yes, It is a Gear Vendors unit. Looks like they came up with a shortened version of the adapter housing with matching parts. If it fits as they say, its a nice deal. Never saw one.

It is a GV. It uses the shorter truck 727. When I finally pull the trigger for OD in my 66 C-body that's the choice. I already have the trans from a 4x4 that used a divorced t-case.

Thanx. I haven't been back since. The best that day was a 13.92. 60 ft was a no traction 2.23. I've gone from a 2.76 SG to a 3.23 SG and I need to put some real tires on it. 12.99 is the goal. It weighs 4800.... Yeah I know

When searching for parts to build your trans, just remember it's a 200-4R, not a 200R4. A common mistake that might make parts searches a lil more tough.

first of all, many thanks to everyone for the info. it's very much appreciated.
trying to update these older Mopar musclecars to make them more highway friendly and reliable is expensive, to say the least. it's probably one of the many reasons Mopars are only a small fraction of the overall musclecar scene as a whole.
i got a quote from Keisler to do the complete package with their setup.as i said in the beginning, i won't cut up the car and it absolutely will NOT get a gearvendors.

While I am not disputing you, frankly I am surprised. I have been installing GV units for a long time. I have never had a customer service issue, ever. Aside from the fact that they work great and are very reliable, I always found them to be easy to deal with. They always call back promptly and are very friendly and knowledgeable. That sucks, though. All it takes is one sour experience to spoil the relationship...
Good Luck with your project,

While I am not disputing you, frankly I am surprised. I have been installing GV units for a long time. I have never had a customer service issue, ever. Aside from the They always call back promptly and are very friendly and knowledgeable. That sucks, though. All it takes is one sour experience to spoil the relationship...
Good Luck with your project,

i would've bought another GV had it not been for the bad attitude of their rep. it was worse than talking to Russ at Indy.

you can get a set of 2.76s for what, $100? and the beauty of the 8.75 is easy gear changes. try it for a while. i have 2.76s in my imperial until i ever get around to installing a 518 and they are great for freeway flying, and with a torquey 493" the car is still pretty quick. a lightweight e-body would only be better.
or just cut your floor...

I still think you should be talking to Art Carr at California Performance Transmissions about a TH 200-4R.
First gear 2.74, fourth gear 0.67. It'll need to be adapted but should require no modifications to the car that can't be undone. It does have the TV cable to worry about but that's probably a Lokar or Bouchillon kit. Or do the 4L65E like the Keisler with a standalone controller. It'll also need to be modified to bolt up, but that's the world you are in.
Good Luck,
R.

When searching for parts to build your trans, just remember it's a 200-4R, not a 200R4. A common mistake that might make parts searches a lil more tough.
Thanx for the clarification!!!
Off topic, Im guessing the 200-4R uses a lock up vert? Will it be a problem to have a 4k-5k flash vert with the 200?
I see the GM guys using similar flash speeds (lockup verts) in 700R4s.

200-4R came with Lock-Up torque converters.
There are different schools of thought about what to use with the beefed up versions of the tranny.
Art Carr (CPT) is an old school guy, and believes in non-lockup. I am not ragging on him, I have one of his 500HP 200-4R and non lockup 10" converters that I bought used to put in my A-100 van.
But I think that for highway cruising lockup might be better, and there are quite a few builders that like to use lockup, and sell beefy lockup converters.

If you can find a lockup converter that will live and also have a high flash stall, IMO that's the best of both worlds. The problem with the 518's is either you don't get lockup or if you do, the flash stall is pretty low, even the aftermarket ones mp sells are pretty lame.

I had a converter made with an extra low stall. It comes in handy when the diesel's torque is all in by 1900 rpm and the converter flashes closer to the 2400 rpm red line.

Someone told me the 518 is a direct swap for a 727 with no mods to the body needed.

Had someone come up to me and tell me about the 65 dodge pickup with the factory 440 hemi he bought new.

It is possible to put a 518 in a E body or a 71-72 B body with virtually no body modification... But the trans case needs trimming & a custom mount needs to be fabbed....
Putting a 518 in a 70 & back B body or an A body requires considerable cutting...

The important part is finding out how much modification is required on a 72 Imperial.

Not really, you've never impressed me as the kind of guy thats scared of a little modification... Off memory your Imperial may have a little more room to work with, fact is I seem to recall because it's full frame the torsion bar crossmember doesn't pass over the top of the transmission so there wouldn't be much of a problem...

True, but I'd like to avoid hacking the Imperial.
It's disturbing how little room there is around the engine and transmission in a car this size. Changing the plugs takes longer than it did in the hot rod with the turbos. The trans tunnel is pretty small too.
I've been looking at this thing from time to time trying to figure out how to stuff the turbos in there. There's lots of room for the turbos but getting the plumbing run without messing with all the other systems is a mess.

I'm sure it would raise a few eyebrows if they got some installation inquiries about putting that in an Imp. Their first question for you would be how/where you got it.
A car-sized version of that would be pretty cool, but we'd have to turn to Audi (I think) to get one.

A518 with either a JVX adapter or JW Ultrabell.
http://www.cuda-challenger.com/cc/index.php?topic=84774.0Many folks have done it in an e-body w/o hacking the car. Slapstick shifter works too.
I plan on doing the same mod.
I'm just curious on converter...for non-lockup.
They say, that you should get stall speed that's less than what you cruise at 65mph.
With 4.10 gears, and with a .75OD (3.07) and 26" tall tires, that means running 2600RPM. Does that mean I have to get a 2500 stall 'verter? That seems kinda low if you got a hot street engine.

Re: School me on overdrive transmissions for a RB - 06/29/12 01:49 AM
Someone mentioned earlier in this post that the 71-up Es don't need to have the crossmember modded but that the 70s do. Is that true? I never knew that there was a difference in the crossmember area between the years.
So, is there a difference that affects the install of a 518?
