727 specialist

check my add in parts for sale a have a killer deal on a turbo action 727

How about tranzact trans, anyone running there stuff? isn't that part of indy?

I’m very impressed with Rick Allison at A&A. His company and machine shop is top notch. He has newer CNC equipment and from what I’ve seen, his products are of high quality. Plus, he’s always gone out of his way to help me out. Granted, I’m not a big racer but I know what good customer service is.

I highly recomend the 727 SPECIALIST for MOPAR 727 and 904 transmissions. I have been running them since 1997!! I am also running a Griener reverse manual valve body bought through Keith. We have run a best of 9.49@139.60 in our 1970 GTX.

I would like to update this thread due to needing a reliable source for a street/strip 64 big block 727. Anyone in the past year or so had any experience with Keith aka 727 specialist?

I have his transmission in my junk, plus just had him go through a stocker for my Volare. Very good trans guy. He's also doing his own valve bodies now.

He took over the Griner design I believe

Yes, and he's starting to add his own touches now too.

we had very good luck with the 727 Keith built for us with a 2nd gear start 1200Hp nitrous car 7.73/170.

I used CRT (Cope) for years with good luck. Then I had him redo the 48 RE in my tow vehicle, and what a nightmare. Was shoddy workmanship and sent me the wrong converter twice. At first he agreed to cover the second R & R, but then pi$$ed backwards and told me he would only reimburse me for a converter. I’d look for someone else if I were you. Jim.

If you want the best 727 or 904 street and strip or all out race trans contact Dave Smith at Pro Trans at 661-940-7400, he is the Mopar tranny Guru
Their in Texas now, not in SO CA, they got smart also and moved out of CA

I really think that something has happened with Cope. I know of other problems folks have had.

I have had John do 3 transmissions for me , always a bit salty .. the last big block one I bought had couple small issues, when I asked for advice he was kind of grumpy ,

I'm going to have A-1 do my next transmission. They are fairly close to me and they have built a bunch of transmissions for guys I know. https://www.a-1perf.com/

You're being kind Bigdad.

I did call Cope at one point to talk to them about building a transmission for my Duster but the guy I talked to didn't seem interested in talking so I moved on. Not sure if I was talking to the owner or not, I think I was. I didn't worry about it much, he is a distance away and shipping back and forth was going to be expensive.

I've talked to Robert at A&A a couple of times and he seems to know his stuff. He helped me pick the correct parts for the build. So far I really like the A&A parts. Just wished their website was a little more up to date. If you call them you'll discover that they have new products or different products than are on the website. I guess they are a phone based business rather than a web based business.

I’ve reached out to Keith (727 Specialist) a couple times on a couple older Griner transbrakes I had. Was always easy to get a hold of and had all the answers.

As Cab mentioned if/when I need a mo-better 904 I’ll be calling Pro Trans. Dave and Darren have helped me a ton over the years with my transmissions. Good people.... great product.

You’re in good hands there Andy... they do know their stuff.

AJ Casini at BGR quality and great service at reasonable price

A recent 727 build video.

I am running one of the new 727 Specialist valve bodies that uses the Griner design.
Very consistent and quick on the release!

Interesting that he recommended a shimmed later style front servo over the early small pin style.

Well I asked and you guys recommended! After using my local guy to rebuild the trans in my pristine 64 Sport Fury convertible 426-S it lasted all of two weeks. Actually it never was right. I did what I should have done in the first place and had Keith Long (727specialist) build me one utilizing one of his nice cores with 67 & up internals and a new 2800-3000 stall converter. It arrived in a very reasonable time frame with output flange included. I installed it this past Friday evening, filled it with ATF4, hit the key and breathed a sig of relief after good firm engagement in R & D. Test drive was the best I had witnessed after owning this car for 15 months. I was finally happy. Back on the lift and up there were zero drips, dry as powder. Again, elated! 7 hours later I was able to attend our last big show here in my area where the Sport Fury garnered best in class out of 22 cars. Thank you Keith for putting an end to my nightmare and providing me with a trans I know will last me for a VERY long time! And thank you to the Mopart's community that led me to the right decision!

Do you know what clutches are in your trans? I've been told to run Dexron 6 now that my dodge transmissions have performance clutches in them.

Here is a break down of what Keith sent me.....remember this is a street tire set up.


Ft pump gets rebuilt with new bushing a good housing -checked gears - a new seal and o ring. rear part of ft pump gets machined if necessary.
Four borg warner clutches are used. clearance is .070.
rear clutch retainer Clutches are raybestos carbon type. Four clutches are used. clearance is .020 to 045.
ft band is a custom design using carbon lining and the flex band. .
Rear band is custom design using an oem type lining.
I use a three or four pinion front planetary making sure the splines to the input shaft is a good tight fit. using a good thrust washer. Rear planetary are usually three pinion with a good polished thrust washer.
