I am looking at buying a TKO600 or T56 for my 1968 Charger. Anybody here had any experience installing one in a 68-70 B Body or seen one that was installed with no cutting involved OR is there alot of cutting involved.

You definitely have to cut. FWIW, I helped with a 69 RR and a 70 Cuda. Both floor humps partially cut out and if I remember right the B was worse than the E. Both cars were fit and cut on a lift going up and down numerous times and lifting the trans. in and out. It was at a working collision center so I just did the cutting and fitting and was not involved in welding and replacing.

T56 is way fatter than any mopar trans from back in the day. To get that in you will have to cut floor and torsion bar crossmember.

I think the TKO kits that used to be a big thing can go in a factory torsion bar crossmember but in order to clear it the transmission has to sit way too low at the back for a good pinion angle. Floor mods still required and I believe torsion bar crossmember cutting if you really want the transmission to sit right.

If cutting is a problem for you, there's always the OD transmission from Passon that bolt right in.

These guys are making a bolt in crossmember for the area that has to be cut. Todd Ron Restorations https://www.facebook.com/ToddRonRestorations/ , or look up "Todd Ronald Johnson"

If not cutting your tunnel is a option then wait for a passion 5-speed but if cutting your tunnel is an option and you want an awesome new experience in banging gears like never before than I highly suggest you do it. Got to finally drive my close ratio T-56 Magnum XL from SST last week and unbelievable. Glad I didn’t wait on the passion.

I really dont want to pay $6K for a transmission from Passon so I will need to research how much cutting is needed.

Do you have any pics or video of what you had to cut in order to make that T56 fit in your Charger?

That sounds interesting but facebook isnt my thing really. I wish there was some other way of contacting them.

there was an article, hotrod maybe, where they put a t56 in a 68 or 69 charger. google it. they had some good pics of what cutting the corssmember looked like.
i keep coming back to it for my 67 coronet, i could cut and weld up the crossmember but i will probably just keep a 727 in it...less work and money and i don't mind autos i guess.

I have two of them, an A-body and a B-body version, best money you'll ever spend. Beautifully built brutes, zero cutting, 100% bolt in.

Don't be fooled, there will be cutting required for either transmission to provide clearance and proper driveline angle, don't rely on the kit mfg for the optimum install for your particular application...if your not inclined to modify your vehicle, then don't bother with a TKO/T56, go join the decade long Intergalactic waiting list for a bolt in transmission...

IMHO If your going to go for maximum performance and OD advantage, go with the T56 Magnum .50 OD, otherwise a TKO600 in the .64 OD can fill out most OD requirements...tailor your OD ratio choice to either your existing engine/gear/tire combo, or build a driveline around the OD ratio of your choice, as well as intended usage for said vehicle...

Depending on how much you want to spend, expect to start off in the $4K range and up depending on your requirements and choice of transmission, IMHO if you choose either a TKO or T56, Silver Sport Transmission is your best source for a one stop shop, and their kits are a more refined product, where as other kit mfg offerings are based/copied on earlier kit offerings from assorted mfg's and have seen no updates like SST's offerings

Yeah my budget for a new transmisison would be somewhere in the 4k to 5k range all in.

If I dont have to cut the transmission tunnel or modify the shifter opening hump then I would be fine with a TKO600 or T56magnum but it sounds like the T56 would require cutting of the tunnel since it is alot wider.

The TKO600 shifter location for the 68-70 B body comes up in the tunnel center line, an offset bracket brings the shifter into the factory opening on a 4spd CONSOLE equipped vehicle, the BENCH mount shifter will not fall within the factory opening, although the kits on the market supply you a piece of sheetmetal to simulate the factory 4spd hump, I'd suggest you install a factory/repro 4 spd hump (unless your vehicle is already equipped?) as you'll need the clearance for the tranny as well as underfloor cooling, as an OD generates some good heat in prolonged OD operation

The TKO kits all drop the tail end somewhat to make concessions, this results in driveline angle changes, I like to avoid that, and will trim out what's necessary in the torsion/tranny crossmember to achieve a proper drive line angle, as well as modify the kits tranny crossmember to achieve proper drive line angle

You could get a 4spd overdrive gear set for your 833 from Passon or Brewers if having overdrive within a budget is your goal.

I've thought of that a time or two. Brewer's offers one?

I can get you either T56 Magnum or TKO transmission for way less than the big name Elite Tremec dealers. I am a new Tremec dealer and a Veteran owned small business and have a reference from Tremec themselves. I personally have a T56 Magnum close ratio in my Cuda and would never use anything else.

Both units will require cutting. There is modified TKO600RR designed to fit better due to the revised shifting position but it shifts worse and cost more that the T56.

I can also get Quicktime bells for Big & Small Mopar/Gen3 Hemi as well as Mcleod flywheels and clutch kits.

I’m sorry, tried to post a pic but having problems. In the T-56 Magnums they have, they offer 2 ratios. A close and a wide, .50 and .63. I like the close ratio a lot better because it’s geared better. The wide ratio is geared to low in the first 4 gears then drops off big in the 5 and 6 gears. SST gave me an option to go glose ratio the first 4 gears and then install the wide ratio gears for 5th and 6 thus giving a little bit more RPM in drop while cruising but I really didnt like my motor lugging down in that RPM range so I passed.

Yes! I feel that the close ratio is the way to go. The RPM is very usable between the gears from 2nd-5th. I have a 3.91 rear. First goes pretty quick and 6th I mainly use for saving gas on long trips. I have had the T56 Magnum in my car for over 4 years and never any issues.

Tremec stated that the wide ratio will be phased out eventually though as the demand is simply not there. They sell way more close ratio versions. I became a dealer and got a second Magnum to have as a spare haha!
