Looking to get some "real life" info here. I've read articals but the majority of them don't address the question as to: 1. What tranny did they use? 2. What modifications if any 3. What kind of maintenance was involved? 4. What tranny fluid was used?
Does anyone have any "real life", credible info on these four question? I'm not looking for opinions, just "fact" based info. Thanks for any replies

Early trans were iron case 18 spline,modified to slick shift/crash box. Later years were aluminium case slick shift/crash box. At some point they tried Borg Warner T-10 or "rock crushers" since NHRA was letting offbrands use the aluminium Chrysler boxes. The class progressed to any manual shifted transmissions,OEM or aftermarket. The maintance on the slick shifted trans was tremendous,mandating carrying quite a few spares for a weekend of racing.The weak part was the imput shaft and the stress when 4th gear was use since every other tooth was machine off.This was true to all the other gears and the sliders but worst on the imput. With the production of new "clutchless manual transmission" and the tech. today those trans mods back in the day dinosarous and should be left to the past unless your a Sox,McCandless,or Jenkins and have a big bankroll and love servicing a 4 speed constantly. I got rid off all my 4-speed stuff and even buried some aluminium cases out"behind the Hogpen",Bring your metal detecter and a shovel and I'll point you in the right direction.

Ha, Ha, No thanks. I'm content with what I have. I'm just looking for info. I did pick up an 18 spline, "full out" crash box last summer. It's totally different than the current "slick shifted" trannys. Different gears, sliders, etc. Real big "cogs" on the gears. None of the gears would interchange with a slick shifted unit. Thanks for the info.

I always thought that to be true until Ronnie told mne otherwise that they never used anything but 833's until lenco in late 72
Not questioning anyones word on anything but I recall Ronnie as well as few others that said they tried the BW and it wouldn't hold up.Anthony Christpher ran one in his Sox&Marten preped Cuda at PID for a short period also.You can get varied answers and opinions about what they did or didn't do 30+ years ago.I can only comment on what I saw.Ask how many AH cars are or were running a Chevy 12 bolt rearend today and see the

I purchased two A 833 transmissions from a known Pro Stock drag racer as they were switching to Lenco transmissions. The parts in the transmissions were all over the board. There were red stripe transmissions, but I never had one. These were 18 spline with the good input shaft but one was a 308 bearing while the other was a 307 bearing. I think they were both 2.66 first gear. One had Doug Nash sliders and welded dog teeth, the other had similar parts but was a Liberty, both worked very well in a 9500 RPM small block W2. Heard that they were not so good in a Hemi with a 2800 pound clutch. 1600 pound clutch and they would be fine. Today, I'd use GM synchromesh fluid, much better than anything we had then, although fluid never seemed to be the issue. No one used the aluminum case for long. The main shaft wanted to push away from the counter shaft and the aluminum was not good at preventing that. The aluminum tail shaft was a good idea, but are quite rare now.

The bigger splines sound similar to an old Doug Nash "Pro-shifted" Hemi 4-speed I used to run. The slick shifted sliders have every other tooth milled off. The Pro shifted have two out of three teeth milled out and the pro-shifted collars on the gears are the Doug Nash high strength nickel alloy parts with the wider teeth. It was a little more durable than the teeth on a stock collar. I heard from an old pro-stock racer who knew Ronnie Sox that Sox used to run a slick shifted 3.09 first gear ratio 23 spline trans. I guess eventually higher strength parts were developed...

I read that they used automatic trans fluid for less drag.

I went to the Liberty web site and it appears that the gears in my trans match the pro-shifted gears that Liberty has displayed. So I'm guessing my tranny is a Liberty pro-shifted transmission.
