BW-T35 -> AW4 Swap

Hello. After a few days of getting things squared away with the 71 Javelin, I'm starting to have serious issues with the BW automatic and the only references I can find about this transmission are related to the BW T35 series via Cobra Transmission. With a total nearing 72 parts this looks like an antique torqueflite and I've already been down that path with rebuilding an Eagle TF998.

The current symptoms it has is that shifting from Park, Reverse and Neutral work fine but it takes its sweet time engaging into Drive and now it requires feathering the throttle at high RPMS just to get it moving in a forward gear. I don't feel any shifting into higher gears either.

I'm thinking this may either be a burned up clutchpak or loose band. I don't have any guides on how to adjust it either. One of the things I've been looking at recently is the fact that none of us got a properly evolved automatic for these cars until 4 years AFTER American was bought and buried by Chrysler. There's a line of Toyota transmissions via Aisin Warner that came equipped in Jeeps that I find in the yard from 91-01 and I'm wondering if an AW4 from a wrecked 97 Cherokee is a sweet ticket to getting this working proper. I'm aware this was issued behind the 4.0L but that doesn't seem to stop a few people from bolting this up to an AMC V8.

One of the stipulations that worried me about doing this is the fact that this BW marriage indicates I have an antiquated engine with the flat crank flange and because the engine is external balance, I may need to fabricate a counterweight onto a flexplate to keep the assembly balanced. There's a lot of dependencies in this already. What should I be focusing on first?

Yeah I've gone through some of the notes. Here's the thing. My attention is being constantly divided by two cars that either don't run or don't want to move. They're unstable. I have a donor up North for a late crankshaft and some modern ignition parts and accessories that I intend to use in a future engine build. I was supposed to go check that out today. Not with all of this mess.

The Borg Warner automatic is not the best thing to have as parts for it are a pain to find and should I dare go through the process of rebuilding one, it's not going to be on my already full work bench. It's going to be another 3 month and $2200 circus by some dumb mechanic that likes to play keepaway with these ^&% things and by the time I get it back it's going to be in the same poor shape it was in right before it started slipping. If I dive into a AW4 swap, it's going to be a straight pick and swap or I'll have to cut my losses. I'm not sure if I have any business already chasing newer parts for this car but I really don't know anything about this BW auto.

Sounds like the forward clutch is bad. ( Forward clutch means the clutch that is applied in ALL forward gears. )

Forward clutch and front band is 2ND. gear.
