My buddy who owns a performance shop who i work for on the side recently helped me come into possesion of a "1500hp" rated 6r140 trans. My current goal is to take the trans apart and inspect the internal modifications and copy the "recipe" if the claim turns out to be true. Currently I am looking for disassembly/assembly pdf manuals that I don't need to buy and specialty tool lists, anyone have any resources that could help me out? Thank you.

You'll def want a set of band removal pliers. Last time I did a trans that was the 1 tool that made the job. Hopefully someone else jumps in.
What for, exactly?


ATSG. They have paper and digital manuals for the 6r140. Complete rebuild instructions.
Highly recommend! The factory manual will give you the specifications as well as step by step disassembly/assembly overhaul directions.

It's been a while since I pulled apart a trans but the pliers make removing bands much easier. I just did a little searching and the 6r140 doesn't use bands. I stand corrected. You could have made that a little quicker and said "hey they don't use bands in those trannys". But thank you for pointing that out anyhow.

I was just curious - you never know what tricks people are using.

You can get a good look at a T-bone steak by sticking your head up a steers a$$, or you could take the butchers word for it.

I’d just call the company and ask. Don’t think it’s a huge secret. Bigger shafts, better alloys, upgraded plates and torque converter. Bet thats 90% of the recipes right there and far less work. But if you do it, please post pics that would be very educational to follow. Best of luck.

I would be more concerned with torque. That is how these transmissions are rated.
