So the most desirable non electronic trans is a 1986-1994 A4LD, with 4.10 gears and moderate tires it does the job well.

Do you have a gearing ratio chart per transmission not derived from TRS? I've been wanting to make one for the tech pages which are being outlined, Mr. Howard has contributed some mod sheets we will include in the tech articles, I'm hoping we can come up with quite a resource. I have plans to scan my EVTM's though it will destroy them.

This gives me an idea

A4LD MUST be built by somebody who knows what the heck they are doing
Same is true with 4r and 5r55e
The A4LD can be rebuilt using 5r55e late model (sohc engine) guts......
1986-1994 is A4LD behind the Cologne 60 degree pushrods 2.9 and 4.0

Brett is now building these A4LD case and operations with 5r55e guts and upgrades

Now that is a A4LD I would run
Otherwise a crapshoot, the rebuild is often when the nightmare begins
Back when my BII was a 4.0 I finally had a transwerx built A4LD that was great, before that I had 4 of them (warranties)....they just do not hold up unless from the factory or rebuilt by someone who knows them and how to build them properly
I'm guessing here, but behind a medium built 5.0L-W,  (350-400 HP)..., the A4LD wouldn't hold up.

I was reading, on the Advanced Adapters (AA) Site, they mention a "4R75" Transmission, what's that, anyone's guess ?

I'm partial to the AOD idea, maybe an "E" even, but read the OD band is weak, not sure if this is taken care of with a good HP rebuild.

It should be easier than this.
