Its been fine.
As far as I know it is the original 1991 A4LD, I've owned it and wheeled it for 7 years now. 5 years ago I installed a TransGo shift kit, and done regular once a year trans fluid changes. I added the extra cooler (kept it routed through the cooler in the rad and removed the factory external cooler) 3 years ago. I've never burnt the fluid in it or had water in it since I've owned it and never had excessive friction material in the pan. The bigger cooler was just extra insurance for me. This transmission has been turning 35 or larger tires for the last 5 years without complaint.
Guess I got the one good A4LD.
