Alright I jsut pulled my c6 to clean it and it has on it s-92 on top and on the side it sasy D5UP-7006-AA I have tried to fina nay info online about it but cant, what year is it and speacs if anyone can help?
Well got it clean after 4 hours with a drill, with a wire brush and hand held brushes, I found out also it is a 1975 model supposedly out of a lincoln or van, but this c6 has fins running down the back of it others ive seen dont ,i found a couple more numbers on it, 6Z556321 on the case and D1AP-7A040-AA on the tailshaft.
i just saw a transmission like mine on overhaulin, it was in a 70 mustang fastback they built up at the sema show, and put behind a 514, only mine is stock internallybut it looked identical.
