Question
If they were auto they got the 4L60E
Zo6 was/is manual only: T-56
Cokeroker: if it's stock you have a 4L60E. If someone transplanted a 4L80e into your car you'd probably know because it takes some work to get one into an F-Body.
Also, on F-Bodies only the 6-speeds were available from the factory with 3.42's. The A4's got 2.73's or 3.23's
