Is'nt the C3 the basis for the A4LD. I have read that a time or twelve, and that being the case it is a POS. Drains power, breaks at the drop of a hat, not as much fun, enough said here.
I'm actually going to try to run a stock C4 with a shift improver kit in my pinto(until it dies)
By then I will have finished my auto trans course and I would like to then build a rollerized C4.
