How do I determine which tranny I have?
Heres the VIN decode........1G2FW21F0KL204682

The RPO 'LB9' decodes to:

Have never tried to find it, and wouldn't know what I had if I did see. The Drivetrain data here mentions an A4 with 2.73 rear end.

Is that the do I have a TH400, 700R4, TH350........I'm lost.

This car is totally stock......has not had any replacement parts installed..

Thanks
Rick
