You don't have the v.23 version do you? Also Dinan is going to have
nice tranny upgrade for us soon that is supposed to improve
on the overall performance. Get the v.23 first. imho.

I still have a transmission problem that they don't understand. When going up small hill at around 30 to 40 MPH the car sometimes lugs and should down shift. Does anyone else have this problem? They reprogrammed the trans last year (last spring) and claim that the software is up to date yet I thought that a new software update came out last fall?
