Transmission troubles
 

so i just had T-lok and 4.10 gears installed. got my trinity tuner and BAMA custom tunes. now when i am at wide open throttle my car hits 4th gear and immediately drops back to 3rd. when i let off the pedal it shifts back to 4th and stays there. i have had 6 different versions of the 93 race tune from BAMA and still ahvent been able to sove this problem. can anyone help? has this happened to anyone else?

Sounds like an obvious tune issue....

I know it's a tune issue, I'm just wondering if I'm the only one with this issue, or is BAMA having trouble with the 2010 automatics. I'm just hoping maybe someone else had the same problem and might be able to point me towards a new tuning company or a solution.

i uploaded the diablo 93 firm shift tune into my car. when i load the diablo tunes i have to adjust the axle ratio for my 4.10 gears. there is also an option for NOV adjust. i never paid any attention to it. so yesterday i looked up what it was and made adjustments accordingly. after the adjustments my daiblo tunes started giving me the shift issue. so i dialed the NOV back a little bit at a time until i no longer had the issue. I did the same thing with my BAMA 93 race tune that had been giving me problems. BOOM!! no problems at all. made about 6 1/4 mile passes on my favorite stretch of back road. nothing but smooth shifting!!!! I called Mike Wilson at BAMA this morning to make sure that the adjustments i made wont hurt anyting and he told me that it wouldnt. so i am happy to report PROBLEM SOLVED!!!!! I really really really appreciate the guys at BAMA and Diablosport for all the help and EXCELLENT customer support!!! I wont deal with any other tuning company. in fact when i need a dyno tune some time in the future i'm making the 6 hour drive from Pittsburgh to *gulp* dare i say it Philadelphia to have BAMA tune my car.
