Bob,
I know this topic has been discussed several times, but can we expect any improvements with shifting on the auto’s. On my 05, any program greater than mild TQ and the transmission just has a mind of it’s own. I know the throttle position senor has a lot to do with it and hence a software solution may fix it. Even with my Suncoast transmission I still experience the rapid shifts. If only each gear could be held longer? I swear my transmission shifts from 1st to 3rd, skipping 2nd and into 4th in a blink of an eye.
