This pertains to transmissions.
Buick 2010 LaCrosse. Recalibrated for problem(didn't fix problem). It now shifts later in each gear. Don't like the way it shifts now. Can it be recalibrated back to original specs? Dealer says it cannot be done.

The tranny shifts at about 500 rpm higher than originaly. This was supposed to take care of a problem, but it did not, and now I an stuck with a tranny that shifts at a higher rpm, thus hurting my mileage.

Found A TSB for trans shifting at wrong time REf 09-07-30-016A Date Nov. 25, 2009 ask dealer if that was what they did. If not can they do TSB see if that helps

OK, I will do that, but I guess what I am trying to say is, can you reprogram a tranny without a TSB? In other words, put it back before the TSB that they put on?

That I doubt they may not have software to do that.
