Can any one help? Have 06 GTP convertible, been reading the nightmares some are having with their transmissions, but none are mine. Quick shift(auto), (cold start) 1st to 2nd... 2nd to 1st, 1st will not engage until 15 mph? 1st, 2nd, 3rd... 3rd, 2nd, 1st- works find... most times*! All speeds are 25 mph and under. * Every now and then.. 1,2,3.. 3,2,1.. 1st will not engage till 10 mph, again speed is 25 mph or less. When running the car... 2nd- 1st will engage at 35 mph! Dealer is scratching their head.. they can not get it to do it. Their answer is the trany is not warmed up. Think they just don't have the knowledge.
