I have a 99 sable, standard 3L engine. 80,000 highway miles. When transmission hot I have a 1 to 2 shift problem. At low partial throttle (as leaving a light in heavy traffic) it sometimes shifts way too soon and violently (chirps tires) then downshifts back to first with just a little more throttle. At moderate throttle everything works fine as when cold. Seems worst after driving on freeway. Fluid level is OK. Not predictable enough to take to dealer yet. Any ideas?????? Dealer wants $200 to power flush.
