Some info that may help

[Turbo Keith]

My car is a 70k mile car and a friend has a 20k car and we found we had the same problem . After driving and tranny gets warmed up it would shift really strange . When hot when you left a light it would shift really fast from 1-2 and 2-3 and so forth . My buddy did some research and phone calling to some trans guys and they said it would be the TCC Solenoid . Personally never heard of that part but I'm really not a trans guy . I see they are sold in the $25 to $40 range . Gonna install soon and will give some feed back then . I hope this may help , Keith

Classic bad TCC symptom if it starts acting up only after getting warm.
