The trans. seems (on occasion) to not want to go, then it catches and takes off. Only does this on occasions, and only when taking off. Otherwise it works fine.. Is this an internal trans problem, or what? (Not an engine problem)

 

It sounds to me like a dirty throttle body

Perhaps hesitation is the wrong word...The engine speeds up but it momentarily acts like it is in neutral. It seems to be more prevalent before the engine warms up. ATF fluid and filter has been changed.

 

hey,
I have had a similar problem. Sounds like a bad solenoid in the transmission. Had a problem in my 06 montana sv6 where it would it would act like its in neutral and suddenly bang into gear from a stop. I got a code for the pressure control solenoid but changed all 4 of the solenoids as it is not an easy job to get to where the solenoids are at.
