when driveing down the road in od it is fine when i put it in d or any other gear i can be going down the road at 2500 rpms and let off the gas it will drop to idle and if i press the gas it will rev back up until it catches and goes again any answers would be helpful i have 410 gears in the rear an electrick water pump and all the emision stuff been tuned out the speedo was corected for the gears so its dead on with the gps i am running stock salad shooter wheels with 245/50r16 tires just thinking i need to have the trany over hauled help me out email me at mihailw@live.com

 

if it were a 4l60 i would say its the tv cable but u dont have one. i believe u have a tcc solenoid instead but then i dont know alot about tranies. have u taken it to a trany shop for diagnosis.

 

you can datalog and it will show what the tranny is doing as well including if the tc is locking/unlocking
