When im in OD for a while cruisin, the rpms will go up and it feels like it is slipping. If i slow down where is goes to 3rd or 2nd gear it quits and then gets to OD fine. Then it will do it again. Could it be OD is jacked up or torque converter jacked up? Transmission shifts great. Any Help would be greatly appreciated

 

You need to look at TCC lockup with a scanner and see what's being commanded.

It sounds like it's coming out of lockup.
