GojagSS Posted October 6, 2020 Report Share Posted October 6, 2020 Whats up everyone. My issue is when im coming off of a light or start driving down the road normally, when i get to 2nd or 3rd gear between 2000RPM and 2500RPM i feel a slight bogging or slugish feeling. I can have the truck in park and rev it and play with it between 2000 and 2500 and it does nothing. I have changed the spark plugs/ac delco double platinum 50gap and new wires. No codes, i have cleaned the mas air flow sensor before. Need some help please bugging the heck out of me lol. Quote Link to comment Share on other sites More sharing options...
pdwhite Posted February 23, 2021 Report Share Posted February 23, 2021 Maybe the torque convertor lock and unlocking not happening. My truck would do that around 2k rpm going like 45mph, Vmax with the 4L70E. It eventually threw a transmission slipping code. I put a transgo shift kit in and that helped a lot.
