I have a 1996 Chevy K3500 5.7l with the 4L80E trans
Recently my truck has been having problems shifting at the correct times and sometimes it shifts a little hard. Now when I get to around 50mph it jumps in and out of OD or lockup constantly. The truck has low power, which I am assuming is from the dirty injector. I am thinking it is possible it could have something to do with the TPS, but I have no codes for that. The only code I have is for my bank 2 being lean from a dirty injector. I will be replacing the injectors soon, But I would really like to solve this transmission problem.
Thanks in advance!
