Disable po757 DTC What are the steps to disable the PO757 code with LSedit.
I can reset the code with EFI live and car shifts into 3-4 ok but as soon as it downshifts to 1-2 then car won't shift into 3-4 again. When I parked the car for storage 3-4 worked great. Brought car out of storage and drove for a 1/2 mile and won't shift into 3-4.
I'm sure it's due to KR or my convertor (Vig 3200). I have a new Yank PY3400 and Performabuilt level III ready to install - but want to wait until I get the new 408 long block due in May.
In the mean-time would like drive the car. Car is parked now - can't get it to shift into 3-4. Current transmission has only 7k on the rebuild - all highway miles - no racing.
I have LSEdit and EFILive.
