Full line pressure with A4 SD tune
A few nights ago I flashed in a SD tuning file using EFILive/AutoVE Tuning guide in my 98 Z28 with an A4 transmission and have a problem.
The PCM is commanding full transmission line pressure at all times. All shifts are very harsh. I checked the transmission DTC fault enablers for P0101, P0102, and P0103 and they are set to “No”
The Engine DTC MIL Enablers for these codes are set to “No MIL” per the EFILive/AutoVE Tuning guide.
What can I do to prevent the PCM from commanding full transmission line pressure on all but heavy/full throttle shifts?
Thanks
John
