Hi, looking for advice, 2004 Chevy 6.0 p59 ecu with 2bar Sd OS applied. Transgo shift kit installed so it?s waay too aggressive shifting when maf is failed.

On failing maf correct with mil on first error for the 3 maf codes, trans shifts brutally hard, have done some reading and the p59 does not have the check box for max line pressure on maf failure to uncheck.
Shifts go back to normal when maf is set to work.
Should I just drop the max line pressure in transmission table down lower to sort or is there a better way?

Regards
Carl
