Does anyone know the shift points (rpms) of the f4a51 Mitsubishi transmission? I have experienced a torque converter lock up shudder, with a 2-3 shift flare- has anyone had the same or similar issue.

Trans is no smarter than box of old dry rocks... TCM tells trans what to do..

Been a few updates for PCM and TCM you likely not had done back when to bring it up to current versions software..

I want to say GDS will likely offer 48 as latest for PCM (SM 2.7 INTERMITTENT HESITATION),,, and 40 as latest for TCM (SM 2.7D A/T SHIFT FEEL IMPROVEMENT)

Get with dealer service fella and have GDS plug in and verify all up to date,, just go to ECU UPGRADE, select ENGINE, let it read ROM, and see if it offer anything.. do same for TRANS, read ROM, see if it offer anything

After doing trans update,, reset Trans adaptive learn

GDS may prompt to plug in via 10-pin connector maybe also,, been a while,, it'll show in menu what needed to access, either DLC, or 10-pin to get at module for update
