MT82- 6R80 swap S550 code P163E

I have a code P163E for transmission control module programming error invalid checksum after performing my auto swap in my 2016 Mustang GT. PCM is a new unit from Ford. Everything in swap done as clean as OEM. Have changed all as built data to match VIN number from auto that i chose. PCM had PMI done with IDS. All data shows up properly, everything functions correctly from every module, not one code in any module except PCM with this P163E. I have everyone scratching their heads around here. Anyone have any insight? Recommendations? Thanks

Have you checked to see if the transmission auto switch was modified, trans load switch and trans_type? just suggestion

P163E TCM TCM programming
error
The TCM has detected an
invalid checksum.
• MIL ON
• Default to 1st or 3rd
gear
• Maximum line pressure
REPROGRAM the original
PCM with the latest
calibration. CLEAR the DTC.
TEST the system for normal
operation. If the DTC returns,
INSTALL a new PCM. After
installing the new PCM,
PROGRAM it with the latest
calibration and PERFORM
the Solenoid Body Strategy
Data Download. REFER to
Solenoid Body Strategy in
this section. ROAD TEST the
vehicle and PERFORM the
Adaptive Drive Cycle,
REFER to Shift Point Road
Test in this section

I have done what you posted bob450 with no success

Did u ever figure this out?

Anyone else run into this? What was your solution?

The one person I know that ran in to this issue was using transmission solenoid data from a 2011-14 transmission. The computer would not accept it. I would validate what year transmission the car came from and reprogram the solenoid id and strategy.

Thank you. I spoke to the person who ran into this before... likely same guy.

We tested with a strategy from a 15-17 and same code; actually same strategy that resolved his code.

Already replaced PCM and now waiting on a new valve body to test with. Unsure if hardware or programming related, but PCM and valve body are really the only hardware pieces involved so we'll see.

The new valve body resolved code P163E.

There was no visible damage to the valve body and no other codes were being thrown.
