TRNW-2: FW6A-EL Mazda 6 speed units Pressure Switches

[Dan Hogan]

Fishing for some experience with these 6 speed units.

I have a 2018 CX5 in the shop with a customer concern related to a bumpy 2-3 and 4-5 shift at times.  No codes are present.  We are going to do a pan inspection.

Ive dug into the Fix database and see a similar issue posted by Dean down in NZ related to a TCM failure.  I suspect I may have a pressure switch issue as the shift concern on the 2-3 shows a double tap on the 35R pressure switch PID.  When the shift is smooth and normal, pressure switch closure is one event.

Has anyone encountered the TSB described failure of the pressure switches on these units?  Always codes?  Shift quality directly affected?

Thanks for any experience with these units.
