Message Guys I need to post this one to the board for assistance.

Stats:
No error codes from ECU or TCU.
OD button Functions.
Fluid and fluid level good.

Problem:
Transmission shifts fine when cold (including on/off OD button function), but once the car and transmission get up to operating temp the transmission shifts down to 3rd and stays there regardless.

I have a large aftermarket trans cooler.

Any ideas?
