TCM / TCU pinout for 97+ XJ's?
Hey guys,
Driving back home from college, about 45 minutes on the freeway, and things seemed weird. RPM seemed a little bit higher than usual in overdrive, seemed sluggish everywhere else. Check engine light too.
Got home and checked codes, and here is what I got:
113 IAT sensor high input (unrelated)
po700 transmission's messed up
po743 Torque converter lockup solenoid problem
So of course I want to unplug the connector from the TCM to the transmission/harness, and check the resistance between ground and pins to the transmission solenoids, for 12-15 ohms.
I've found info for all the connectors up to 96', which is a 2-rows at 16 pins per row, but the connector for 97+ appear to be a different style, 2 rows at 13 pins per row.
Does anybody have this pinout? Any other ideas?
Thanks!
