Hi ! My '97 Montero Sports had this "Check Engine" light on. Grounding Pin 1 on the Data Link Connector, I got DTC's 11; pointing to a possible faulty throttle position sensor, 47; pointing to open or short lock-up solenoid, 49; pointing to a malfunction on torque converter clutch engagement and 54; for a 4th gear ratio signal. Then using a scanner tool, it showed P1750, again pointing to a failed solenoid either converter clutch solenoid, shift control solenoid or pressure control solenoid. I haven't noticed any gear shifting or idling problem. But, after resetting the error code P1750, idling problem came up. The engine would die down unless I turn the AC on. I intend to have the TPS replaced, but finding a lock-up solenoid is a challenge, not to mention the actual job to replace it in the transmission block. Any advise on how to go about the problem is highly appreciated.

you CANNOT use the engine code to properly diagnose the trans. You MUST access the trans computer for the correct code, as P1750 is a generic code that pops up for over a dozen issues.
