2011 Suburban issues
Got a 2011 Suburban LS 1500 2wd, we’ve had since ‘11 and it has about 275K on the odometer now. Never had a problem, but a few months ago, we started getting torque converter shutter, so I changed the converter with a reman from a chain store. (Only place that had one in stock) Put a few hundred miles on it, and one night it quit pulling while wife was going down the road.
Getting a P0121 (TPS sensor 1) and a P0741 (Torque converter clutch system stuck off) Am able to reset the codes and it will move for a bit, then quit pulling again. Wasn’t able to mess with it the last few months due to work, so had a new TPS sensor and pedal waiting. Got both installed today, did relearn procedures and still same. Buddy is bringing my ramps and multimeter back tomorrow, so going to check wiring to TPS, and get under it to make sure I didn’t pinch a wire re installing the trans. I figure I need to get the TPS sorted first, then sort the trans TCC system. No dealers or mechanics with an hour and a half I trust. Had considered trading it in before the issues for a newer Suburban, but wife drove a newer one and prefers the 11, so I’m stuck with fixing it. Anyone had a similar issue? I hate chasing wiring issues. Thanks |
