So I recently did a motor swap into a 4x4 truck. everything is running fine, shifting fine, fluid is full. CEL comes on for a PO710. Transmission Temperature Sensor Circuit "A"
Reached underneath the transmission and it slipped out of the pigtail. Plugged it back in, did fine for about 30 miles then came back on.
Figuring it was a dead sensor I bought a new one for 80$ and popped it in and I still have this freaking engine light. Do I have to hard reset the ECM and unplug the battery??! Anyone else having this kind of issue? This CEL is driving my OCD NUTS!
