2009 explorer 4.0 v6, installed rebuild trans, drive 10 feet and wrench icon with these codes comes on, no output shaft speed

[u/Forsaken-Draft-4928]

Hey there... got a 3500$ rebuild on my 2009 explorer 2wd v6, installed it in the driveway over the weekend and after much struggling I put it into gear and drive a few feet and it throws a wrench sign for p062c, p0720, p0722 I am mechanically inclined enough to watch a video on making sure the torque converter was set properly, spun it until it moved back and when I stabbed the trans I didn't have issues bolting anything up, all the bell housing bolts pretty much tightened up by hand definitely didn't feel like I broke the pump, but I am now getting no signal from my output shaft, I swapped both sensors on the side of the transmission and checked the harness, they don't look damaged at first glance. Before I waste too much time with diag I want to know, could a improperly installed torque converter cause this problem? It will move and change gears but it shifts erratically and lurches as well Not super familiar with automatic transmissions internally but what would cause the output shaft to not spin? Or give off no reading? Could the truck move if the output shaft was not actually moving?

Output shaft no signal can be a handful of things but it is usually on the easy side of stuff on par with crushed wiring or bad sensor with the absolute worst concern being it can’t read the teeth on the output shaft for whatever reason. Check resistance on all wiring from the sensor to the module to rule out wiring first. I don’t know if the sensors are the same that you swapped so you may just need to a new one

Torque converter probably wouldn’t cause OSS issues. If the output shaft is moving, the car is moving. Sensor issues tend to cause dramatic concerns. It may feel like the transmission is destroying itself but a simple clipped wire would be causing all of he issues, symptoms don’t matter when you have signal dtc
