Just changed engine and various problems.
Hey yall. My old engine hydrolocked so how I had to replace it with a used engine. It runs fine but I'm having some other issues. The transmission is now shifting pretty hard and I don't think the torque converter is locking up. I also get a p0717 code. I didn't really mess with the transmission at all so I'm not sure why. The only thing I could think is I had one one connector with no sensor to connect to. It was on the right side of the wiring harness, located about halfway back on the side of the engine. It has the aluminum insulation so it lives somewhat close to the exhaust manifold.
Does anybody know if the 4l80 in this has a transmission control module that's on the frame or on the right side of the engine? I can't really find it. Any help is appreciated. I'll try to get you a picture

Glad you got it sorted out! Maybe there was another option on the donor motor? I am not familiar enough to know where it might go. Any other pending codes that might be a clue?

The only other pending codes are one for a knock sensor. I think it's just a bad knock sensor and I'm just going to put one of the old ones in there and see if it goes away. Who knows

I replaced both my knock sensors and having not done it before, took me 2-3 hours. Darned if one of the new Delphi sensors isn't bad, moving my issue from back to front. Apparently there was a bad run of Delphi knock sensors last year, and I found out about it after the fact. So I'll be diving under the intake manifold again soon, and probably replacing it with one that is NOT from Delphi.
