How does the Force Motor Work?
Does the plug to the force motor only work one way? I saw it was off, plugged it in, and now my transmission shifts slow, and there is no TCC lock up in overdrive.
The transmission was remanufactured by a local shop. Things worked great when I got it and installed it. But, it had a leak I wasn't aware of, and the same day I took it into the shop to be checked out, it ended up slipping in 3rd and 4th just hours later. I was told to put two quarts in it and try it out. I did and things worked fine. Went back to the shop with it and they determined the gasket would need to be changed. But, they weren't willing to do it under warrantee because I was the one who installed the trans.
I changed the gasket, but unbeknownst to me, I got the plug that goes to the force motor stuck inbetween the case and pan, crushing the plug. Not sure how it pulled off the force motor, but there it was. And, I only noticed it, because the pan was still leaking. So, I pulled it again to see the crushed plug. I used a screwdriver and opened the connectors back up and slid it over the terminals on the force motor, but I don't know which way they go. Now, the transmission shifts slowly between every gear, unless I have the throttle nearly floored. And, it seems the TCC is no longer locking up in OD.
Would this be a symptom of the force motor not working? Can the plugs be flipped and still connect to the terminals? Would the TCC not lock up if the force motor wasn't operating properly? Is there anyone with a PDF of the 4l60e GM service manual?
