So I recently replaced the governor pressure sensor, TCC/OD solenoid and governor pressure solenoid as well as the 3-4 accumulator spring. I got everything back together and now I have two codes and a **** ton of slip, it takes a lot of power to get going and I have the aforementioned p0753 code and p1763 code which is governor pressure sensor high voltage. I’m pretty much at my witts end with this transmission and I’m completely at a loss

 

I think the slip is because of it still getting fluid through the system and clearing air out, not sure in the high voltage, I have consistently had that issue and I’m starting to think it’s the wiring harness

 

If you idle in gear, for a minute or two, that should purge all the air out of the system.

Sounds like you got a pinched wire somewhere.

 

is the pinched wire for high voltage? And I also adjusted bands, could that be the slippage issue if I did it wrong?

 

High voltage is pretty relative. The pressure sensor is on the 5 volt bus. (maybe the 8 volt....) if it sees more than that, the computer gets real confused. Have a look at the connector on the outside of the trans. I have seen the wires pull out of them, and short together, right AT the connector. If that looks good, you may have to dive back inside.

How did you adjust the bands?

 

I’ll check the plug tomorrow. The bands I did a bit sketch. I have a torque wrench but I don’t have the right bits to use it on the reverse band and my only bit for the first band was a screwdriver bit that didn’t work in the torque wrench. Anyways, I tightened both a little past snug and backed the reverse band off by 3 turns and the first band by 2.5

 

That should be close enough..... I see a lot of opinions on how many turns to back 'em off..... I just paid someone else to deal with it. (that, and I REALLY didn't want to be crawling around under my truck..... my concrete floor is pretty cold.)

 

lol, I have a neighbor who’s a mechanic that is always offering to help me. So I’ll probably either ask him to try or I’ll do trial and error on the first band. It just slips so much, it’s like I’m driving a manual with a worn out clutch

What happens when you clear the codes?

 

both just come back almost immediately, regardless of the truck being in motion. I apparently ran out of gas so we spent a load of time starting it and I cleared the codes before starting it and both came up immediately
