I ordered the aux trans pump this morning. Should have it within the next few weeks. I'll try and get some decent pictures and notes on the replacement.
This is what I have already replaced. Aux pump control module is what it is. I guess that’s the power supply, although I’ve never heard it named as that. It’s been so long I don’t remember which connector went to what.
If I've already replaced the control module (2010 version), do I need to buy the additional wiring harness or is the new 2010 version aux pump pigtail long enough to reach the control module?
As far as the removal and install, did you have to drain the oil or just remove the pump and bolt on the new one? Trying to gauge if I can do it at home or if I need to put it on a lift.
Bringing back an older thread. Has anyone swapped the aux trans fluid pump and wiring harness themself? Im ordering the replacement this week, just dont know the technical procedure for this. Truck has north of 225k miles on it now. I've already changed the trans pump control module a few years ago.
I'm considering replacing my aux trans fluid pump as well. Curious to see what your resolution is, and a parts list for everything needed.
I've already replaced the control module and wiring to eliminate the bump/jerk. Now I have problems with a stall coming out of hybrid. I believe my pump is...
I've never changed the aux trans pump on the transmission but I suspect that it has caused some of my transmission problems. The only parts I've replaced to date are the aux module and two connectors. I think I may replace the aux pump itself but have not looked for a write-up on it yet. My...
I believe there is an oil pressure sensor socket designed for this type of repair. I would suggest getting that correct socket vs a standard socket. You can do it with manifold on, get a few flexible socket joints and it takes less than 30 minutes. Replace the screen and the new sensor.
What’s the procedure for pulling the trans on a hybrid? I’ve installed some TH400 and 700R4 10+ years ago but those were on older trucks. I’m guessing disconnect battery, drain fluid and go.
Apparently it takes longer due to it being a hybrid. I do know it needs a new wiring harness because they changed the connectors on it after 2009. I could buy a reman unit online for $3000 ($1000 core) but I’ve only done motor work on this truck. Never had to disconnect the hybrid battery or...
Dropped the Yukon off at the dealer this week because the transmission has been having some issues. They pulled the pan and there's metal shavings galore. I'm guessing the hybrid trans fluid pump has given out and caused the wet clutches to grind away at themselves. Quoted $4000 for the...
I don’t think it’s related to that repair with the plastic parts. I think this is internal in the seat itself. Seat tracks normal and doesn’t slide unnecessarily.
