So, the wrench icon showed up again (!) - after the dealer cleared it 2 days ago. I took it, while the icon was on, to the mechanic I’ve trusted for nearly 20 years. He runs a scan on it and comes up with a “stored code” indicating a bad transmission fluid pump and says “You have to replace the entire tranny”
😳😳 REALLY?!?!? 😳😳

 

Uh no... you just have to replace the pump assembly. Does require pulling the transmission.
Assuming you have a 10 speed tranny, the pump is replaceable.
It is a unique design used in the 10R80, and the GM 10L80 transmissions. They actually designed the transmission together.

Remove the valve body and then you can remove the pump.
4 bolts holding it in.

 

Just to confirm - Does, or does not require trans removal ? Since the valve body does not (that I am aware of)...

 

Most likely he is scared of that trans. I think most indis are. Easier and safer to put in a rebuilt.

 

You said “10-speed.” I’m pretty sure this is a 6-speed. Is it still possible to replace just the pump? Most places I’ve talked to say they won’t know until they drop it and open the case. FYI: parts and labor for a reman
unit = $5,200. (!)

 

How about telling us the trim level and engine of your truck so you can get accurate info.

 

2016 F-150 XLT with a 3.5 Ecoboost and 101K miles, 2WD.

 

Oh, then yes it is a 6 speed 6R80.

 

You can do it with the tranny in place, however it is easier to pull it and do a full inspection to make sure the the drive gear coming off the torque converter is not damaged.

This is all moot of course since this is a 6 speed and not a 10 speed.

 

The Trans needs to come out for the 6 speed pump
