What should I service this 10L80 at?

[BrendanC]

Just trading emails with a service rep (huge dealership) asking cost of ATF and filter change (Tahoe 10 speed). He said we don’t do that - the way we conduct the flush cleans the filter.

this is so wrong and outright lazy. it isn’t hard to pull the exhaust down to do it right.

No experience here but it sounds like an inline filter would be a good idea on these

Not really. The factory filters are an extremely nice filter. They're far different from the old 'rock catcher' filters on old automatic transmissions. There's just nothing out there that will catch and trap the contaminants that are causing the valvebody wear.

I have a post somewhere on here of a 10R80 filter C&P, can't find it at the moment of course.

inline filter is a great idea. often cooler lines catch a slip stream or full flow off the torque converter/rest of the transmission before it gets discharged into the pan so catching it before it makes it to the pan filter is beneficial. i have inline filters in all of my vehicles (XG8a sized filters)

Love me some inline transmission filters. I’ve used both magnefine or remote-plumbed a spin-on. Both did good. Given the space I’ll do a spin-on, which can also support a temp sensor for a real gauge.

The aluminum these units shed is off the charts & It's so fine I don't think any filter media will trap it without causing a restriction.

Here's 10L80 separator plate, You can see all the aluminum debris, One of the screens got so loaded up it blew out.

@clinebarger - that’s incredible. That’s a lot of debris.

@clinebarger to the rescue, as usual.

I replaced the OEM plastic transmission pan that STUPIDLY, and to pinch pennies I assume by Ford and GM does NOT have a drain plug!!
I went with The non deep PPE pan on my 2022 Mach. No complaints after a month or so of driving.
I like that it is aluminum and that it has cooling fins and a magnetic drain plug.
Like many of people have sit on here about the transmission, eating itself. Due to aluminum working against a much harder steel, and therefore the aluminum filling the transmission with aluminum shavings, doing a draining fill of transmission fluidwith every engine oil change would probably be a good idea.
Ford replaced my 10R80 transmission after just under 10,000 miles on the car. Of course, after fighting with them and going to multiple dealerships and different states.

On the 24 Tahoe with the 10L80 tranmissionmission. I’m trying to plan ahead and form a service interval plan.

I am only at 10k miles. I know I’m very early on, but I love this truck and want to keep it for a long time.

I guess I’m trying to decide:

1. What should the first service be at?
2. Should the filter be changed at this first interval? Fluid only?
3. Should subsequent services be the same mileage intervals?
4. Filter every time, or only every so often?

If no to a filter every time, perhaps I should change to a pan with a drain or maybe I’ll have my welder FIL weld a drain bung to the pan.

Wonder if an aftermarket pan or a drain added to the OE pan would make GM void a warranty in the event of blowing up a tranmission.

I come from the world of servicing a 4L60E every 20k with drain and fills and every so often a filter… with long healthy tranmission life. For example I don’t like letting fluid get nasty. I feel you keep the fluid clean they’ll stay healthy.

I did 50k pan drops on my 2020 3500 and sold the truck at 194k miles with no tranmission issues.
