Yes … the design was and they build their own based on the design … Last I knew … the GM is rated slightly higher …I think this is the 10R80 that was a joint venture between Chev & Ford.

Nice - it should cool a wee bit …The filter is OEM
I have seen it stabilize at a lower temperature. I don’t know that I can give you an accurate number.Did you see a difference in trans fluid temps?
The truck (2021 Chevy 3500 Duramax) has 35,000 miles on the clock and I decided to change the trans filter and install a PPE trans pan. I do spill and fills on my transmissions. The 10 speed transmissions don't have drain plugs in their oil pans. This is highly annoying for those who do spill and fills, so I decided to put the PPE pan on because it has a drain plug. The added bonus is the PPE pan holds a gallon more than the stock pan.
The stock pan with the engine off holds about 8 quarts of oil. Rather than try to lower the pan and dump the oil into my drain pan, I used my Mityvac to remove the oil before lowering the pan. I left a couple bolts loose in the other side so I could lower this side enough to get the small suction hose into the pan.
No, this isn't an Allison transmission, contrary to the GM marketing department. I'm sure Allison TES-295 would be good and TES-668 would be even better. However, the fluid I put in is a formula HPL blended based on an add pack that is designed for this transmission, by an add pack company that has a ton of data that shows this add pack works best for the 10 speeds. Would the Allison fluids work? I'm sure, but I'm going with a formula based on data and supplier reputation.Wilson, curious if you gave any thought to using Castrol Transynd..? that is generally Allisons high end fluid... donm't know if they actually recommend it for the baby Allisons in the GM pickups trucks
Wow - lots of similarities with common and nearly common parts. I've read that GM and Ford co-developed the light duty 10 speeds and the HD 10 speeds and this seems to leave little doubt.I took his pic and one of my 10R80 and slapped them side-by-side for the curious.
I agree with you about the fluid temps…The bottom line is that I only got not even a cup of additional trans fluid out of the trans when I heated the fluid from 145°F to 165°F. In the future I will just pull the level plug at 145°F and call it good enough. I see no reason to torque brake the fluid to 165°F, just to get an additional fraction of a cup of fluid out. My $0.02
Before I got my custom 10R80 dipstick I used the cold method (No, not the B&M one). All you do is check that the fluid is at the bottom end of the acceptable range with the trans cold. It only goes up from there.I agree with you about the fluid temps…
The 10r80 in my F150 specs the fluid level to be checked at something like 212° all while trying not to burn your arm reaching behind the catalytic converter.
I checked the fluid level around 185° or so and noted the level. Braked torqued it enough to get it up to the required 212° and the fluid level was nearly the same as before. There’s no way that small amount of fluid could possibly affect the operation of the transmission.
Those PPE pans are really nice.
Cherry Red Tintcoatnice write up....is your truck maroon?
i like that colorCherry Red Tintcoat
Used many - I do swap the nylon for a copper washer …For those who don't want to spend hundreds of dollars on a specialty aftermarket pan ...

These plugs work great. I've installed them on probably a dozen cars over the years and never seen one drip or leak and probably 200k miles of use.
And these are only $13, give or take a bit.
