2024 2500 transmission leak

[Edward Liatys]

Yes I have the same exact problem I waited a month without my truck and they said that the seals are bad on the transmission that they are gonna have to replace them I have about eight thousand miles.

They just replaced them.

I drove it around a little today and it seems like it is leaking again it's the same little drip at the bottom of the inspection plug if anybody has any ideas please let me know.

Purchased new 24 2500 gas with the 10 speed allison.  Just a bit over 800 miles and discovered a drip at the bellhousing inspection port.  Found a TSB that pertained to the 2020 through 2022 with the exact issues I was experiencing. 

Took truck in for service a few days back and they uv checked to confirm the fluid in fact was transmission fluid which is now confirmed.

Transmission has been pulled however I am being told that the seals they don't have part numbers for so they can't order them.  They tell me the transmission in the gas truck is so new that they don't have the part numbers in the catalog in order to order them.

The service manager has requested that chevrolet approve the install of a totally new transmission in order to get me back on the road.

I hope this new transmission doesn't show up on the carfax report or else the truck will have a substantially deflated value.

Did you find a resolution to this issue? I am experiencing the same on my 2023 10spd with 8800miles, had the reseal tsb as well and the leak is back after 200 miles. I am thinking there is more to this issue then just replacing seals.

I took it back a few more times they cleaned the bell housing out it looked like it was residual they blew it out probably four times before it stopped everything seems to be okay now I have 11,000 Mi now on it keep me informed

Will do, I talked to the tech who did mine and they said they cleaned out the bell housing before and after the repair. They even cleaned it once the convertor was back in place to eliminate any residual. So they are thinking this is still fluid leaking from the front cover still.

This is not what I was wanting to see. I am about ready to go pick up a 2025 with the 6.6 gas motor, and the 10 speed. Can’t help but wonder if the issue has been resolved in the new model year trucks ?
