10-Speed showing its age

[Minnvmax]

2019 with 96k on a 6.2 She's starting to get rough. 1st to 2nd is often harsh and it seems to feel somewhat disengaged when letting off the gas. You know the feeling. I had the pan dropped early this year, so filter change and however much fluid to refill. The engine is still potent as hell. Can they be serviced mechanicaly? Has anyone see one fail yet?

Not sure about the ten speed but the 8 speed was junk right off the lot. Some of the symptoms you describe are what was going on with the 8. I'm not sure what can be done mechanically, except tear down and see what's inside. Someone should be able to help.

Was the correct oil used in it?

96k it should have been on its 3rd fluid change. Fluid is cheap, trans. not so cheap. I've taken multiple RWD and FWD trans. to 200k miles with no issues, many with tow duty.

Keeping fluid changed in these new transmission is more important than ever.  They are not the bullet proof turbo 350/400's of the past.  This fluid is what can go in all the new transmissions, AMSOIL's ATL. If anyone is interested in getting some, contact me and I can get you a quote.

I almost went Amsoil. I did put it in both diffs. I used the correct oem fluid for the Tran.  Sounds like I should do it again soon.

Very good idea.
