What is the name of the fluid in a T-case for the 07 H3 ??
I had thought it was straight ATF, but someone told me it was something more special
Thanks

 

I was told to use Dexron III/H or manual transmission fluid part number 88861800 in the TC when I went to purchase from a GM service counter. I went with the manual transmission fluid since the did not have any Dex III. Hopefully I wasn't misinformed.

 

"Owners Manual", read it, love it, live it. Use what it says for your truck if you plan on keeping it under warranty.

 

Thanks all . . .

Vehicle is at another location and it has service manual,
other wise you're right I could have looked it up
I do use that manual allot

 

manual transmission fluid part number 88861800 is what is in the manual.

 

Wasn't tryin to be a smart azz. The 06 Manual says Dex III; 07 says MT Fluid; 08 says Dex IV; and, right now I can't remamber what the 09 or 10 Manuals say on the subject. So, do what you truck's manual says (even though IMHO any will do) because that way if you have a failure, and still are in warranty, no way can they claim you put the wrong stuff in and we refuse to cover it.

 

sounds like our egypt foreign policy,in,out,go,stay,go soon but no rush.
whats a mother to do

You a smart ***,?? never !!
Your posts have more info and useable logic than most

I just never really knew exactly what "manual transmission fluid" was . . .
I believe that's what the manual for a 07 H3 states

 

FYI the 2010 Manual says Dextron VI.

 

Headed to the dealer on Friday for the T-case fluid change
Hopefully they will know the exact fluid for an 07
Just incase, I may want to bring a print out of these posts
you know, as back up
