Hi i have 59000 miles on my 06 H3 and i replaced transmission,cose i pulled 4500 pounds camper trailer,i live in Utah and travel all around big mountains didnt expect to trans. gonne that fast cose H3 is rated to pull up to 4500 p. to remaind i put only around 3000 miles with pulling camper trailer.New trans cost me with some other parts 2800 $ in GM service.

 

that's alot of money

 

Are you sure thats what did the tranny in? Was there fluid in it to begin with? Did the tranny do a lot of gear searching in the trip?
