i have a 1989 Suburban with a 6.2 and when i am driving over 35-45 and take my foot off the pedal the truck sounds like it has "J" brakes like a big rig. it also dogs really bad sometimes when going up hill with no power and loss of speed. the trans is new not rebuilt with about 40k installed at the dealer.is there parts they reuse off the old trans the could cause these problems,i'd hate to replace trans again at 1800+
any help with this would be appreciated :cool:

Thanks Paul
