Question about 1994 GMC Suburban
Posted by Anonymous on
Check tranny fluid level and see it its brownish black and if it seems..this will be an indication of slippage..did you take the transmission to a reputable shop...did they pull the pan and show you that it had metal shavings in it? some shops just to save money only adjust the bands and this would probably be o.k. for normal level streets but lugging up a hill with marginal bands and flush system and install new fluid. if you went back and picked it up the next day i would be suspicious..be cause all shops when they are going to do a complete break down and replace all the bands clutch plates worn planetrary gears and torque convertors subcontract the overhauls they dont have the time to do these major repairs..so if they said come back in about three days then they might have done a rebuild. also if they didnt service the torque convertor properly by doing a flush on it they hold a lot of fluid, oil worn out fliud that would mix with the other new fluid and contaminate it again...if you only paid $500 to $600 to service the transmission i would suspect that they didnt do a complete rebuild.
there is one more thing that could cause this problem but it would also affect normal driving and that is a clogged up catylitic convertor. but i doubt it..drive on an open highway at about 50mph and step on it if it takes a long time and seems to struggle to speed up then its the cat.
can a get a rating, thanks!
