Transmission whine - HELP!

Discussion in '1973-1991 K5 Blazer | Truck | Suburban' started by **DONOTDELETE**, Nov 19, 2001.

    Hey all, I just had the truck in the shop and had the transmission serviced (fluid/filter). It’s an ’88K5/350 TBI/TH700-R4. It's been a few weeks and now it started making a very slight whining noise, kind of like what a power steering pump makes when it's low on fluid, but nowhere near as loud. I checked the tranny fluid and it's definitely overfilled. Would this cause the whining noise I’m hearing, and could this have caused any damage? I’m going to dump the excess fluid in the morning, but I’m concerned that this overfilling may have messed something up. Thanks!

    I don't know about the whining but overfilling will blow seals and o-rings out if it's to full.

  4. Update: I called the shop and get this – I was told the mechanic filled the transmission to the full mark with the tranny COLD! Said he always does this because he’s seen “lot’s of problems” with people “going up hills and all the fluid drains to the back of the pan” causing the tranny to run dry…. Needless to say, I’m taking it back in tomorrow morning to discuss the situation. I just hope it didn’t get trashed!
