What happens when you run out of ATF transmission fluid?
Posted 29 July 2007 - 06:45 AM
Three weeks ago, I went to a major national chain service facility and had a transmission fluid flush done to my car that entails splicing the ATF fluid line to the radiator / oil cooler and exchanging all the trans fluid. Everything was fine until this Saturday aftenoon, while driving at 45-50 MPH, the trans suddenly starts to slip and the engine revs like it's in neutral. I coasted to the side of the road, but it turns out the spring clamp that held the rubber tubing to the oil line had come apart, and the trans fluid got blown out on the road.
So, the car gets towed to another branch of the service company where service technician #2 installs a better worm gear screw clamp around the hose, adds about 3.5 quarts of trans fluid (all it'll take in the sump) and then tries it again but still it slips BIG TIME. He ends up revving the *$^#%! out of it to move the car from the parking lot to inside the garage -- lots of noise and very little movement. If revving a trans without oil would be like revving an engine without oil, it's gotta be toast by now.
Now the service manager say they'll have their insurance adjuster check it out Monday a.m. The manager seems to have already accepted responsibility as he's already agreed to pay for the towing, a cab ride and a car rental. BTW, the oil lines are attached to the frame just below the battery, and it looks like the first tech may have bent the metal tubing towards the back of the car a bit, as the tubes are no longer parallel. I took pictures of the pipe where it came apart from the hose, and I have the original spring clamp which looks a bit mangled, so I think I've got the evidence I need to show it was their fault. (I can handle the inconvenience of an honest mistake, but if the insurance company jerks me around, I'll be slamming this company by name in whatever forums I can.)
Question: What happens inside the case when an auto trans runs out of fluid and gets revved? Major damage? Do you rebuild it, or replace the whole unit?
Thanks in advance,
