I had my tranny fluid and filter changed at about 40 thousand miles and now I have 83 thousand, I am having some problems with it hanging in overdrive and not wanting to downshift when I give it gas, it groans when on the highway trying to come out of overdrive on hills but has done this for quite some time. I take it to the dealer and he says it looks like a good time to put in a new tranny for 2500 bucks, but the mechanic says it wasnt uncommon for them to make mistakes and put dextron 3 instead of mercon 5, so he looks a little closer and smells the fluid and says it looks good but smells a little burnt but not bad, then the biggie... he says that it is overfilled by at least a quart and that it shouldnt be like that, could this cause problems? he looked at the service guy and shut up. I have heard that these trannies are sensitive to the right level.
