1st thing I would do if you believe the wrong fluid is in there and that it is causing problems is to
STOP DRIVING THE DARN VEHICLE!!!!! Why would you keep driving it if you feel the wrong fluid was used and that it is damaging the trans?
I don't get it? That is like going in for an oil change and discovering the mechanic only added 2 qts of oil but you keep driving it anyway despite the engine noise. STOP! No more 130 mile trips. No more 1 mile trips until you figure it out and correct it.
Every mile you drive the vehicle if the wrong fluid is causing your issue makes it worse. Also, it hurts your position if you need to fight it. The more damage you cause by continued operation the harder it will be for you to prove the fluid was the cause initially.
Go back to the lube shop( in a different vehicle until you are sure they will bring it in and do the service - then come back in the problem vehicle )and ask that they put the correct fluid in. Stand firm but polite on the fact your receipt shows the wrong fluid was used and that noise developed for the 1st time after the change. Request a fluid swap to the correct fluid and have it noted on the receipt that they did the swap because the wrong fluid was used initially. Very important that you get a receipt stating this was a free service to replace the wrong fluid used( make them add a slip # from the 1st visit ). See if the correct fluid helps?
You should also know right now you will NOT get a brand new/rebuilt transmission out of this. The vehicle is too old for that. At best you will get your transmission repaired or a used one of the same age and mileage. Just how it is. Now ay in hades you get a new or even rebuilt trans out of this on that old of a vehicle.
It will cost you a lot of money and time as well to take this to court. Going to court should be your last resort option. Give the place a chance, and then give them a couple more if needed, to make it right before going off the deep end and heading to court. Be persistent but polite and document everything.
Again I say stop driving it and deal with the issue. The more you drive it, if this is a fluid caused issue, the worse you make it and the more of the blame falls on YOU!
