1. Trasmission slipping every once in a while. Possible cause, black fluid, almost 90K miles and it's worn.They tried a fluid and filter change. Didn't work but I knew it was a 50/50 chance. "A" for trying.
2. Change oil and check for a leak. Oil was changed but no leak was found. They even power washed the engine looking for it. Didn't find it but we'll keep an eye on it and bring it back for an inspection in a few weeks. Great effort trying to find it.
Only one problem but no big deal. When I checked my fluids, I noticed that the windsheild washer cap came off and some of the dirty water got in the resevoir. Other than running the pump for a few minutes and adding some cleaning fluid, no problems. All in all a great experience and I would trust them in the future. They didn't try and sell me anything I didn't need.
