Question about Cars & Trucks
Car has 138,000 miles-just bought 4 months ago. About two months ago I had the trans fluid and filter changed. They also added "lube guard". The trans has worked perfectly till today. I got in, started to take off and major slipping occurred. I pulled over on a side street and stopped. Then backed up in reverse. I then went back in to Drive. It worked fine then. I did some errands and just before getting home, seemed to start slipping again. In the middle of this I accelerated heavily and was like nothing wrong. This came on on all the sudden. I checked fluid level and it is correct. I am to go back to the place that did the fluid change for evaluation. Anything that I should know as it worked great then nothing, then great again. Thanks so much for any advice or help. Rick

is this car still under warranty? if so take it back to the dealer and don't accept it as repaired till you drive it. sounds like the logic that controls the transmission is flipping out, sometimes they will tell you that it needs a reflash. what this amounts to is that the manufacturer put some not so great programming in the logic when they built the car but now they have a patch or fix that makes it work better but you have to pay them for their time to install the fix. ask them what they will charge you for the privilege and decide if it's worth it to you. there is a recorded technical service bulletin about harsh shifts for your car. well, actually there are two, the latest one a revision of the first. i would try to make this their problem, it really is. hope this helps.

But I am afraid I can't tell you want all these codes mean for your car. It was probably not related to the change in fluid that was performed. However, it is serious and should not be driven until fixed. Risk of total destruction of the transmission is too great. I would assume the symptoms are so diverse that it may be a bad transmission control module. Which is about $200, and fairly easy to replace:
But there are other possibilities, such as a bad relief valve could be letting main pressure drop too low.
This is the type of thing which does require an expert and can't easily be done remotely.
