I just changed the pressure, shift and lock up solenoids on my 99 s80 t6 and the service transmission message is still on. When I checked the codes the first time the solenoid codes came up saying something was wrong with the parts I just replaced. Then I drove the car around the block and it went into "limp mode". I cleared the codes and drove it again. This time it drove fine but the service transmission message came up again. My question, is there a procedure that you have to do to "teach" the computer the new parts and then the message will go away or do I have to take it to the dealer and pay another $100 to clear it or get a computer update?
Thanks for your time.

It won't learn, it needs to be reset and that is assuming that you corrected the problem and that there's something else not impacting the transmission that is showing a by-product code.

 

Ok. Can I reset it with a generic code reader or does the dealer have to do it?
Thank you for the last post.

I don't think this is something that can be done with a basic code reader.
