Hey guys, today I got my ODB2 code reader because of an engine light that has been coming on and off for a while now. The code is for something with the transmission but it shifts fine, accept sometimes when I'm shifting myself it will sometimes take control back and start shifting for me as if I had it in C mode. I still need to get my tranny fluid changed and I'm thinking of changing the solenoid as well but could this be a bigger problem? How worried about this should I be. I cleared the code and it hasn't come back yet but I think it will with a bit more driving so is that a symptom of a sensor or something that has failed? All feedback is appreciated.
