Hi All, I had a CEL a week ago P0441 which is basically a bad n80. I did not have any issue when CEL came on but a couple of days later my car won't shift to high gear on low speed (like when its on auto). The car starts to shake and the rpm needle fluctuate, goes down and back up few markers. I did full my tank to the max couple of time accidently.
I switched it to tip and started changing the gears manually and saw that if I change it around 2.2rpm it shifts smoothly. But if I change the gears faster like low speed high gear it starts to shake and also if I go more than 2.2rpm. Also when the car starts shaking the CEL starts blinking. I have to buy a obd scanner any recommendation for it? last time I borrowed it from a friend and it gave me that error. I have yet to get the new error codes out of it but I am pretty sure these symptoms can pin point the issue.
I replaced n80 last night and the problem is still there.
