I have p1870 transmission component slipping code showing. Doesn't slip bad though. I was reading up and some were saying possibly torque converter acting up locking and unlocking. I was also thinking of a throttle position sensor going out
Yes when it jumps up and down it will***** a bit. Gets very frustrating driving on highway
That leads me to believe the trans isn't the problem. Try having the computer scanned for trouble codes. Most parts stores will do it for free. I think it may be engine related. Also, check to make sure the trans fluid isn't burnt, low, or really dirty.
Only codes present when scanned was the p1870. Transmission component slipping.
I need to check the fluid. Possibly low. I also have a bad thermostat that im going to fix would that have anything to do with the lurching? Being that the engine is not getting to normal operating temp?
