This develop last July 2017 going for groceries I lost 4th and 5th gear they were slipping hard I check the codes it came up shift solenoid B stuck in the open position did my homework online and do some research and came up with changing the shift solenoids with good ones and new fluid in a filter kit I did all that a few yards for my buddies repair shop the AT light come on and stuck me in 3rd gear again the only problem is this time shift solenoid B is no longer stuck in the open position it's telling me there are no codes and when I erase them the a t light goes out I'm able to shift from 1st 4th 5th gear all the way through 1 2 3 4 5 a few minutes later it slams into 3rd gear at light comes back on I clear the codes as I'm driving it flawlessly shifts into 4th and 5th gear again but only for a few minutes then back into safe mode with the AT light on. I do have another transmission control module which I have yet to swap out and see if it makes any change. And this point I'm thinking there's another sensor? Please help and thank you in advance for looking watching and reading.
