will that code make my cummins in first gear rev high sounding like it should be in second gear it wont go into second till bout 20 mph like if I get really on the pedal it goes quick but at slow speed it takes a while and leaving off pedal ust befor will go in the gear I have a ats tranny on my 99 cummins 6.1 yeah6.1 the motor was board and sleeved from 5.9to 6.1

 

Mine thru that code and would start out in second instead of first. Its easy to replace. Just drop the pan, drop filter. install the govenor pressure switch and solenoid at same time.

 

Now with a ats tranny I would have to go threw them to get the swith and soliniod and im throwinh now a tcc code u starttruck and start driving the over drive off light comes on then I got to hit button to go out but weird last few days light has not come on at all what u think

 

I'd call ATS

 

Yeah ill prob call tom thanks
