I used prolink uktra snapon scanner and the code was crankshaft position sensor I erased the code but come right back I gonna replace it but I want to know if changing the sensor will fix the problem thanks for your advice
Technician: Andy, Truck Diagnostic Technician replied 4 months ago

Your tranny needs to see input rpm in order to make a shift . It may rely on the crankshaft position sensor for this . I would replace the sensor and see how it goes from there .

I would think it will likely repair the issue- Is it possible the sensor got damaged during the removal and installation of the tranny ?

the was not damage during the removal cause checkengine light was already on second turbine sensor work so there is input pressure coming but I think the computer do not ready it cause crankshaft sensor block the signal I don't known if the computer need reprogram or not

If nothing electronic was replaced ( ECM or TCM ) , then there should be no need for programming at all .
