hello i replaced a transmission in my 2002 Nissan Sentra and i have a problem with the transmission and i got a code p1574 and the transmission only works forward and backwards and i know the transmission is good what can i do in this case thank you
-
Did you change the transmission with a used or factory rebuilt transmission? if you use a used was the transmission from the same year, model and trim? the code means that there is no communication between the transmission control module and the engine control module. If the transmission is from a different model or year, the control modules may not be able to communicate.

Hello my 2002 nissan altima is not shifting properly almost like a misfire shifting a little harder the. Usual i dont know which speed sensor i need to replace it showing me code p1574 ...any idea what i should do
?? -
I have a few questions to help diagnose the problem:
Are there any other codes?
Does the vehicle speed shows correctly on the speedometer?
What engine size is your Altima?
Do you have automatic or manual transmission?
That code shouldn't cause any shifting problems, the problem is either the combination meter or Vehicle speed sensor.
