Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hey there, thanks for the question.
This is generally caused by either the solenoid failing, which requires a new valve body.
or when there is cross contamination with the transmission and radiator. Did you check the radiator for a pink froth?
It's not mechanical, needs a new control valve assembly. The control valve is pretty easy for any transmission repair to replace but the price for the part is very high, its about $900.
and just so your not confused. The control valve is the valve body assembly with the solenoids that I mentioned in my initial response.
You could always attempt to just replace the solenoid itself, which requires some VB dissasembly, but you risk it not correcting the issue. We ALWAYS replace the entire control valve to make sure.
if you need further help let me know please, if not please be sure you leave me a kind rating. It's the only way the site will credit me for my time.
