I got a code 12 a 45 and a 55 , I know what the 12 and 55 is but whats a 45?

 

Direct quote from my Haynes Manual:

" code 45. Overdrive solenoid. Problem detected in the overdrive solenoid circuit"

And something to note is that Cardone says ECM/PCM failures are most likely caused by problems in the tranny's solenoids.

 

Wow I didnt even know this van had overdrive...lol ..I got this van with a rebuilt motor.

 

Hey that wouldn't cause the van to just "shut off" would it ?

 

No it wouldn't. If you don't have an engine code for the stalling problem, i would ck for fuel pressure and flow.

 

First, I am no tranny expert.
You might not have overdrive, but may have a lock up torque converter.
I could imagine that this converter locked up, would stall the engine when downshifting/ coming to a stop. but,
A TCC solenoid circuit would be a code 37

 

You are right. But with code 45 3/4 shift solenoid no rpm drop. this tell me the torque converter is not able to lock up, because of no rpm drop. 3-4 SHIFT SOL, NO RPM DROP @ 3-4 SHIFT TC-165 45 A5 P 0783 or P0740.
If the torque was locking up and causing a stall problem. The engine may stall as soon as the shifter was moved in drive or reverse. If you would like a copy of the test 45 on pdf file, just send me a pm, with an email address to send it too.

 

thanks
