Ok I am probably not going to like the answers I get but here is the lowdown on my 1999 WJ 6 cyl., 42RE Tranny.
Got an engine code today on the way back to work after driving a few miles to my home for lunch
The light wasn't on this AM on the way to work, nor was it on last night when I shut it down for the evening.
The code: P0783 - 3-4 Shift Sol / No RPM Drop at Lockup
My understanding is the OD solenoid doesn't engage and help the OD come on, therefore helping with fuel economy, etc... correct me if I am off base though!
Factors and history:
* Cold tranny doesn't smoothly shift into 3rd gear normally. Warm, shifts just fine. Was told that this could be a clutch pack issue.
* Used the Full time 4WD for the first time in the snow last night
* Light appeared shortly after going through massive amounts of flooding water on the roads.
What is the culprit?
a) The OD solenoid
b) The clutch which is now shot b/c I HAD to use the 4 x 4...therefore straining an already malfunctioning tranny
c) The Water impacting the solenoid, causing it to temporarily malfunction
Yeah I know I am clutching at straws with the last one, but I am desperate to NOT spend huge bucks....
Funny thing is? It seems to run and shift just fine. Is this something I should be able to feel?
Could this be temporary and the code gets flushed after a few cycles?
Any insights would be greatly appreciated.
