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 from lunch. It wasn't on this AM on the way to work, nor was it on last night.

The code: P0783 - 3-4 Shift Sol / No RPM Drop at Lockup

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....

Thoughts??
