94 Grand Cherokee 5.2L V8. ..If Cold, Tranny wont go into drive
Was just given a 1994 Grand Cherokee. V8 5.2 engine.
I live in the northeast so the outside temp dips down to zero
overnight.
I went to use it the other AM after a zero degree night. It fired
right up,
but when I shifted into drive, nothing. It behaved as it was in
neutral.
I discovered that after about 20 minutes of idling it works again. I
dont
make a habit of driving a vehicle ice cold, but this seems really
weird
to me. Especially the 20 minute wait. If there was a piece of
electronics
that doesnt let one drive the thing untill it's warmed up that would
make
sense, but that would account for five minutes not twenty.
Any Insight?

Most likely needs the transmission fluid changed - may even need it done
a couple of times or even flushed. I'd be changing all the fluids anyway.

Re: 94 Grand Cherokee 5.2L V8. ..If Cold, Tranny wont go into drive
That normally indicates a low fluid situation.
Hmmm..... You should post all the problems in one thread because they
may be connected.....
A stalling issue can be a dirty connection at the TPS which also
controls the transmission shifting.... This is located on the throttle
body.
All the low power computer sensor plugs and sockets can benefit from a
clean with a spray contact cleaner. Electronic stores sell this. It is
a cheap possible fix before spending money anyway.

Though the time you cite certainly points to a problem even getting
the transmission fluid to circulate at all, here's an idea -- the next
time you run up against that problem (by the sound of it, we're
talking about tomorrow AM), put it in neutral for 30 seconds or a
minute and see if your problem changes at all. "Park" circulates
transmission fluid through an abbreviated route, "Neutral" circulates
through the entire system...

Though the time you cite certainly points to a problem even getting
the transmission fluid to circulate at all, here's an idea -- the next
time you run up against that problem (by the sound of it, we're
talking about tomorrow AM), put it in neutral for 30 seconds or a
minute and see if your problem changes at all. "Park" circulates
transmission fluid through an abbreviated route, "Neutral" circulates
through the entire system...
