91 GC did something strange today

This caravan just had a trans rebuilt about 12K miles ago. Couldn't be
running better until this morning. It sat out side all weekend and
this morning was in the single digits. Got in started it, waited about
20 seconds and it wouldn't go into reverse! I mean you could shift
into reverse but the car would not move. I let it warm up for 15
minutes and everything is fine. Any comments on this?

 

My 95 GC SE did that once, a cooler line leaked and the fluid was low. I
figure as it warmed up the fluid expanded enough to let the pump get a full
column of fluid and allow it to work normally. A quart of +4 and a clamp
tightening fixed it.

 

Nope, no leaks. Full, clean, +3 fluid. It was colder than a biotch
this morning (4 or 5F). The cold definitely had something to do with
it. Like I mentioned, trans was rebuilt and was running great. This
morning was the first time it did this. After warm up and for the rest
of the day, no problem at all.

 

3-speed or 4-speed automatic? My old 92 with the 3-speed used to do that
occasionally, but it was going into drive (I always backed in and pulled out
in the morning). When it would do it, if I put it into neutral or park and
revved the engine a few times, let it come back to idle and put it in gear,
it would then grab gear immediately. It did it more frequently in its later
years (nearing 200k miles), but I might be able to count with both hands
full of fingers the number of times it did it. Always on a cool morning
start though...

At 204k the transmission bit the dust...it's in the driveway with a for sale
sign...and basically no interested buyers. I'd still love to fix it if I
could justify the $1300 rebuild cost...
