1999 Plymouth Grand Voyager transmission issues

While my wife was driving our van the other day, the "Service Engine Soon"
light came on and the transmission started shifting weird. Well,
basically, it is shifting from second to third at higher RPM's then
usual. Nothing into redline or anything, but obviously there is something
wrong.

The tranny fluid is at normal levels, is clean, and the vehicle seems to
drive normally. Would it be a good guess that some sort of computer
module is whacked (one that, perhaps, controls the shifting) and needs to
be replaced? And, if so, anyone have any idea what this will cost to get
replaced??

anytime you get a check engine light, go to the nearest autoparts store
(that primarily sells retail) and see if they will check it out. Most big
chains now test for free then look up the error code and try andsell you a
part. At that point tell them you need to think about it and post the code
here.

Then someone will look it up and provide a little better answer to your
problem.
BTW I use alldatadiy.com for the online manual and code help. worth it IMHO

I ended up bringing it into the dealer. It was speed sensor module (or
something similiarly named). Cost $150 to get replaced. (considering the
thousands of dollars I've been shelling out for my 1996 Dodge Stratus
lately (head gasket, cracked exhaust manifold, cat converter, water pump,
etc, etc), seems like a good deal.)

This is the same problem I just started having with my 1999 Grand
Caravan...I hope it is the same with me as it was with you. Thanks for
letting us know.

I just repaired a 1998 van with the same problem.When I scanned it I found
a shift error code.That doesn't pin point a bad part or anything.Most
parts stores would scan it and not know which part to sell you, so thats
not the best method of trouble shooting.After driving the van and watching
the data stream I noticed the input sensor acting erratic going from zero
rpm and back up to engine rpm back and forth.I replaced the input sensor
which is directly on top of solenoid pack.(would be on front side of
transmission when tranny is in the van.) A 1 inch socket removes it. After
replacement the van worked perfectly.Just something you might want to try.
