My tranny will not shift into drive or reverse all the time, only when it wants to. I know it is not the tranny itself, it has to be something controlling the tranny. I changed the computer and also hydraulic/electrical module on front of tranny with junkyard parts. Maybe I got bad parts from junkyard?.. Could it be a clogged filter? Ed from Minnesota Thanks
Sorry Ed. I can virtually assure you that if you changed the computer and hydraulic pack and nothing changed, that it IS the tranny. In fact I think your lucky that you didn't make it worse.
How many miles on this van?
I have a 94 T&C myself and the transmissions in those vans started out really terrible in 1990 and got progressibly better over the next decade - as Chrysler learned from their mistakes and redesigned parts. In fact the A604 transmission in a 2001 minivan is almost a completely different animal than in your van. For one thing the mechanical linkage is gone.
You can try a COMPLETE fluid and filter change but I think your tranny is just simply worn out. But you are lucky that it is still working since that means the gearsets and case are still good and a rebuild by a competent rebuilder would put it to rights.
You can try having a Chrysler dealer scan it with a scan too and tell you the clutch volume indexes - if they are out of range the transmission is worn out and needs rebuilding.
LGR, give the guy a break. Sure he's a stupid shotgunner who deserves what he gets, but your getting just plumb rediculous. The MAP sensor is only used by the TCM to modify 2-3 and 3-4 shift hunting on grades.
The tranny on that year will shift into reverse even if the TCM is blown. It's part of the set that is actuated in limp mode.
