You need to get to the transmission linkages with some penetrating spray, right where they are attached to transmission at front drivers side. You may have to remove battery & tray to get better access, but 90% of time that's the problem area. You'll see where the shifter linkages attach & pivot on top. The top linkage is your power valve,(like a kickdown) which kicks it down on acceleration, then returns after. This needs to move freely, and it may take some work & spray to get it loosened up, but that should help with your problem, as it affects the shifter itself too. After you get them movong freely, put a good coat of white lithium grease or similar on them . On my 95 neon, i'd have to do it, about once a year or more. Initially it would shift out of lower gear to next at higher revs, and when stopping it would shift down hard. Good Luck

SOURCE: transmition not shifting
HI. I would check the TCM(transmission control module), this device transfers the initiated actions from the shifter to the solenoids in the transmission. if the TCM is good, i would check the solenoids in the transmission pan to see if they are working properly. Depending on the model, your transmission may be sealed but, if it isn't, i would recommend checking the fluid level as well.
Please rate and have a great day:)

Try replacing the transmission filter and the trannie fluid. Mine would only go in reverse, and now it drives pretty well. This year has a screw on filter. Hope this helps

Sorry but if your reverse is having trouble you will probably have to replace or rebuild tranny like me. Otherwise try new filter and fluid first.

Tips for a great answer:
car not changing gears and not shifting out of park mode ,it can be shifter assembly issue, or it can also be
transmission issue. Get the shifter assembly inspected with ignition OFF.
