yes check you vacum line in the back of your transmison
might be vacuum linkage, maybe low on trans fluid, computer
No, but it can cause the trans computer to not be able to communicate. that will cause not shifting.
best case senario, low trans fluid. worse case senario bad transmission.
Is there park and nurtural?
I'm having the same problem with my trans. I've read online that these trans have a lot of problems with the input and output speed sensors.
it probably needs a tune up an a intake system flush.. an as far as hard shifting if its a automatic you more than likely need to change the filter an fluid in the trans
Newer models like yours do not have a modulator on the trans; they are computer controlled. If you are having shifting problems I would suggest you change your trans fluid and filter; that should clear up shifting problems if it seems to stick in a lower gear. I hope this helps you. Mark

A "speed" sensor can affect the shifting of the trans.A "speed" sensor can affect the shifting of the trans.
A seal is going bad, trans will need a overhaul.
If the trans has quit shifting, it is because the computer has detected a problem and set a code. Have the system checked for trouble codes.
The speed sensor needs replaced. It is on the trans.
