Hi all, my tranny has started hard shifting when Im in slow moving traffic mainly. Doesnt do it all the time but enough to get on my nerves. Has anyone heard of this issue?
Its in a shop now due to a crank module and ignition module issue and they told me about the shift issue coming up on their diagnostic.

Thanks

David

Well David, you have to start with the basics here. Just a few questions.

How many miles on the car?
Last Transmission Service?
Have you checked condition, level, status of transmission fluid following the instruction in your owners manual?
Are there any transmission related DTC'*? (Diagnostic Trouble Codes)
