350Z: Auto Trans, Manual shift doesn't work
I just bought a 2003 350Z. The manual shift of the AT doesn't work. It will shift down but not up. I would like to know how this thing works. Is it just a switch closure that tells the car to shift or is it mechanical?
Any help or link to how it works would be greatly appreciated. |
Somewhat of a guess but maybe electronic issue in the JATCO TCM.

Good article but says a reset is turning the key off for 10 seconds and then back to the on/run position. Seems like it would reset every time you turn the engine off. Am I missing something?
|
more then likely not having trouble to get it to load but most of the time if it has a time limit such as turn it off for 10 seconds then back on then it has a limited window where it is keeping track of time and only does it in that window. that is done for the specific reason you say so it wont reset everytime
|
Not really acting like any scenarios in the article either. Car goes in all 5 gears. The only problem is the manual shift mode and it only won't shift up. Its shifts down fine. I figured someone on here would know how it works.

Simple - but did you check the fluid level?
|
Do you know how to check and make sure your servos are making good enough contact to activate? If not, I can post some pictures on how to remove the shifter cover and check the servos.

Do you have a OEM shift lever or,has a aftermarket like a Momo been installed?

Check for codes and check the fluid level. Manual mode will not work if there are certain faults in the tcm.
