Troubleshooting car problems of not working gear shift for automatic transmission 

When the Automatic transmission gear shift is not working this is a very serious problem that causes by several reasons and one of those serious problem is a completely damage transmission. However, it may also possible that the transmission problem only involves a very low amount of transmission fluid. You need to confirm if there is enough transmission fluid on the system but, if the fluid level is enough, then the possibilities is that the system suffers a bad fluid pump or Gear selector linkage problem.

You see, when an automatic transmission suffers with bad fluid pump all the gears inside the transmission will not work, because automatic transmission depends on the hydraulic fluid pressure that is created by the fluid pump to pump transmission fluid throughout the transmission assembly so that it will work properly.

Same condition with the bad fluid pump, when an automatic transmission has a problem on gear selector linkage all gears will not work. Gear selector is the one that determines which gear is going to operate. When a gear selector linkage is broken or out of adjustment it cannot operate properly causing the gear not to work.

Possible cause why gear shift is not working

1. Low transmission fluid
2. Faulty fluid pump
3. Out of adjustments gear selector linkage.

How to fix not working gear shift for automatic transmission

1. Low transmission fluid
Check the transmission fluid if within the recommended level, if the problem is low level automatic transmission fluid (ATF), just add enough amount of fluid this should fix the problem.

2. Faulty fluid pump and gear selector linkage
If the problem has nothing to do with the fluid level then have the car towed to a reputable repair shop. Ask the mechanic to inspect the fluid pump and the gear selector linkage, the mechanic will probably open up the transmission for better diagnosis. If the problem is not fluid pump or gear selector linkage, no other option but to replace the transmission assembly with a new one since the automatic transmission gear shift is not working.
