What kind of transmission does an Infiniti have?

This is a common mistake that happens during various repairs. Front-wheel drive Infiniti vehicles with 5 speed automatic (AW55-51SN) transmission can suffer from harsh and delayed gear shifts between all gears. In most cases, the car will run fine while cold, as this problem will show up after warming up.

What to do when automatic transmission won’t shift into 3rd gear?

Check the Throttle Cables. Changing the fluid solves plenty of transmission issues but if the problem of automatic transmission won’t shift into 3rd gear persists, the parts you should check are the throttle cables.

What causes a bad speed sensor on an Infiniti?

Faulty Vehicle Speed Sensor – If your Infiniti has developed a harsh shift or is stuck in emergency mode (limp mode), the vehicle speed sensor (VSS) may be the problem. Sigan from the VSS is sent to the Powertrain Control Module (PCM), and the last of the signal can cause one or more of the previous systems.
