The automobile fault code P2831 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops. Therefore, the total cost of fixing the P2831 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P2831 code refers to the shift fork ‘A’ position circuit in the transmission.

The transmission has two electric motors that shift the gears. One motor is for gears 1-3-5 and the other is for gears R-2-4-6.

The motors are integrated into the Transmission Control Module (TCM) and work independently. The gear shifting is made by two shift drums connected to shift motor pinion via two ideal gears. The maximum shift force is 1500N (337 lb).
