The automobile fault code P284A 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 diagnosis and fixing the P284A fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P284A code refers to a problem with the shift fork ‘B’ in the transmission.

There are two electric motors used to shift gears in the transmission. One motor is used for gears 1-3-5, while the other is used for gears R-2-4-6. The motors are integrated into the Transmission Control Module (TCM) and work independently of each other.

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).

What are the possible causes of the P284A automobile fault code that triggers the engine light or service engine soon warning light?

If you see the engine light ON or Service Engine Soon Warning Light, it could be due to the P284A fault code. The possible causes of this fault code are an outdated Transmission Control Module (TCM) program, a faulty TCM, or a faulty Transmission Assembly. To fix this issue, you need to reprogram the TCM and visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
