P283C Meaning

There are two electric motors used for shifting gears in the transmission, one for gears 1-3-5 and one for gears R-2-4-6. The gear shift is performed by two shift drums connected to the shift motor pinion via two ideal gears. The maximum shifting force is 1500 N (337 lb). The motors are integrated into the transmission control module (TCM) and operate independently of each other.

P284A Shift Fork “B” Stuck

Code P284A – Possible Causes and Solutions

Possible Causes:

  • Outdated transmission control module (TCM) program → Reprogramming required
  • Faulty transmission control module (TCM)
  • Mechanical issue in the transmission assembly

How to Fix Code P284A:

  1. Check the possible causes mentioned above.
  2. Visually inspect the wiring harness and associated connectors.
  3. Look for signs of damage: broken, bent, corroded, or pushed-out pins.
  4. Ensure the control module is functioning properly and up to date.

Possible Symptoms:

  • Illumination of the engine light (or maintenance warning light).

Meaning of Code P284A:

The transmission uses two electric motors for gear shifting:

  • One motor for gears 1-3-5
  • Another for gears R-2-4-6

Gear shifting is achieved through two drums connected to the shift motor pinion via two intermediate gears. The maximum force applied during gear shifting is 1500 N (337 lb). These motors are integrated into the transmission control module (TCM) and operate independently.
