Reasons why the automatic transmission oil pump bushing rotates:
1. Lack of lubrication:
* Low automatic transmission fluid level
* Contaminated automatic transmission fluid
2. Bushing wear:
*Normal wear and tear over time
* Excessive load on the bushing due to high viscosity of automatic transmission fluid or pressure problems
3. Problems with automatic transmission fluid pressure:
* Faulty pressure regulator
* Clogged oil filter
* Automatic transmission fluid leaks
4. Problems with the pump:
* Wear or damage to pump gears
* Weak drive chain or belt
Symptoms of a rotating automatic transmission oil pump bushing:
* Reduced automatic transmission fluid pressure
* Automatic transmission overheating
* Slipping or hard shifting
* Automatic transmission fluid leaks
* Extraneous noise from automatic transmission
Consequences of a rotating automatic transmission oil pump bushing:
* Damage to other automatic transmission components, such as planetary gears, clutch packs and bearings
* Loss of lubrication and accelerated wear
* The need for expensive overhaul or automatic transmission replacement
Solution:
* Check and, if necessary, add or replace automatic transmission fluid
* Replace worn oil pump bushing
* Diagnose and fix problems with automatic transmission fluid pressure
* Repair or replace the faulty pump
* Regularly service the automatic transmission and change the fluid and filter
Prevention:
* Regularly check the level and condition of the automatic transmission fluid
* Change the automatic transmission fluid and filter in accordance with the manufacturer’s recommendations
* Avoid automatic transmission overheating and overloads
* Use only automatic transmission fluid recommended by the manufacturer
