Turned the automatic transmission oil pump bushing: causes and consequences
A rotating automatic transmission oil pump bushing is a serious malfunction that can lead to catastrophic failure of the entire transmission.
Reasons for turning the automatic transmission oil pump bushing:
*Low transmission fluid level: Not having enough transmission fluid to lubricate the bushing can cause it to seize and cause premature wear.
* Contaminated transmission fluid: Dirt and abrasive particles in the fluid can cause scoring on the surface of the bushing and its subsequent turning.
* Worn high pressure pump: A worn high pressure pump may not be providing enough pressure to properly lubricate the bushing.
* Defective bushing: In some cases, the bushing itself may be manufactured with defects, making it more susceptible to turning.
* Excessive pressure in the automatic transmission: Excessive pressure in the automatic transmission can overload the bushing and cause it to spin.
Consequences of turning the automatic transmission oil pump bushing:
* Oil starvation: A loose bushing prevents the oil pump from providing the transmission with sufficient lubrication. This leads to oil starvation, which can cause serious damage to the internal components of the automatic transmission.
* Automatic transmission failure: If the oil pump cannot provide sufficient lubrication, the automatic transmission may fail, requiring expensive repairs or replacement.
Repair for a rotating automatic transmission oil pump bushing:
Repairing an automatic transmission with a rotating oil pump bushing usually includes the following steps:
* Removing the automatic transmission: The automatic transmission is removed from the vehicle for disassembly.
* Bushing replacement: The damaged oil pump bushing is replaced with a new one.
* Inspection of other components: All other automatic transmission components are inspected for damage that could be caused by oil starvation.
* Replacement or repair of damaged parts: Any damaged parts such as couplings, pistons or gears are replaced or repaired as necessary.
* Thorough cleaning: The entire automatic transmission is thoroughly cleaned of dirt, metal shavings and transmission fluid residues.
* Automatic transmission assembly and installation: The automatic transmission is reassembled, filled with fresh transmission fluid and installed back on the car.
Repairing an automatic transmission with a rotating oil pump bushing is difficult and expensive. To avoid this catastrophic failure, it is highly recommended that you regularly service your automatic transmission, check the fluid level, and use only manufacturer-recommended transmission fluids.
