Once the leak has been pinpointed and traced to its source,
the cause of the leak must be determined for it to be properly repaired. For
example, if a case component is resealed but the mating surface is damaged,
resealing will not repair the leak. The damaged mating surface must be repaired
or replaced. Before attempting to repair a leak, certain conditions should
be checked for and corrected if necessary. The following conditions may cause
a transmission oil leak.
| | Important: The Suzuki 5-speed manual transmission does not use gaskets to seal
major case components. GM P/N 12346240, or equivalent, should be used where
applicable.
|
| • | The oil level is too high. |
| • | A plugged breather vent. |
| • | Improperly torqued fasteners, dirty or damaged threads. |
| • | Warped flanges or mating surfaces. |
| • | Scratches, burrs or other damage to mating surfaces. |
| • | Insufficient or excessive amounts of sealer. |
| • | Cracking or porosity of the cases. |
| • | Improper sealant used where applicable. |
| • | Scratched, nicked or damaged propeller shaft surfaces. |
| • | Loose or worn bearing causing excessive seal wear. |
