Twin disc oil strainer should be cleaned every thousand hours of operation. offering services in Santa Barbara Harbor, Ventura Harbor, and Channel Islands Harbor Transmission noise is most commonly caused by a poorly running engine or a worn-out drive/damper plate. A compression check is a must before putting any blame on the transmission. If compression is not within 10% in all cylinders, uneven firing impulses may cause the transmission to make backlash noise.
If the engine is tuned up and running well, the drive/damper plate may be the cause of noise. This plate absorbs the engine’s firing impulses, is the last link between the engine and transmission, and connects directly to the transmission’s input splines. With a bad drive plate, even the slightest variation in firing impulses from the engine can cause transmission noise.
Noise may be more apparent at idle, since the engine firing impulses are further apart. Avoid idling for great lengths of time as this puts extra wear on the transmission. Transmissions last the longest at steady cruising speeds and with no high rpm shifting.
