I am thinking of installing a bypass filter for automatic transmission oil. Will the bypass filter help stopping or preventing transmission slipage? What are the causes behind the slipage?
No, an almost new transmission may fail for many reasons. Factory defective parts. Slipping, soft, shift flare can be caused by how the clutches are operated as well as the clutches themselves. It was pointed out earlier low line pressure is frequently a problem, and could be caused by overheating the seals.quote:

Driving conditions have no effects to the clutch wear at all???
Well ..sort of. The older automatics (the only thing I know =dam/n reliable), to allow a "smooth" shift, would start disengaging one applied element (either a clutch or a band) while actuating the next in the shift sequence. This could be called slippage but you'll notice that your tach, if you have one, doesn't indicate that the engine sees any "runaway". That is, it doesn't slip ..but the opposing forces of band/clutch application (one losing its grip as one is gaining it) DOES wear on components. They all shed metal and friction material.quote:
Doesn't AT nomrally slip all the time during gear shifting?
