Allison Transmission Problems HELP!

[GSwaim]

I wasn't suggesting the buyer drain the whole crankcase but it's easy enough to drop just a quart at most from the engine and tranny pan wothout a complete drain. The engine would be the tough one since the drain plug would have to be substatuted until you finish checking the drain plug magnet. The Allison would be easy because dropping the primary filter only would maybe make you loose a gallon of transyn. The filter as Jon explained could be inspected for solids and a sample of the fluid could be analyzed for non metalic particles.

I had my codes read by Prevost prior to the purchase and both transmission and engine ran clean with the exception of an ABS fault. No record of any transmission problem or service were detected or ever recorded at Prevost. I detected a leak in the front seal of the transmission prior to buying so I negociated that the seller pay for the R & R of that seal after the purchase. Since the Allison shifted perfectly up to the point it was removed for a new front seal, I had no reason to think it was being blasted with metal shavings throughout the inside. Only a close inspection of the primiary filter and/or an oil analysis would have told the whole story.
