Transmission retarder found a part
Today I was removing the hydraulic hose from the Allison transmission to the retarder after all the transmission oil run out I put floor dry to clean the oil and I found this rubber looking part. It look like a plunger and I think it came out of the hose on the retarder side of the hose ?? Since I hadn't removed the hose on the transmission side or maybe it was just mixed up in the floor dry has anyone ever seen this part
