I burned 3 gallons with the stock S-25 and one gallon with a Picco 26. The last time I had the truck out I noticed that it would not roll backwards with the engine off. When I tried to push the truck backwards the wheels locked up. I put the truck on a box with all 4 wheels off the ground and tried to spin the spur with the motor off. I felt major resistance when I tried to spin the spur. I tried spinning the spur in both directions and felt resistance both ways. I pulled the motor and I still felt the same resistance on the spur gear with the motor out. I knew that there was a problem with the transmission so I pulled it. I found problems inside the transmission.
The second gear clutch arm wore into the plastic around the second gear engagement pin. This forced the pin towards one of the screw holes that retains the metal clutch holder plate. The screw hole broke and the screw and metal clutch holder plate were coming off second gear.
The loose screw and clutch holder plate were wearing into the transmission case. There were bits of plastic all inside the case.
Transmission parts
I need a new transmission case and a new second gear.
The teeth on all of my gears look fine. My reverse module is also in good condition.

Were you slamming back and forth between forwards and reverse? I was just wondering what caused the premature failure of the tranny.
