When I received the truck, it had a 46 216 engine with a 4 speed transmission (no idea what that year was). The clutch fork to pedal link was never there, so I had to coble something together. I also replaced the engine (216 was totally rusted out) with a 55 235. While I admit that I do not know what to expect from the transmission, having never had a transmission without synchro in at least first gear and hydraulic clutch, shifting this truck seemed awfully rough - a lot of grinding gears. Any suggestions - even the most obvious would be welcome.

If grinding gears, clutch might not be fully dis-engaging, can first or reverse be engaged at standstill without grinding? If so, then synchro might need replacing. Remember, this is a truck transmission, does not shift fast, gently push and feel the synchro click in.
