I found a 500 page progear manual online. Any reputable places to source parts?

Thanks. So what in the hi-lo box starts to go? Is it somthing that can be caught and dealt with early after indication? Whats the tricky part to these rebuilds, finding parts? Appreciate the advice.

Hauled 14 tons this afternoon on the highway and started noticing a whine coming from, what I assume, to be the transmission. The truck had trouble going into Hi, and noise was more pronounced in 3rd gear. What are some things to rule out and figure out how much this will cost? Synchro, shift cylinder, solenoids, shift fork, hot oil, differential noise disguised as tranny noise? I feel like it is odd to have issue more prominent in 3rd. Could this be diff noise traveling up drive train? Does this sound like a tranny swap is in order? What does a tranny repair look like for these units? Can these be swapped with an Eaton? Thanks for your knowledge, time, input.

I'll have to look. Truck is offsite today. My assumption is yes, but will veryify the end of the cable when I get a chance. Appreciate the input greatly.

Hard to say, there are a few gremlins to work out. The speedo connection is flush with the block, so I believe it must have sheared/broke durings its life.

Appreciate the responses. I'll take a look at tach situation...should have thought of that. How is it supposed to attach? It looks sheared? Any issue getting dirt in there if left removed? Usually shift with a bit of finesse and the ears anyways...

In front of the fuel pump, passenger side, on base of block, behind radiator fan, is a hole..that spins with engine running...obvious oil weep coming from the area. What goes here? Recently bought Mack truck for a workhorse. Trying to make sure she runs, and continues too.
