Hard shift in 1st in reverse
Hi im experiencing some shifting trouble but i dont know what the cause of it is. I have a 97 7.3 with a zf5 in it. Its only had about 100 miles put on it in the last year and a half so its been sitting. 1st gear and reverse are very hard to impossible to shift into when stopped. If i shift into 2nd i can quickly get it to go into 1st or R. I checked the clutch master cylinder plastic bushing that are known to wear out and it seems to have little to no play in it. What i did notice was that the pedalbox bushing has some play and when the clutch is pushed in the brake pedal will move out slightly. The truck used to be a plow truck or has been plowed with. This is where im confused if having been a plow truck could have caused extra wear on the bushing. Its a low mile truck with only 69k. My other thought was that could it be hard to shift because its been sitting for so long? I bought some lucas trans fix to add thinking that maybe this will help but i dont think it will help. I hope a synchro may not be going too. Please help any input appreciated thanks.

That Lucas stuff is most likely for automatics (and equally likely snake oil). If it shifts normally with the engine off, it's much more likely a clutch / actuation problem, NOT a transmission problem. Don't overthink WHY the pedal box bushings are shot. They're shot. Replace them and see what happens. You might still have an issue "downstream" (hydraulics, fork, etc), but start with what you know is faulty.

Update: New pedalbox bushings came in as well as the clutch master cylinder bushing that wears often. Everything came apart and put back together some what smoothly (lots of swearing involved). Truck now has 1st and reverse again! Also shifts much smoother into other gears while driving. Thanks for all of the advice everyone!
