So I have a problem. I drive a semi for 8-14 hours a day and I am finding myself shifting without the cluth. Even though I don't grind, is it still bad for the synchros?

 

If you can float the gears without crunching in this gearbox, you're probably not working the synchros all that hard!

 

^agree but i would TRY to remember to use the clutch but if your not grinding you can't b doin toooo much damage...

 

The syncros will resist you putting it in gear if you push them too fast they will tell you.

 

I don't shift fast when I do it simply because I don't shift too fast in the rig either. The synchro's just work for a sec and then it falls into gear... I just wanted to make sure I am not damaging it since I have a very difficult time when I drive a rig around for 10ish hours and I only spend maybe 20 minutes driving to/from work.

Thanks for the swift replies everyone!
