manual T444E gear slipping

[LPTC]

Hey guys,

Wondering if anyone can offer me any advice. Our bus has been on the road for about 4 or 5 months now on the West Coast and is due for a tune up which we are right now working up some money for...

Main problem we are looking to get checked out is that 4th gear slips out whenever you let up on the gas and grinds. The quick fix is that you hold the shifter in place when you are in 4th gear.

Maybe unrelated but 2nd gear is really sticky and sometimes feels like it needs to be forced. Not sure if there is anything we may be able to do before we take it in to the mechanic.

Well, you could check the gear oil level for starters.

Just a wild guess here, but sounds like the trans is due for an overhaul. I'd guess the 4th synchro is shot, possibly the shift collar too and maybe the gear itself. 2nd might be the same problem, or it might be binding in the shifter housing itself.
It'd help if you have the trans model # to give us, That'd tell if it was OD, single or twin countershaft, etc.

Your 4th problem is most likely the 4-5 synchro being worn out. 2nd is probably in the shifter rails or housing. I don't know know about you but those things are stuff that is out of most peoples repair range. If you got the space, tools, and the ambition, take it out and get it apart. That's the only way you're going to tell for sure.
