Eaton 10spd splitter procedure

Why would you be going into low at 60?

 

10 speed except super 10, do not have splitter. Only range, which you should be under 20 when going to lo range.

 

The range selector only shifts while in neutral, you will not hear the transmission shift (clunk) while in a gear. IMHO, it would be foolish to play the the range selector at high speeds.

 

Never tried it and ain't gonna. You could seriously damage the synchronizer and sliding clutch doing that.

 

Only when you move the stick to neutral.

 

I sincerely doubt you could put it into gear at that speed. The high low won't engage until you go to neutral. If you wanted to, you could ride down the road all day long flipping it up and down and nothing will happen until you take it out of gear.

 

Yes, out of gear is what I thought he was talking. Just range shifting in neutral at high speed can definitely cause damage.

In gear, no. There is a detent spring and pin in the slave valve that keeps air from moving unless the shift forks are in neutral

 

There's an interlock on the range of every Eaton-Fuller transmission I've encountered so far. Unless the shift rails are in neutral the air should be blocked from going to the range piston. That's why preselecting a range shift is no big deal.

You can try it with the truck shut off. Put the stick in any gear and cycle the range lever, then move the stick back to neutral and you should hear it complete the range shift.
