Proper way to shift on a eaton fuller 8 speed

I could not tell you what gear to be in. But if I had to make a wild guess you will be right about either 4th low or 5th high. If that thing lugs on you downshift one. If it happens to be too much rpm, ease in clutch and take the next one up.

MPH is one thing. Your engine is the most important during shifting. The tach and behavior of the truck will be more important than MPH.

Don't sweat it. Two fewer gears will actually be a benefit to you, they will be more room between shifting, if that makes sense to you.

 

High side of 5th gear. Where 7 would normally be in a 10 speed.

 

Not much difference between an 8 or 10. Google the 2 and see the shift patterns. 10 you button hook back to 1 position with a range into high. 8 you don't. At one time there was a 8 sp direct with no range selector.

 

Also the granny gear has a high range. It's kind of like 4.5 gear. You go from 4th gear, range select up and go into lo high. Like 6th in a 10.

 

I had an 8 speed in a fleet truck.once and loved it .

 

Don't You split from 4th to go 5th on a 8 speed? And 5 split to 6th on a 10?

 

I don't remember ..Been many many years ago ..sorry .

 

10 speed yes, you split and then come across the box into the spring for that 6th from 5th low. Most newbies get thrown off because to them it's so far across the box and then they have to put it into where their right front jeans pocket would be.
