hello everyone ,
I recently bought a truck sight unseen - too late now to be regretful- took the truck on the highway and it seems like 4/5 and 9/10 gears has switched places though Eaton fuller online manuals show that this model has no U pattern but H pattern , so in shot the 10 gear is towards the dash 9 gear is towards sleeper . No grinding and pulls out ok . So is this normal or what could be the problem?
Thanks

Somebody probably just changed the shift bar assembly from the H pattern to the U pattern. Its impossible for gears to switch places like that without changing the gears inside or changing the shift bar housing.
Dino soar, yazied and BoxCarKidd Thank this. -

I think that if 10th gear is forward toward the dash, then the transmission is an overdrive.
In 9th gear, toward sleeper, the trans would be in straight through mode, direct drive, from the front shaft to the yoke.
At least that's the way it works on my RTO 14715. I believe the "O" in the RTO is for overdrive. -

I don't believe that the FRO series transmissions share a top plate with the older transmissions that would allow high to be against the dash.
It sounds as though it has had the transmission changed, crawl under the truck and see if the tag is on it still. -

Maybe somebody flipped the gears to make it a double Overdrive.
I'm sort of kidding. People used to flip them on the older Transmissions. I wonder if that's possible on a newer transmission.
Edit:
that probably doesn't make sense because the shifter itself is made to retain the normal gear pattern. -
The double over moniker comes from there actually being two OD gears in the trans, one in the main and one in the auxiliary, so if you ever hear of someone talking about a double over 9/10/15 speed, they are full of crap. -
How about that? I meant to say overdrive and I said double...
Brain fart....
