over under problems with my eaton

Eaton Service Manual

A couple things... this manual shows only the RTX, not the RTO, at least in the list on the cover. The only difference is in the main box shift rail setup, so no worries there. Also, are you even going to use the DR gears? They are largely superfluous on-road.

But first check needs to be the air supply, a dirty filter can cause this by limiting the force applied by the actuator as it moves.

Good Luck!

 

Air supply...or perhaps this:

I just had my servo piston assemblies replaced on my Eaton 13speed.
They are like $20 in parts.
My issue was sluggish shifting Hi/Lo range or into Over.

Never had any grinding though...

 

I have the same tranny except a direct, no O.D. Mine did not split real well the first few weeks after it was rebuilt, but has worked itself in now and splits great. I would guess yours is an air supply issue, or maybe a sticky valve. I would pull the filter out of the regulator on the back of the trans and see how it looks.


Heres what it looks like, exept it's upside down in the pic for some reason.

 

Mine did that, took it to mech it was syncronizer on the bull gear (and the bull gear was nicked up pretty bad).Parts and labor about $350.00 give or take.

All you tranny parts here, for every Eaton tranny out there!

 

Hi, I have FRO15210C , air is leaking on top of the transmission by the shifter.
I changed the oring. I saw a pink air line and unhooked it and the air went to normal, but every time I reconnect the line the air goes down and the high and low won't function.

Any HELP Please?
Thank you.

 

Fro has module on top I believe but the range selector is under top plate. If you get water to that cylinder it will corrode and stick.

 

maggard is correct. You have to have the top plate removed and the selector is easily rebuilt with a kit from Eaton. Any reputable transmission shop could do it in a couple of hours.
