Air leaking from the top of a 10 speed Eaton fuller and how to repair.

Thank you so much having that very problem right now

Thanks for great explanation and video
I don’t have air leak but I have transmission fluid leaking around module and shift tower
Should I replace top plate or just gaskets

First off let me thanks you for taking your time to upload this video!!! But i have an issue where when i switch for high to low i get a short grind noise. But if i wait a bit at a complete (let the trans stop inertia spinning i guess) stop it doesnt grind. What might you think it could be please sensei

My FR 10 speed completes range shifts upwards perfectly, but the range shift to low seems to be a bit lazy. When you go from high to low, you have to Rev-match before the range shift is complete. It’s like the front box goes into gear before the range box. If you are lazy when slowing down and don’t catch low range by giving the throttle a blip, it won’t catch the low range and just stays in a neutral state.

All the older roadrangers I ran didn’t do this. Is this a problem or a nuance of this trans?

Awesome videos btw!!!

Seems like the manufacturer should have used a thin plastic sleeve in there knowing air components are susceptible to water condensing and rust

Will this cause slippage like the clutch is slipping?

Do you have a video of building the plate?

Thank you!!!

Thank you

My transmission leaks oil from the breather when I up the converter in high gear, what can cause it? It's a 10-speed aeaton

What would be the problem if it doesn't shif from high to low or low range to high range
Thank you

How much does it cost to replace it?

good video my friend ....very clear ,well explained.

I got the issue once again Ive already had the plate replaced and less than a year it’s leaking air from the piston seal again..Also have had a new air dryer put on but it seems there’s still excess water in the system that causing this problem..🙄

What’s average shop charge to customer to do this job?

Awesome video - now I know how to fix an Eaton Fuller gearbox :)

I have a 2013 freightliner cascadia. When I flip the splitter on the high side I hear air leaking inside the cab. With the splitter in the down position there are no air leaks. No air leaks on the outside of the cab either.

How much a top plate cost for a Eaton 10 speed

So I have a 1980 S1955 with a 10 speed . I busted the hi-low air line on the stick. While looking for a replacement they are selling "Upgraded larger diameter air line kits"

My question is this.. is it necessary. And will the kit have the fittings that will match the block that is on the shifter and the fittings on the modualtor?

Any help would be appreciated. Thanks

What if I spray soap mixture on the modulator and it’s spewing bubbles all around it and where it connects to the top plate ? Doing it when it’s in high and low split

A good reason to take care the air dryer and drain the air tanks. Thanks for your explanation!

Where can I buy a new top plate

Brother that is a good video thank you! Great explanation. I had similar problem and I bought the the ' Fuller Range Piston Kit' part# K2923. But most of the time when I come to a stop and I flip the high range to low it won't click. Have to put in high again and low and then it goes...also when Iam down shifting and go from 6th to 5th gear it grinds and Iam bugging to think is either the piston shaft itself with its seals and O-ring or is maybe time for me to buy a new top plate.

What do you think I may need to do or buy?

Thank you again 👌
