C6 Tree Farmer Power Shift Transmission Thoughts?

[eichenberg93]

We have a C6 Tree farmer. Right now it has a 4-53 Detroit in it with a 5 speed new process Transmission. For a while we have
thought about finding a power shift to put behind the detroit. The other day we found a complete setup that is for a detroit. It come
from a roller with 3-53 in it. It comes with everything (flywheel,flexplate, torque converter). It says on the tag it is a "Reverse-o-matic"
Did a little looking and it looks like it might be made by funk.

The question is if anyone has any experience with that make of transmission. And if they are a reliable unit. I know it will take alot of
work and modifications to make it fit but after running the jack with one in it. I Dont want to go back to a Clutch.... ;)

I have a C-7 grapple skidder with a 4/53 and a three speed power shift, motor and transmission has been rebuilt . Just my two cents the power shift is to slow second is about right third is to fast and first is a snails pace. Many times I thought about putting in a manual transmision so maybe I could pick up more gears that suited the skidder better for different speeds. Just my two cents  ;D. Good luck.

Isnt the transmission and transfer case one piece on your C7. In ours it has a divorce Transfer case. So in reture it would still have a Hi-Lo in it. So you would end up with 6 Speed. How does the 4-53 handle the power shift. The timberJack has a cummins in it and that has better torque at lower Rpm's.

I don't think it will be worth it, especially if it's not a bolt in unit.  If I want powershift I would just buy another skidder.

It sounds like a good plan to me. We do retrofitting all the time... U can't beat a powershift.

We already have one skidder with a power shift in it. The treefarmer is just a backup and for smaller jobs that it is not feasible to have the Jack Hauled. The transmission from what we can see will bolt right up. All that has to be done is all the linkages have to be updated.

I would say you are getting ready to open a can of very smelly worms  but then again Im not the greatest wrencher so good luck if you do it let us know how it goes as a side not I saw a decent looking 450 T J  on cr in west virginia with trans. prob that could b bought for about scrap price I would tend to go that route

Will the 4-53 have more beans than this transmission can handle? It was hooked to a 3-53 you say. Rollers go forward and backward. Is this a transmission with more than forward/reverse? For something you say you don't use regularly it might be opening a can of worms that is not worth fishing with.

Thats the big question. Our grandpa had a C7d with a Detroit in it in the mid to late 90's. He preferred it over the C6. We are just trying to figure out of if it would work for what we are trying to use it for. It is a 3 speed with forward and reverse. Thanks for all the reply's

On my C-7 the transmission is seperate from the detroit there's a drive shaft between them. My power shift will pull anything you hook to it but just not very fast.

i have a funk in an international s8B, they are hard to get parts for since deere aquired funk.
i think you are barking up the wrong tree with that particular trans though.........better off using a clark or allison set up for a skidder, the transfer case is alreasy in the trans and both those units are bullet proof with good parts availibility.
also the same clark and allisons are in front end loaders so you could find one that way.

[eichenberg93]

Thanks for your opinions on the idea. Just weighing all my options for what would be best way to go. Its not something that going to happen Tomorrow. More than likely if we do anything with it. It will be in that perfect time of year called "Frost Laws" ;) 

[ga jones]

Treeslayer is right an allison or clark would be a better option. Clark's
Are expensive from what I've seen. Allison is a truck transmission and available at any truck junkyard. Easy to get parts for.

We had a selet-0-matic in a ford tractor and the trans went and was to much to fix.

the allisons iv seen in loaders were not what is in trucks...........look like a clark lol.
youd be surprised, find an old straight frame michigan settin and buy it for scrap price........i bet the trans is fine most times.

Several things to consider, Along with the convertor you need a charge pump and clutch pressure regulating valve for clutch pressure, and you need a PTO to drive the winch even though you have a grapple. Clark trans would need to come out of a skidder, not a front end loader for the right ratios, PTO, and an oil cooler for the trans oil. Funk trans may have parts availability issues. Allison aren't the best in a skidder, it is basically a truck trans.

[eichenberg93]

A Allison is a good transmission. But the only problem i see is if we could find one that would bolt up to a Detroit. All the allisons that i have see in pickups are setup for a cummins. Maybe it would be a good time to do a cummins swap. :D
The transmission in it right now came out of a 1 1/2 Ton chevy truck . The rations are same as what are in a truck . The only difference is the input shaft. What would be nice is to find one that would fit in the same spot as the current transmission. Our transfer case is still in good condition. Thanks

the pto is snap to convert, remove a cover and install seal and yoke.

i did not know the ratio may be different..........you need to stick around here more, you got alot to teach us.

on the allison, get one out of industrial equipment not a truck. they are different.

[ga jones]

The Allison's I've worked with in timberjack 200 series are at545 truck transmissions they bolt right up to a sae 2 bell housing. I've only had experience with those.

[eichenberg93]

Thats good to know. How does that work with the allison in a timberjack. Do you still use the transfercase for Foward or reverse? or do you just have One reverse Speed?
