Aiiison 300MH trany service

[Coach_Cleats]

Our 2004 Cheetah has 73K on it and I have owned it since 2007. Is it time to change the Transynd fluid and filters? Not having any problems to date. Any ideas of what this service might cost?

My trash collector recycle people will take motor oil it has to be in a clear container with screw on lid marked motor oil they will take 2 gallons at a time. The other day I left 2 gallons marked trans oil and they did not take it so I left it there (end of driveway) next week they took it. So now I am not sure if they take trans oil or not????

I cut. a 55 gal barrel off at the first ring up, and get a buddy to help empty.

But here 's the kicker,, who recycles tranny fluid? Autostores that collect engine oil won't take it.

Oil drain pan

I just use the same old Rubbermade bucket I use for oil changes. Line with black HD trash bags for easy clean up. Use an old coffee can and funnel to transfer oil fluid to pail when finished. With a pail you have one quart left over-- I usually just ask the service department at the Allison dealer for an empty Transynd gallon jug and pour off the quart before I put the new fluid in the transmission.

All the mechanic work I have done over the years I wish I had bought this pan years ago. I like the expanded metal grate it has makes it easy to drain oil filters and I can't drop the oil plug in the bottom of the pan. The wheels keep me from sloshing the oil out when getting the pan out from under the vehicle. Now I just have to remember not to run over it.

And the money you save by doing it yourself will pay for the drain pan...:)...Dennis

A 2004 was close but I think should have transynd. No matter I would run a fluid Analysis and I’ll bet if it is it’s still in great shape. Transynd has a large use life, esp in light use like a motorhome . I’d still definitely change it , but for a few bucks you can run a analysis on it and get a report and know what your dumping and if you have any issues to be aware of

What fluid is in the transmission from the factory?

Mine had a sticker that said Transynd you need to know because when you drain it you don't get it all out and you are not supposed to mix fluid types. Look around your engine bay and see if it tells you. You may also be able to find out through a dealer for your chassis with your VIN number. Mine had the sticker in the access panel where you would add the fluid.

Also I think for me personally the torque value for the filter bolts are to much.

I agree. I was uncomfortable going to full recommended torque. Ended up about 10% below the minimum recommended torque. Never a leak on three different coaches/transmissions.

I don't see how you can change the transmission filters and install 19 quarts of TranSynd especially when the fluid is roughly 70 bucks a gallon

I paid no where's near that per gallon.

Next time I do mine I will not use a torque wrench I will just snug up and go by feel.
I dodged a bullet when this one snapped and I was able to remove.

I paid $39.95 a gallon for Transynd from the local Allison shop and I think $57 for the filter kit. Napa wanted over $129 for the filters and they did not have Transynd. It might have been $279 total I will look up the receipt.

You must be buying RV dealer Transynd @$70...good truck shop/Allison usually $35-$45.

Shop around some... 🙂
