I'd like to change the Dexron III fluid and filters in my MH3060 Allison transmission. I've heard there are a few tricks to it, but is doable(I've changed all of the other fluids and filters on my coach myself). I've searched, but can't find an installation procedure for doing this. Can anyone help? BTW, I'm not interested in switching to Transynd.
If you go to this link and download the Fluid/Filter Recommendation for the 3000 Series (its at the top of the listing) on Page 8 of this publication is a drawing that shows the locations of the drain plug, filters, bolts, torque values, and the filter Assemblies.
With this you should be able to do the job. When you refill the tranny, just fill until it is on the low mark of the tranny and then run the engine until it warms up and recheck. The tech had me put the parking brake on, tranny in "D" and set the high idle to 1500 rpm's to warm the tranny fluid. Then he made sure the fluid level was only 1/3 of the way up between the "Cold" and "Hot" marks with the tranny in "N" and engine idling.
Just had ours done a couple weeks ago at Western Branch Diesel and refilled with TranSyd, it took 19 quarts but the tech removed some "port" plugs and was able to get more fluid out. The cost was appox $405.00
It took the tech almost two hours, so it is a long process.
