Allison HTB741 fluid change
I didn't know the torque spec buts its a large bolt so I just cranked it down nice and tight. Confirm how much fluid your tranny requires then you start refilling your tranny with the engine off and when it reachs a point that you can't get it to take any more tranny fluid, then start the engine and you will now be able to get the remainder in. I thinks it's because you have to check your tranny fluid level with the engine running so the level you see on the dipstick is with the tranny pumping fluid thru itself and if you shut off the engine it would all drain back to the pan and the level would go up. When you are near full and trying to add more with the engine off the fluid level is up because the engine is off and when you try to get more in, apparently the bottom of the dipstick
tube is emmersed in fluid so what you put in just fills up the dipstick tube and won't go in.
Ihope this helps!

It's easier to do than a car, allisons have a good sized drain plug and there is alot of room under there to work. just slide a big plastic tote under there and pull the plug. When refilling with fluid you will reach a point where you have to start the engine to get the rest of thefluid in. There is an internal filter and a magnet inside the pan that would reguire dropping the pan if you want to change that filter and clean the magnet.
