Having a problem with my allison md 3060 transmission
Hi mate I had the same problem with a camper once and the only way that you will ever stop it from shifting hard into gears down shifting or up is to take it into a Detroit Allison work shop and ask them to reset the throttle position and reset Un-adaptive shifts then to do an Fast-adaptive shift with the electronic tool called Allison Doc.
Ask them also to do a clutch report on the electronic tool, that will tell you straight away the condition of the box on the inside.
Thats the problem with these new electronic transmissions they force you to go back to the suppliers. If I had my book here I could have helped you with the fault code but you would have had to take it in any way to get all the parameters reset.
What happens is that when you buy this trans new they set it to UN-adaptive shifts then to fast adaptive then it learns how long the solinoids should be open and how quick to open them to have a good shift, but over a few ignition cycles the fast-adaptive changes to normal over a year or two the clutch plates wears with a few 001 and the computer cant keep up have to be reseted which is normal to them, expect to take it back every year or two to be reseted.
