Ya have to realize, out of the millions of Dmax produced, they are highly reliable....and they just don't break down....much.
As a result of that ^ AND it being a Diesel, there just isn't much experience out there with shops....again, they don't break down. It's hard to find an experienced repair person who has tackled a similar problem in the past.
So with the DF archives we have, compiling real world experiences from a User standpoint, many times your solution found here is right on.
But trying to find a shop to act on this info.....scarce.
Just hope you never have a problem with the Allison. It's probably the most reliable item on the HD.
Trans shops, they don't work on transmissions anymore like in the past. They just pull and install off the shelf remans....that come with a 3rd party warranty, which also covers their labor if something goes wrong.
No liability on their part, they're covered regardless.
Try and source an Allison certified repair shop on their site, good luck with those. They're all shops handling large MD and HD trucks, where they just roll up under 'em.
They don't have any lifts in the shops, never use 'em.
So they can't work on your small, low to the ground HD.
