If you searched a few , You may have found other talks about these trucks and the simple answers you have would have been dealt with . I will give a fast answer on reverse. driver error just like rolling tham over, the Army, Allison and AM General all did studies and changed nothing because nothing is wrong, BUT with that said, The drivers were told no reverse in low, Yes the truck in low goes into 6 by. It also is as low in reverse as a D 6 Cat . Yes you can split the case by shifting into low reverse when hurrying the truck or under strain, The truck was designed to be as low as it is and stands a solid and tough drive train, tested with more mies in the past few gulf wars than any other truck. The problem almost all went away after driving training , And just not letting the mass's of drivers use low reverse, It is hardley ever needed anyway, i have used it allot, i just had to, I have been running my M 925 for over 7 years, I had one of the first out. This is a huge auto trans, that is super duty. It is 80s tech. And it is good, Don't try to compare to modern trans's and trucks, its an antique now . One very simple rule, This is a tactical vehicle, Not a race truck, Those whom want race trucks are foolish to try to make Mil trucks that way as far as I see it. Never rush the shift from one direction to another , You will never have a problem, With the R's up if you rush that trans, When she finishes shifting she will slam that case, Its a side shift trans. It is what it is. Most should follow the rules . Never use low R . But You sure can . And it sure is done and has been done. Hows that for a short answer
Beautiful truck all the best :
Oh I would love to and hope to eliminate 6 by in low. For us it makes sense, here allot of guys think what they think is what the Mil should do. Actually they have a different set of ideas in more conditions/climates than we ever will, But for us the 6 by low auto is better not there,
