Driver error, Just like the >> Army, Allison and AM General came up with the exact same reason for early failures ... after all the re testing after a rash of cracked cases started showing up many years ago. The facts I have read show after more extensive driver training the problem was severely reduced. And no changes were made because they were and are fine . Now you cant completely fix stupid. These are TACTICAL vehicles and can not be driven like a street truck ... the tire traction alone is enough to put severe strain on the drive train. And no matter how many times a Soldier says " No really I waited for it to shift applied the accelerator slow and steady just like we were taught and the thing just blew up .And No I was not over loaded !!! . LOL) really ? That's like " These tires got me stuck LOL)))) breaking brakes free by ramming it in reverse an forward ..really Sorry that says it all.
Now I see people saying , In theater we had problems. " I need facts .... Well lets say>> with facts these trucks have more than proven them selves . the NJ unit here in conjunction with a PA unit put more miles on these yes they had mostly 939 series More miles than the Red Ball express, I was at one of the ceremony's when the citations were being handed out here in the first gulf war. there were a very mix of drivers in these units, I new or know most from The unit here, They ranged from Vietnam Vets that were drivers then and new guys . ALL the older guys I talked with over the years following said the 939 series outperformed ALL the previous M series trucks they drove. Just an eye witness account from me )))
I just think the facts presented by Me should be taken into consideration, these trucks are NOT fragile. In ALL climates an ALL terrains they have more than proven them selves. But like I said You cany fix stupid.
ALERT DISCLAIMER ALERT >>> I have more than fulfilled my quota's of STUPID LOL))))))))))))))))))))))))) So I speak from experience )))
Drivers that tend to shift from forward to reverse before the transmission finishes shifting will cause this problem , that's driver error period. These trucks can back up fine all day long in low. UNLESS # 1 you do not let the transmission finish shifting before changing direction . #2 do accelerate knowing its in 6 by and just disregarding the fact of just how tough these trucks are, And when the center of the driver s foot and traction explode its >>> Driver error . That is the largest problem and once again proved beyond a shadow of a dought here in this thread.
A very simple fact, This trans is late 1970s early 80s technology. It is exactly what the Army asked for, It is geared as low in reverse as a D 6 Cat . You MUST let this trans finish shifting before you change direction.
