Toyo310 Report post Posted February 13, 2019 I have read on different forums that the Allison MH2500 transmission is a very light duty transmission. And, that on most coaches it is at or over it's load limit. However, I have never read anything about the failure of one of these transmissions. If you had a failure or know of one please let us know what failed and the reason for failure. Share this post Link to post Share on other sites
jleamont Report post Posted February 13, 2019 Toyo310, Here is the cause of failures that I have experienced. Solenoids fail or lighten up on application pressures which cause slippage and burn up clutches. In My experience this has always happened around 80-100,000 miles. They are notorious for internal wiring chaffing against the pan, external wiring issues and Transmission Control Module failures are also fairly common. On a good note you can purchase a remanufactured 2500 for $2300.00 which in the transmission world is pretty inexpensive. Share this post Link to post Share on other sites
wayne77590 Report post Posted February 13, 2019 We ran our 2008 DP with the 2500 for 9 years and never had a problem. We let Freightliner keep up with the maintenance that we scheduled yearly. Share this post Link to post Share on other sites
manholt Report post Posted February 13, 2019 I never had any problems with my 2500 in a 2007 Silverado, 4 x 4, caring 107 gal of diesel. Sold it at 57,600+/- miles! One of my close friends, bought the same truck, with the same set up. Still got it, over 200,000 miles now and no problem with the 2500...he also hauls a 4 horse trailer!
