I am trying to complete some research regarding comparison between the Allison 2500PTS trans and the 3000PTS. I understand that the 2500 is a standard option, but is there truely an advantage to spending the extra money for the 3000?
Has anyone had experience with both transmissions? Is the difference noticeable?
Also does anyone have insight on the price difference between these two?
While both are six speed transmissions, these are completely different transmissions built in different cases with different internal parts built to handle different torque and horsepower ranges. The 2500 will handle the torque rating of 660lb on a Cummins ISB but will not be adequate for the 860lb torque rating of a Cummins ISC. My general rule of thumb is 280hp and less on the ISB, the 2500 will be adequate. A 300HP ISB and all HP ranges on the ISC gets the 3000.
Here is the real difference I have experienced: If you plan to keep the bus for 12-20 years, and you select the 2500 series, then be sure you have an adequate transmission jack to replace it a time or two.
3000 is a tough SOB and my first choice seeing how I cannot accept less than 15 years of good, reliable service.
