our garbage trucks have the 5.9 with the allison tranny. i have been driving the same one for 10 years with the VE-pump and we work the crap out of those motors. stop/ go plus hitting the engine speed up to pack the trash every other stop. never had a problem with this motor in 10 yeas. cummins= amazing!!!!! truck weight is 23,000 empty my max load was 41,000 and that motor takes it!!!!

 

does the allisons hold up in the garbage trucks?

 

Or church bus has a cummins with a allison tranny behind it and we turn the cummins up cause its a 12valve and the tranny is ether geared so low or it has a govenor but it will only do 65 so i dont know if that transmission wouldnt be the same on your truck.

 

the allison has had no problem at all! heck i think they service them about once every 5 years. not good! but our trucks are so low geared that they will only go 50 on the highway (empty) doing about 2600 rpm.

 

so they must be good trannys>
