Hello,
I got a 98 dodge 2500 automatic with an Allison’s transmission in it. The person I got it from I don’t think took great care of it. Truck runs well,no codes or anything but when driving there is a shift delay. It seems to shift first and second well then a delay to third/4th.
does anyone know what that could be?

 

I highly doubt there’s an Allison transmission in there…

to me sounds like either it’s in need of fluid/filter change, or tv cable adjustment

 

Definitely need some more information on what you have going on here. pictures, or model of the Allison?

 

Yeah.....if there's an Ally in there you've got a standalone controller and everything is aftermarket and was done by a previous owner

 

If it is an Allison and a 4spd there would be no controller, they were fully hydraulic, and about every school bus built in the 90s and early 20s had an International DT444/DT466 or 5.9 Cummins backed by an Allison AT or MT series trans, so the possibility someone swapped one into a Dodge is quite possible, however a major downgrade

 

I felt the same way after I bought it, I don’t know everything but I believe I know trucks (dodge trucks) well. Thanks for the information and I’ll get more information give you all a better descriptions.

 

You could put in an Allison but it wasn't from the factory.
