Can anyone tell me the best and easiest way to determine what Alison tranny I have?

Freightliner XC chassis with 300 Cummins, 5 speed Alison tranny ( D, N, R, & up/dn arrows) on control panel. 2005. Manual does tell which of the 2000, 2100, or 2500 I have. Any idea where the serial number is? Alison website would then give me details.

Thanks.

With the push-button shifter you have a 3000 series. It is a full fly by wire system.

2000 series have a T bar type shifter with a mechanical pull cable down to a lever on the lower left side of the transmission.

ID plate is on the right side of the transmission.

When you find the serial number, call Allison.

Try looking inside the bedroom closet for the several build sheets; especially the one with the large FREIGHTLINER logo on it. It tells which tranny is in the drivetrain.

A brochure for that model says it's a Allison MH-2000 - 5 Speed.
