Allison 4 speed to 5 Speed swap

I have a coach with the Isuzu 6 Cly diesel and the Allison 545 4 speed and I would like to swap in a ally 5 speed. Anybody with exp in this kind of swap that can share info on what I need to make the change.

I have a line on a 2004 Topkick with a 2000 series Allison 5 speed and TCM .

Any help would be appreciated

Even if you can hook up the trans will the electronics needed to control the trans work with the engine/trans combo?
Will the torque converter be the right one for that engine? On the 3000 there are 6 or more torque converters to choose from to tune it to the engine output.
Are the gear splits compatible with the the engine output?

The trans I looked at is a 2000 series not the 3000. Apparently all I will need is the wiring harness and a throttle position sensor and it should work.

Shepherd57 see the above posting on the Allison 542/1000 swap. You will need to make that the torque convertor stall speed is correct for you engine and the TCM must be matched to the engine also for the correct shift rpm points. This not hard to do as it is only a software change.
