Long story short, 2000 GM TopKick 6500.....retrofitted a 5.9/AT545 out of a 95 F700 ford truck.

I had an MT643 behind it for a while, it's much better (lockup) than the 545 (non lockup) but no emergency brake so I swapped it for the 545. This is a work truck, needs an emergency brake.

Anyhow i would like to swap for the Allison 2000 for a few reasons....overdrive, lockup and emergency brake drum.

Can anyone give me FACTS on what I will need electronics-wise? I'd like to plan it and have everything ready. Again truck is for work, hauls aggregate and does snow in the winter. Don't need any fancy stuff, just whatever I need to have it work well.

Thanks in advance
