Thread for general information as I had the thought to find one for my rig.

Overdrive unit available (for hiway OD only-which is what I want) bolts on back of the existing TC, requires a new rear only drive shaft, and turns the 727 3-speed into a 6-speed.

The bolt on unit electronically shifts in manual or auto shift mode with 1/2 gear increments, to the full gear shift of the auto trans.

So your 3-speed will shift like this
1 to 1-1/2 to 2 to 2-1/2 to 3 to 3-1/2

This is the site for Dodge 727 3-speed info
Dodge 3-Speed Auto - Gearvendors

Go here for more info-

Looks like the bolt on unit is right at $3200, then need shorter rear drive shaft, as unit is about 12" thick.

Best part about it, they have an exchange program so when you change vehicles, you get credit for exchange to different unit.

Units handle up to 1200 hp, then need hydraulic modification up to 2000 hp.

Looks promising....just need to find those money tree seeds and get that sucker growing

Honestly....would rather spend this kind of money for an O/D unit, rather than FI.
