Wow! The cool factor just went up another 10 points on this truck. I wasn't aware of the mix/match on the drive train using GM and Ford components plus the over drive gear splitter.And a Cummins/Dodge engine. A trifecta of automotive companies. This truck is off the charts cool and built the way one should be and the main computer controller is sitting behind the steering wheel. Kudos again on the truck build. Not your average diesel swap.

It's definitely always felt as if you could easily squeeze a whole nother gear in between lol. Even 4-5 has quite a gap.

@redeyecafegarage7484 Жыл бұрын

If the computer is hooked up there’s a speed sensor that needs to see at least 35mph before it will engage. The hydraulic pump is driven off the driveshaft speed so you don’t want to try to shift below 35mph. If you override that and try to shift going slow it will slip.

That's not true. I have been using mine for about 13 years on my 1990 D250 with a Cummins and a Getrag 360 and exhaust brake, and it works beautiful.
