This was a custom printed mechanical linkage design to take Cummins throttle movement and transmit this to a PWM tps for the Allison.  It was later replaced by a black box I designed using an esp 32 to tie directly into the Cummins tps signal wire and convert it to a PWM for the Allison

Build story

Started off as a USMC M1165a1 with the 6.5td and 4l80e transmission.
Currently in process of swapping in cummins 24v mated to the 4l80. Plans for the 6spd Allison 1000 later down the line.

The 4l80 has finally been swapped out to the Allison 1000 and an unexpected turn, I got a 6.7 too cheap to argue with. So the 24v came out and the 6.7 went in.

Now to get some ac finalized

The plan is to eventually turn this into something like a custom H1
