    Transmission control was part of the PCM in all Dakotas and Rams.

    Thinking of kicking the 5spd to the curb.. And replace the drive train with a 6.4 and a 8hp70.. Been trying to research the wiring logistics of it.. But finding info on it hard to find.. Previous owner Don removed original engine for the 408 so it's no longer original anyways.. Rear axle gears were swapped to 4.56..

    Totally up to you, but I personally like rowing gears - it's the one thing I've always hated about the R/T package. I'm dropping in a new motor and doing a T-56 swap in mine. As far as a Hemi swap, I thought Holley had a kit or something, that included wiring that mated to factory harnesses?

    Mopar makes 392 create kits, with the ECU, wiring, gas peddle. This is set up for a manual transmission. To use the 8hp70 you need an external controller. Sound German engineering makes the controller and harness for the 8hp70.

    You can also use the Terminator from Holley and they make a harness. It can control the 46RE, and you can get the harness for that. You need to figure out the kickdown, there are some options out there. To control the 8hp70, you need to go back to Sound German.

    Holley makes motor mounts, headers, transmission cross members and other parts for swapping a hemi into Dakota.

    Mopar also announced they'd be doing standalone stuff for the 8HPxx transmissions via Direct Connection back in August when they unveiled the new EV Charger, body in white program, carbon fiber bodies, etc. They've still yet to say when they're actually going to follow through with the transmission stuff, though...

    Direct Connection TorqueFlite 8HP70 eight-speed transmission — the same transmission used for 392 HEMI®-engine-fueled Scat Pack models — available for plug-and-play use with Direct Connection crate engines

    Missed that. Pondering whether they will offer a kit to use from pulled transmissions your if you need the buy the entire transmission for a plug and play solution.

    Allegedly it'll be standalone capable and eventually sell stuff for the 8HP90 as well, including crate transmissions for both flavors. Allegedly...
