Time for an update. I haven't been on this website for a few months, but the Durango is doing fine. As with any swap, there is never an end to all the little details. But it's getting there. Another video.

This post is 10 months old I think since the last answer. I hope someone sees this and has an answer. I have a 2000 Dakota my dad left me when he died. It has the 4.7 in it and it is very tired. Its been overheated and I don't want the 4.7 anymore. I do have a complete Chevy 4.8 in the garage and this post has me thinking. Can I possibly use the transmission that is currently in it?
Can I wire the 4.8 to work with the Dakota's underhood wiring? I'm a bodyman, not a mechanic. Am I biting off more than I can chew? Thanks for responses. I don't want to buy a transmission and stuff. I would like to buy a transmission adapter plate and use what I already have,

Hey there,

Sorry for your loss.

Unfortunately the Dodge trans and wiring will not work with the 4.8

the trans can be adapted with enough time and money as you can get a adapter plate made, but it wont be cheap.

the wiring is a completely different story.
the 4.8 and the 4.7 wiring and crank/cam trigger signals are completely incompatible. Even if you do get everything wired up the dodge/mopar ECU wont know what to do as the trigger signals are completely different between the 2 engines.

the best bet if you want to use the 4.8 would be to get a stand alone ECU or a GM PCM that has been converted for use in standalone applications.

once you go standalone/GM PCM I would just use a GM trans.since its a better trans and the PCM has control over it.

In your situation i would just get a junkyard 4.7 or a rebuilt 4.7 as the 4.8 swap is definitely NOT easy, and a lot of custom parts have to be made to get everything to work together.

Ok, I'll get a complete wrecked Tahoe or something else that works for the swap and go GM all the way. Thanks for your input.

I have the engine in and mounted. The pan doesn’t clear the front differential tube. The bottom of the oil pan is 7 inches long. There had to be another oil pan that is 1.5-2 inches shorter in length.what oil pan are you guys using? This engine came out of a 2007 Chevy van.

I used the GM Hotrod oil pan on my 1998 swap. The steering setup is different, but it may work for yours as well. Here's a page that shows the various LS style oil pan dimensions:

That site is very valuable for what you're doing.
