New to Auto Transmissions

I have always had a manual on all of my 2nd gen cummins trucks, mainly due to the obvious reason's we all know with dodge transmissions, to include failure, reliability, strength, and PRICE (auto), especially when you add any power to it.

So now I am trying to do a crash course on auto transmission in 2nd gens cause I am clueless on everything/anything with them. Man this is making me feel so dumb... withstupid

Gonna be trying to learn about lockup, torque converter stall, billet this and billet that, what auto parts, auto computers or tuners?, etc...

I am so so so tempted to put a nv4500 in this build, just for the availability and strength! Please reference 24v 1500 Cummins Thread check it out in the cummins swap section)

But I think Ill regret it in the end since this will be a play truck obviously. (Keep in mind I plan to try and keep power around or below 600hp) Ill just be spinning the tires irregardless in this light truck... NO - 4wd

I have rebuilt my NV5600 before (for my truck in sig) but I think rebuilding an auto would be way out of my league even with my extensive mechanic background with JD.

So Ill list just a few questions/thoughts to start with for the well versed auto guys.

1- Should I still go for an auto over a simple nv4500?

2- Could I rebuild an auto? (this could expand into another big discussion via what parts/brand etc.)

3- Who/where would you choose to send a core to and have them rebuild it for you? $$Suncoast - ATS$ Transmission - ETC

    Think about your purpose mostly. What is the plan for the truck and what will it be used for the most? Then build this truck for that purpose and enjoy the craft you made! I totally understand why so

    Never actually. Never had 5th gear nut issue. I broke mainshafts twice and destroyed 5th gear and 3rd gear. Never 5th gear nut.

PCM that has the proper software for automatic Cummins. Basically you need the entire under hood wiring harness. This should have the transmission connectors. Make sure the ECM is ready for that PCM so it might be worth sending the two off to Auto Computer Specialist and let them flash them both. I've done one auto to manual swap which was easy.

Personal Note. Sorry for being MIA I've been working hard here in the yard trying to get everything clean up after the landslide.
