8hp70 tcm?

[Ram1683]

With AlfaOBD and then connecting to the gearbox and setting the VIN through

Which obd reader do you use?

You'll still need to pull the valve body out to get the TCM fully removed from the trans, but it's really not that difficult. It took me longer to refill the trans than it did pulling down the valve body and getting the TCM

I use the OBDLink MX+. I hear people going cheaper and they are always having issues with connecting or having changes save. I never hear of people having issues with the MX+

Wait... ya lost me. I still need to swap in my original tcm and program it? I've had mine out twice now doing the zip kit, not bad at all but There's always that sense of nervousness when dealing with valve body bolts.

I might be backwards on how this is going. If the TCM is being transplanted into the trans already in the truck, you 100% need to program the VIN. If the TCM already programed to your truck is just going in the body of another transmission? Then you 100% don't need to reprogram it. Should be plug and play.

That's impression I was under. Original tcm doesn't know if the mechanical parts have been changed just as long as it knows the ecm. If I leave the tcm in my new unit and programming it is as easy as using the alfa app I'll just do that.

Exactly. It's a time saver to drink a few cold ones in triumph!

I've been having lunch with mine. Frosty adult beverages will be for when I get it in. Definitely gonna buy the app and cross my fingers

You can't go wrong with AlfaOBD and the OBDLink MX+ combo. Hands down the most versatile tool to keep in your tool kit for these Rams. Really any FCA/Mopar/Chrysler/Stallantis vehicle. I'll have a few cold ones in your honor and wish you the easiest of installs. Look forward to seeing how it goes so keep us posted!

Nope. I legit just swapped em, set the VIN and was off to the races. Two months later and it still works like it was never swapped in the first place.

Excellent! Thank you!

For clarification, in Alpha, you went into (Ram 1500 > Transmission > Chrysler ZF8HP45> car with open hood icon > VIN Write) to do the VIN write?

It's crazy that these Mopar parts are extremely hard to get. The reman valve bodies are all on back order across the country. The new valve bodies are in short supply, and cost 2k+. I can't justify spending over 2k, just for a TCM. Especially since my valve body is fine.

I found a used trans for $450, and it comes with a 6 month warranty.
