So for those that are trying to determine what 8HP70 transmission they're buying there is a partial VIN stamped on the forward part of the Bell Housing. I have enclosed a picture of mine.
You will be able to determine the exact year from the partial VIN.
I was able to determine the complete VIN from this number and verify that the trans I bought is from a 2020 Charger 5.7 R with 20,400 miles.
Also this 2020 trans has all the pins in the TCU plug.

Domi works has a kind of decoder to each differences between the 70,90 and others like 45etc etc pretty helpful
I'm thinking about doing this swap, I have a transmission on the way. I'm thinking about using the maxxecu race since I have to run a different ecu anyway. The maxxecu can only run the gen 1 8hp70 and 8hp90 . In 2019 dodge switched over to gen 2 8hp75 and 95.
This made looking for a transmission a little confusing. However newer ram trucks (classic) kept the gen 1 transmission.
I'm swapping this behind my 434 ls3 based Chevelle from a t56 magnum f.

Keep us posted. I'm curious to see how your experience with MaxxECU goes.
Got my transmission in, need to research on what adapter to use. I see most people use the domiworks adapter. But I see seems legit garage sells a different one that made by adamat that comes with a flywheel. Had anyone here used that one?

Since you're using the truck transmission, look at the LOJ Conversations adapter.

I cannot stress enough. Do not work with seems legit... They'll leave you high and dry on certain things. Go with anyone else.

I'm probably going with the loj kit that was recommended above. I'm still debating on the maxxecu vs turbolamik. I'm running a gto e40 which I think cab send the data over can as well but I want to go get rid of it when I rewire my car.

I can say I have no experience with maxxecu but turbolamik works extremely well!
I have an 8hp90 with a 10 pin connector. What is the solution to making the tcu work? I have seen where the 90's have a couple differences to the 70's and others. Are those sensors or pieces swapable? or do I need to find a tcu from a 90 with the correct number of pins of on the connector? Is this an issue anyone else has ran into with the 90's? Thanks Forgot to add Im using a Turbolamik
This was a low mileage 8HP70 from a RWD Dodge car. It is already modified for use with the TurboLamik TCU.
I swapped in a new oil pan which also has the filter assembly built in.
I am waiting on Amazon to deliver a new 5th Gen Camaro starter, which is what the Cougar has already. I will mock it up with the DomiWorks adapter do see where the transmission bellhousing needs to be notched to clear the starter nose.
I stated earlier that I was using the 5th gen Camaro starter. Well, that starter has a unique nose on it and it does not work well with the Domiworks adapter. I recall having a similar clearance issue when I used that starter with a stock T56 bellhousing. Instead of butchering the adapter (more than I already did) I ordered this truck starter. It has a different nose, but still have the connector for the solenoid wire.
You can see where I have already clearanced the adapter, but had I used this starter from the beginning, that would not have been necessary.
The other difference with this starter is that it does not have provisions for the heat shield, like the one that is used on the 5th gen Camaro starter. I don't think this will present any issues.
This shows how much the bellhousing has to be notched in order to clear the nose of the starter. I could have done a slightly smaller notch, but I didn't want to keep messing with it.
I plan to 3D scan that area and have a small cover designed and 3D printed. The engine swap party is a little over 2 weeks away.
Sure the LS1 starter has a very small snout (Holden or Pontiac gto) GM 92169668, iirc that is what adapter is based around.
The starter that is pictured is a 2013 truck starter and it would fit without having to modify the adapter.
It isn't the size of the snout but the position of the snout relative to the plane that meets the block. The 5 Gen Camaro starter has less room in that dimension despite having a smaller about.
Looking at the Holden/GTO snout, it actually looks like the 5 Gen Camaro starter snout, and I bet it won't fit either.

I only use PMC kit, and it fits those that are also based on the LS1 that was available Euro side. I’ll see if I can get some pics next one I dummy build. But is there any difference between the spacing on the Gen3/Gen4 blocks do you know Andrew?
