I recently bought a 2014 ram 1500 that needs a transmission. The truck still runs and drives, just not well. I’ve been looking at different options for transmissions, and was looking at rebuild parts for mine, but a lot of the times websites want to know if I have the 845RE or the 8HP70. The truck is a 2014 5.7 Hemi with the 8 speed transmission, 3.21 axle ratio. I’ve managed to find all that but I don’t know how to tell which of those other 2 options I have. Any help?

I forgot to include that the truck is 4x4, but it does appear to be the 8HP70, going by that website GTyankee mentioned, which is also what HuskerRam said. That helps a lot.

Hemi 5.7...65RFE...4.56
The 5.7 Hemi 2014 Ram 1500 could have either the 65RFE or the 8HP70.
If the shifter is on the steering column its the 6-speed.......if shifter is a dial on the dash its a 8-speed.
If it really is a 3.21 gear it's probably the 8.........most of the 6 trans came with 3.55
It's very easy to tell by the shifter location though unless they did the 8HP70 swap which is quite expensive.

The shifter is on the dash, it was the rotary/dial shifter. And I crawled under the truck and it has a 3.21 sticker on it so that’s how I found that part out.
