Need Information. What trans?

That's an A518 also known as a 46rh or 46re depending on what year. 46rh was hydraulically controlled unit and 46re was electronically controlled. They were used in Dodge Rams and Dakotas behind V8's and in Jeep V8's but not sure on the years there. The only thing odd I notice is the strange half moon cutout in the lower part of the bellhousing. I've never seen a Jeep model so maybe this is one.

The numbers I said to look for are not raised up like the ones your seeing. Their stamped into the housing and their small. Only about a quarter inch high. Look right below where the shift linkage slides onto the shift shaft at the rail above the pan and you'll see a long number there. That's it. I originally said there was 2 sets of numbers. I may have been wrong. I'm used to working on 85 and older transmissions which had 2 groups of numbers. Mr.Mopartech says one number that is 17 numbers long. Now that I think of it I think I heard that somewhere else so I think he's right. Anyhow that's where the number is.

BTW: What do you plan on putting this trans. in? The reason I ask is if it is an A-body car your gonna have trouble getting it in there. The OD unit is so fat it won't clear the floor pan and crossmember without alot of modification. It'll work in the larger cars but not in a Duster/Dart/Demon/pre70Cuda Etc. without mods. Also it is a lockup type trans. that will require an electrical circuit for the torque converter to opperate correctly but it's not really hard to build if your electrically inclined. Just another thing to think of.

If you think you can use this trans. you definetly need to verify the year because if it is newer than 95 it's a 46RE which means it's electronically controlled by the computer and will be very difficult to make work. In other words you need a computer to control it.
