Can someone help me ID the Transmission that is in my CJ7 ? I know the motor is not orginal to the jeep since is has a 360 under the hood, I pulled the numbers off the metal tag and tried to do an internet search and came up with a 3 speed auto but the transmission is a 4 speed standard these are the numbers off the tag

Upon further cleaning of gunk off the transmission and further research online I have come to the conclusion that the transmission is in fact a T4
Ahh, I missed where it was swapped from an auto to a manual. Just to add a link again, our extensive Wiki and VIN decoder may help you later...

That’s not a very good combo. Lots of power.

So using your vin search tool, according to my vin the Transmission should of been a T-18 but it also has a B for the motor and your tool dosent list a B in the options

Jeep was notorious for using crazy VINs with non listed letter codes.
I was able to find that "B" was for the 4 cylinder GM 151 . I'll add it tonight to the decoder. Thanks for the heads up.

Is your engine factory? If so I'll ad B to the tool. Dealers could order a 360 from the factory so the VIN would show the correct letter and then the dealer would install the engine. See (Link)-> Engines -<
Honestly Im not sure, I was reading the tech manual you guys have here and according to the code on the valve cover of the motor its a 302 not a 360 like I was told when i bought the jeep I think I need to do some more research and in answer to your question I was told that the motor is not factory and was swapped in 2 owners ago, honestly theres no telling lol it could be a 360 motor with 302 valve covers is there any casting numbers that i could check to actually see what motor I have?

:banana:At least it's a V8...

Can you post your complete VIN excluding the serial number? It would help me check things with my decoder.
 
B has been added to the decoder. Don't know how I missed that one... Code example.
