I bought the wrong damn one!!! Needed one for the 3.0 R150 not the 3.4 R150 fack me! This is brand new sealed, never opened!
So, this adapter is to mount the gear driven RF1A transfer case to a 3.4 R150 5 speed. Pretty sure it will not fit an auto as Marlin was specific between auto and manual when i bought it. You can check all the details on Marlin's website link provided
