I have a 1976 CJ-5 with an AMC 360 hooked to this unknown transmission and Dana 300 to a ford 9" rearend.. I'm running 36" TSL Boggers and have 6 inches of lift.. I pulled the tranny due to it popping out of 2nd and grinding going into third,, it is a 3 speed manual trans.. I'm hoping someone will help me identify what type is it,, the only numbers on it are C-CU-OU and the numbers 2603347.... HELPPPPPPP... thanks..
