- 1979 CJ-7, AMC 308 V8, GMC hydra-matic trans, unidentified t-case as of now (think its stock) stock dana 30 front and AMC 20 rear.
Hey guys, i just picked up a 79 CJ7 . Second cj iv owned but man is this one strange. She has the amc v8 in her with a nice edelbrock kit on it, runs smooth and strong tied to an automatic Transmission . Its really clear that someone swapped out the manual that used to be in it and replaced it with this auto. It says its a GMC hydr-matic and Im not at all familiar with it. Its tied to a Transfer Case that I cant identify. Both the Transfer Case and Transmission look to be mounted cleanly to stock mounts.
The 4wd setup in this rig is that fulltime 4wd set up with a high-low lever mounted just below drivers right leg and a glove box locker dial.
As of right now the truck runs and goes... But only forward, reverse wont work, she barely crawls in reverse and it stinks of Transmission fluid if you rev it up in reverse. Obviously gonna need some Transmission work, which sadly iv never worked on an auto Transmission in my life. What am I in for down there? Is it even worth working on or should I just replace it?
Any help or guidance greatly appreciated!
I should add that i suspect the Transfer Case is a Dana 20 , its what should be in it after all, but I cant tell if its a 20 or 300. Not sure of the difference.

If you have any mechanical skills, you can rebuild the
