Hey guys. I just got my jeep back yesterday after some open heart surgery to the tune of a new clutch, transmission rebuild, and rear end rebuild. I told the shop (unfortunately after the fact) about the incorrect information in the manual about what fluid to run in the transmission and he said they put what the book called for, GL5. Prior to the rebuild, it was very hard to shift into the gears with the recommended fluid so I was told to use ATF. After the fluid change, it shifted as smooth as could be. The transmission did need all of the synchronizers replaced but with the GL5 in it, it's shifting extremely hard again. What are the symptoms or results of incorrectly running the GL5 fluid? Does it fit the hard shifting symptoms I'm having? I knew the ATF was just a band aid and now that the tranny is rebuilt, I don't want to go that dramatic of a fluid. Any recommendations to ease getting into the gears? Is it normal to have some stiffness after a rebuild that will decrease as it breaks in? Thanks for the help.
