Re: YJ Transmission Problem
Back to my transmission... I assume that I have the AX5 in my 2.5 95
YJ, are these worth rebuilding or should I consider replacing? If so,
with what - something beefier? I've been doing some homework here
http://www.jeeptech.com/trans/ and need help sorting thru the options.
Thanks,

Re: YJ Transmission Problem
It sounded like you were describing a broken overdrive gear. I
believe rebuilding it is your only option, as the input and output
shafts are different than the AX-15:
