hi i have jeep liberty kj 3.7 2006 sport with 60km do i have to change the transmission oil the manual says 100.000km the oil is in 17 years old

What I did with my used Liberty, is I used my miti vac fluid vacuum to suck out about 3 quarts ever oil change and gradually renewed the fluid. After the fluid looked and smelled better, I dropped the transmission pan and replaced the filter.

That way there was no shock to the system.
