Jeep ZJ 1993-1998 slipping/clunky transmission (and others)

Short article - I thought my clutch was going. Topped up the transmission fluid ( read the manual for the correct type, read around for current replacement - old fluid no longer exists but you will easily find a compatible one ). It's a little fiddly because you have to add it in the dipstick tube which is at an an angle and a little awkward to get at, use a funnel and a tube/syringe. Result - no slipping on cold start, or clunky gear changes. Too easy!
