These transmissions are now 40+ years old, and with age comes hardened o-rings and seals, leading to what I call "pesky" leaks. They are not bad enough to flow on the ground, but they do leave wetness around the transmission and drips on the garage floor. In this 27-minute instructional video, Kent will walk you through the steps of fixing these leaks. Be forwarned it may be easiler to just remove the transmission to fix these on the bench. A couple can be readily fixed with the transmission in the car. Others require dropping the transmission down, and in the case of the bowden cable it is an advanced DIY job to try to change the o-ring with the transmission dropped down. Watch the YouTube video below for more detail.
