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, leaving wetness around the transmission and dripping on the garage floor. Be forewarned, it may be easier just to 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 details. NOTE: The special tool shown in the video can be purchased separately below if you plan on removing your Bowden cable from the transmission.
