moritz55 Posted October 14, 2009 Share #1 Posted October 14, 2009 (edited) Hi everyone .. I have a small leak that causes a nusance drip at my Speedo cable housing attached to my transmission. So before it gets worse and I store the car for winter - I'm planning to replace both the small internal and larger outer O-Rings. I ordered them from MSA. I have an 82-83 280zx 5sp manual transmission with my '73 speedo cable. Both O-Rings are commom from '70 thru '86 for manual transmissions, so I assume no serious issue with seating the O-rings properly. I have read thru this link and understand what to look for in the O-ring replacement of the pinion: http://www.classiczcars.com/forums/showthread.php?t=31338&highlight=Speedometer+Cable+Leak==> I'm searching for any helpful tips on how to change the transmission oil as I'll be jacking the car up in my garage. I'll get a small hand pump for adding it, and I know the car must be level. The drain plug is in the bottom - so I'll drain it before pulling the speedo cable off. I'll get 2 Qts of gear oil to assure I have enough, most likely Valvoline gear 75W90 oil. Any other advice is welcome.. Many thanks in advance ...
