I can't say for sure on a 4 spd car - but most cables I've lubed you have to extract it from the dash. The old grease inside dries up hardens and then tends to growl. Getting them back in can be very challenging. Basically you remove the cluster, pull the cable out of the tube, clean it up as best you can, wipe it down with a good coat of grease (wheel grease sticks best and stays put), work it back into the tube until it seats in the trans gear properly (you may have to rotate it some). I don't know that you could pull the cable out from the trans side....I wouldn't think so, as I recall the head on the speedo side is fixed to the cable and the trans side the gear just rides on the squared off end of the cable....
