If my manual 1995 Nissan P/U is leaking gear oil ?

can I put more gear oil in it or do I have to drain and replace all the gear oil?

You fix the leaks then drain and refill with 75/90wt GL-4 manual trans oil. If you must fill to keep running please do not use rear end grease. Sometime the shifter rubber boot cracks and leaks oil down from on top rear of the transmission. Don't over look that leak. 2 wheel drive 4.25 pints and 4x4 10 3/8 pintsIf my manual 1995 Nissan P/U is leaking gear oil ?
if it is leaking oil you have a bad seal either the front or the back


the back you have to pull the drive line out the front you have to pull the whole thing out you can put more gear oil in but that will leak out too draining and replacing gear oil on a regular basis like the oil in your engine looses it viscosity


or it slippery ness over time of heating and cooling so you have to replace it annually once year depending on how much you drive if you don't fix it it will cost you see links below first two are from parts America third link is how much a rebuilt trans is going to cost you a new trans is way more than the truck is worth the gear oil does a number of functions it cools the gears keeps them from making noise and allows for smooth shifting and lubricates the gears if you let i continue to leak and do nothing your going to need a another trans, for the cost of the seals well worth replacing if they are leaking


when your truck dies and your planning on getting a new truck then don't bother when its dead your out thousands better off getting another truck


if you can't afford another rig you better replace those seals otherwise your going to be putting lots of oil in on a regular basis how to check when its full stick your finger in the hole to the fist bend on your finger make sure the truck is not running, you should feel oil on your finger at the first bend if don't its low but don't over fill it either that can cause it to leak out in the first place forces the seal out.





hope that helps
