DeviousPsycho620 Posted February 19, 2013 Report Share Posted February 19, 2013 On any 5 speed manual, have the vehicle on a level surface. Pull the fill plug. It should be right to the bottom of the fill plug. Just stick your pinky in and you should be able to feel it. Quote Link to comment
JoeCool Posted February 19, 2013 Report Share Posted February 19, 2013 What he says, also the fill plug is on the side of the transmission. Drain plug is on the bottom. Quote Link to comment

On a 521 or D21 there will be a plug about half way up the side. The 521 likely has a large square end on it that a crescent wrench will fit on. Maybe fit a small length of pipe over the handle to increase leverage. On the D21 the plug most likelt has a square hole in the plug that a 1/2" ratchet or breaker bar will fit in. Where is the leak? If at the front it could be the rear seal on the crank on the back of the engine. Possibly the front seal of the transmission but more likely the motor. If at the rear of the transmission it's just the rear seal for the driveshaft and cheap and easy to do. If not sure, power wash and watch to see where the oil starts dripping. Not too much sense not fixing a leak. My advice is to simply replace the oil with new. If you have never done it, it's extremely likely that it may never have been done, as second owners really don't give a shit about maintanence. 4th and 5th owners even less. The drain bung is on the bottom and most transmissions hold only 2 liters of oil. USE only GL-4 80W90 gear oil. Don't be talked into GL-5 oil by some kid that doesn't know that it will corrode (over time) your brass synchro rings. If you can't find any be sure that what you use is marked "Yellow Metal Safe" or "sofe to use with brass" GL-5 is made for use in differentials and contain 50% higher levels of sulphur anti scuff additives. Might be a good idea to replace the differential oil too. Quote Link to comment

Ill make sure to only buy GL4, or anything yellow metal safe, i know kids at autozone always try to get me to buy other crap thats not good for my truck. I've been meaning to ask you, you had mentioned to me in another thread to use delo 15w-30 i think it was, i noticed we use that oil in our diasels at work, and it says diasels use. Is it safe to use that oil in my l20b? Quote Link to comment
datsunaholic Posted February 20, 2013 Report Share Posted February 20, 2013 I've been running Delo 400 15W40 for a couple years. If you look on the bottle, it says CI-4 Plus (that's a diesel rating) but you'll also see SL, SJ or some other 2-letter combo stating with an S. That's actually a gasoline rating. Delo 400 meets both, but currently not SM/SN ratings which are LOW ZINC ratings and are not good for your camshafts. Chevron does rate the Delo 400 for gasoline use, for engines older than the 2004 model year (that's when the SM type was set). Quote Link to comment

So it is safe to use, even though this has the low zinc rate? is it possible to add zinc to help it? Quote Link to comment
datsunaholic Posted February 20, 2013 Report Share Posted February 20, 2013 Delo has higher zinc than SM/SN oils. At least currently. All oils are going away from it, SN has the least and that's pretty much the only "gasoline" oils you can find other than racing oils nowadays on the shelf. Quote Link to comment
Nismo1970 Posted February 20, 2013 Author Report Share Posted February 20, 2013 good to know. I'll make sure to pick some up for my next oil change. :) sorry for the newbish questions, i don't know much about the oil specs, zincs n stuff. i jus want the best for my engine lol but don't we all lol Quote Link to comment
Dawa Posted February 20, 2013 Report Share Posted February 20, 2013 replaced my trans oil a few weeks ago. everyone was saying that the only place to find gl 4 is at napa (made by sta lube.) well after goinf to oreilly, pep boys, autozone, and a few others, i can attest to it. so save yourself the gas and go straight to napa. its expensive (25ish or more) but its enough fot about 2 jobs. buy yourself the screw in hand pump to make the job easier Quote Link to comment
graveltrapp Posted February 20, 2013 Report Share Posted February 20, 2013 Redline mt4 90wt for the tranny (gl4) W75/90 for the diff Quote Link to comment
Dawa Posted February 20, 2013 Report Share Posted February 20, 2013 ^are you speaking from experience? read on some other random car forums of guys having bad luck with redline even though it was supposedly GL 4/yellow safe Quote Link to comment
Stupid_fast Posted February 21, 2013 Report Share Posted February 21, 2013 ^are you speaking from experience? read on some other random car forums of guys having bad luck with redline even though it was supposedly GL 4/yellow safe With the ZX box, I've used royal purple synchromax, bearing noise and okay shifting, royal purple gear oil It was grinding into 2nd at high RPM shifts, with redline MT-90 less bearing noise and smoother engagement. Redline MT-90 seems to be the choice for Z guys. Not sure about other nissan gearboxes. Quote Link to comment

I don;t have a z, ive got a 521, with an L20b and a 5 speed tranny, newer diff, i'm not exactly sure which tranny or diff. Any way i can check so i know for future referance and jus so i know lol.

graveltrapp Posted February 21, 2013 Report Share Posted February 21, 2013 The older boxes should use a GL4 formula. It is not as common as GL5. It is either the off brand stuff or Redline. I have always used Castrol Products whether it be Brake, Gear, or Motor oil. But because of the new info coming to me about the additives in the newer GL5 formulas, to get a decent GL4 I had to try the Redline MT90. As stated elsewhere, the rear diff will take the 4 or 5 so I went with the standard Castrol 75w90 GL5 for it. Although the Redline is double the price, Both the box and diff each use less than a quart a piece so at $15 for the Redline I did not lose much sleep. The jury is still out on the overall performance as I have not been doing much driving with it yet. This weekend I will be going down to the Olympia meet and that will be over a 100 miles in an afternoon. I will report back after that. Quote Link to comment
