Manual transmission fluid
I went to Autozone looking for some gl-4 gear oil for my transmission and I couldnt find any at all, all they had was (gl-5,gl-4,gl-3)compatible gear oil. I asked someone that works there and they told me that the gl-5,gl-4,gl-3 one they had would work just fine in our transmission. I just need some feedback, is it ok if i use this oil instead of the gl-4 only oil?

i wouldn't use it
im no senior member or anything,,,actually im new here too, just got a maxima a couple of months ago and have been on here just about everyday since....i searched for a long long time on this and from what i have read you dont want to use the gl4 gl5 ect blends....you only want straight gl4....i guess there is dino" old school regular "dont know where you would get it " and then most people say redline mt or amsoil.....i ended up going with the amsoil ... you can get it from a member on here pretty cheap shipped....just do a search for amsoil gear oil....and make sure you choose relevancy when your searching that should help out alot....I didnt know that for a while.....Now i haven't put it in my car yet because im getting cv axles next week and I dont wanna lose any when those are changed. ...but i actually found a local dealer in my area....googled it........however i think it was cheaper from the guy on here ...his name is talking horse or something....again just search amsoil gear oil and you'll find him.....you want 75w 90 i do believe....and gl4 only says it right on the bottle.

GL-4 ONLY !!!!!!!
GL-5 will eat the syncorz in the trans. It's also thicker, heavier, and has different heat tollerances. GL-3 is not adiquit either - again, different heat toll.
You can use any old GL-4, of course reccomended is as stated above - Amsoil, or Redline (or Royal Purple is also a popular one here). You can look at other auto parts stores, but you might be better off ($$ wise) to order what you'll need. You will need 5 qts - only uses 4.5 though.
Out of total curiosity - why do you need MT oil ???? Leaking ???
You can see the link in my sig for more 'detailed' trans issues. It's my write up on rebuilding / R+R / + clutch job.

Use straight GL4 gear oil, not one of those blends and change it every 30,000 miles. Synthetic gear oil should be good for 50 - 60 k.
Not sure if there are Pennzoil lube joints where you are but in British Columbia they carry straight GL4. The stealerships don't even carry straight GL4 locally.

Hey OP, I put Redline in my transmission at 100k and it's been amazing. No leaks to speak of, and if anything my shifts have gotten smoother. I would 110% recommend it. I had to go to a smaller, less nationally known car store to get it.
It's worth the extra time and effort to get a good synthetic. It's been amazing.
. I'm now at 154k and it's still as smooth as when I first put it in.

Back in the day went I decided to switch to a synthetic gear oil, I chose Amsoil.
When replacing a clutch a drained it andcouldnt find any Amsoil local so I put in the Redline. I noticed a difference immediatly. My shifts werent as smooth as they were with the Amsoil. A few weeks later I went back to the Amsoil and have used it ever since.
As mentioned before Talking horse will give you a great price on the Amsoil.

you can use GL5, but you'll wear out your synchros faster. we actually used to OK it for use in GL4 transmissions that were going to see heavy duty racing applications. it protects the gears better because it has significantly more EP agents in it. but those EP agents will also wear out soft metal synchros faster (specifically how much faster I don't know, but we only recommended it for use in transmissions where the act of racing itself would wear out the synchros quickly anyways, necessitating rebuilds and replacement of those synchros more often than a street car would need).
in short, you can use it but there's no reason to in a street car. just get some regular GL4.

Agreed! Amsoil is what I have been using as well - got it from Talking Horse in fact. He will give you a good deal and it really is the way to go.
Nealoc - interesting thought on the GL-5 in a 'racing' application.
I would be sort of curious (to a degree) to find out how much quicker the 5 breaks down the brass of the syncroz. This sounds like a job for Mythbusters! Let's call em'. hehehehe

DO NOT use GL-5 if you like your synchros. The additives will form too strong of a sacrificial bond with the soft metals (brass synchros) in your transmission and slowly degrade them. Good reading for this subject: http://www.widman.biz/uploads/Transaxle_oil.pdf

Alright, I've just changed the Trans fluid (Amsoil 75W-90) for my 5 speed.
I have no idea why, but now shifting into 2nd is not smooth at all. I thought maybe if the trans would get warmer this hard shifting would go way, but no.
Anyone else having this issue?

i've found a few mom and pops shops around here in socal that sell straight gl4, its made by crc iirc...
kinda ot.. when i used to work in a shop as a lube tech, we would put gl5 or whatever was cheapest into cutomer cars. Also sometimes 20w50 motor oil. No ill effects..

Don't know that brand. Why not look on the Redline website to see which product they recommend and just buy their good synthetic oil. It is intended for GL-4. It works quite well. Others have used it. Why re-invent the wheel?
