MT Gear lube?

MT Gear lube?
I'm not really willing to spend the $60-70 on Amsoil or redline for 5 qts of gear oil on my maxima...but it seems that everyone else doesnt make a GL-4 gear oil anymore and the manual only calls for GL-4 75-90. Are there any options other than the 'racing' oils or do i have to bite the bullet and spend big bux on 5qts of gear oil.

When I done my fluid change I used a product called GM synchromesh. It is a good product that makes the tranny smoother and quieter. The actual oil I used was 75/W90 gear oil. Worked like a dream.

if not, that is good info. i'll look into it next time.

All I can atone to is my experience with the product. I had no issues at all. It made my tranny shift smoother and get quieter. Use at your own risk of course but I have put the product in every manual tranny I've had and loved it.

Especially if she is single (or at least has a wimpy bf) and she messed your order up so you have to go back and talk to her and score some conversation points, just like Sims

Mobil 1 makes the tranny shift like nothing else out there, but it is GL-5 and Mobil 1 does not recommend using it. So just because it feels like it is better means squat. You could be corroding your synchros without knowing it.
There are some gl-5's out there that are backwards compatible like royal purple and motul.

Also read the description...
"Mobil 1 Synthetic Gear Lubricant LS 75W-90 can also be used in rear axles where API Service GL-4 lubricant is recommended"
I don't think rear wheel drive cars have brass synchros in the rear axles

+1 .. I think the manual calls for a fluid change around 80k or 100k.. but many drive way past that without problems. a friend drained his first time at 130k and only because tranny axle bearings were going bad. the fluid looked very clean.

For the love of god change your fluid now.
#26
I think its about time to change it anyways. Any recomendations on which may be a better oil. I was looking at redline and amsoil.. Those are the only two im interested.
#28
I have 02-6 spd w/130k+ and have never changed the gear fluid but I also don't have any problems with shifting unless I slam it into 5th. Don't really slam it into 5th that often but occasionally.

I'll pull a lot harder...when I took my 01 to Tahoe (7000ft at the passes) my car was noticeably down on power.

I just changed my fluid with redline mt-90 today and the car was a little rough feeling but im sure it will probably go away once it gets use to the new oil. I did notice shifting was smoother and the car even sounds quieter. I don't believe its ever been changed untill now.

i use amsoil gl-4 and it works amazing. I got it from Ed on here, he's a certified amsoil dealer. His member name is talkinghorse, just PM him how many qts you need and your zip code for shipping. You can even pick it up to save on shipping. i got 5 qts for like 55 bucks, might be slightly higher now.

Both plugs are on the side...top=fill; bottom=drain. The plug requires a 10mm hex head to remove (auto parts store - I got one that goes on my 3/8" drive ratchet). There is a washer on each plug...they are reusable.

thanks man. i was considering doing royal purple but switching to synthetic had me worried...have the mind frame of switching from conventional to synthetic motor oil in a high mileage car, so i opted not to. ill use redline
#40
Redline is synthetic also....also from the research i did when i originally started this thread synthetic is about the only option for maintaining GL-4 compatibility. GL-5 does NOT superceed GL-4....GL-5 is not suitable for use in a trans that contains yellow metals such as brass.
