Post by **frsh13** » Wed Aug 15, 2007 10:51 am

Title says it all, what fluid should i use in my manual KA transmission. Ive heard I should use 75/90 gear oil, is this true?

Post by **Cameron** » Wed Aug 15, 2007 10:55 am

80/90 FOR diff

I prefer RedLine MT-90. Great stuff. I had a bit of a snag getting into 2nd, and switching to the MT-90 helped a lot.

Whoa, so I shouldnt use 80/90....****.

You can use any gear oil so long as it's a GL-4 type. Redline oils are GL-4...Apparently something about GL-5's additives mess with the brass synchros in Nissan transmissions. If you want to be the ultimate Nissan fanboy, head to your local dealer and ask them for manual trans fluid P/N 999MP-MTF00P(which is 75W-85 GL4).

Don't be too picky with the weights as it's not that big of a deal. I'm running Redline Heavy Shockproof gear oil in my trans and that stuff is like 75w250 or something

I'm running 85/140 lucas

I run MT-90 and it works great.

gl5 is the api service grade.It is nothing but a rating.

how many quarts are needed to fill the KA trannies?

I was thinking of getting 3 quarts of 75/90 and 1 quart of the synchromesh from royal purple. does that sound about right?

Thanks,

Tomek

HA! I use coastal 75/85w and its the heat. Its also cheaper than water. All my friends were in shock when I started filling it up, but hey, they suck and I rule. "Use some $5/oz redline fluid" they said! Then my buddy changed the fluid in his diff with some medline stuff and it whined like a sonofabitch. Replaced with coastal for $2 and SHAZAM! silent but deadly baby.

wrong... WRONG. GL-5 Oils deteriorate brass and other yellow metals, guess what most Nissan 5 speed tranny snychros are made of? Yep that's right brass.

I will "3rd" that. I swapped in Mobil 1 GL5 synthetic and I did have some grinding going into 1st, and during quick shifts 1-2 and 2-3. Put in the GL4 Redline and it saved the day. While my tranny shifts fine, I still get the occasional gear crunch. You are better off using GL4 regular gear oil than getting the wrong synthetic...

I'm sorry to bring up this old thread, but I was searching for a good dealer to purchase the Redline MT-90 fluid from.

All the online dealers are charging an a$$ load of money just to ship the stuff. Are there any chain auto parts store that have this stuff in stock?

I have been searching for about three days now. Any help is certainly appreciated!

Post by **ZOMG.SR20** » Thu Aug 06, 2009 3:23 pm

i use 75w - 90 GL5 NON synthetic if you use synthetic youll get the harsh shifting like others complain about with GL5

My local independent BMW service center stocks all Red Line products. You may want to check around w/service centers (independent are cheaper) I know BMW and VW both use Red Line products

I'm Gonna Start Using Royal Purlpe (Syncromax) I hear it's really the best...
