Don't bother with using syn***ic in the transaxle. Use a quality dino and replace it every 30K.

Read carefully. I'm on my third Max, all have been manuals. What you want is from Specialty Formulations and is called MTL-P I believe. It's by far the best I have tried.

well i had Redline MT90 in there when i did my short shifter than my drivers side axle seal started to leaking so i needed to replace it but i could not get any Redline MT90 on such short notice. The best i could find locally was Mobil 1 75W90 Synthetic so what i am running now is 3 quarts of Redline Mt90 and 2 quarts of Mobil 1 synthetic. I should be getting My oder of redline oil this week so i will drain the whole thing and re fill it,

I had MT90 in mine for a few months. IMHO, SF is VASTLY superior.

in a MT, dino is better with Redline or Amsoil being the exceptions. I tried M1 oil in a 96 altima and it shifted like crap. Redline shifted like a dream though.

AMSOIL recently introduced a new 75w-90 GL-4 lube specifically designed for use manual transaxles and other applications requiring the use of a GL-4 gear oil. See my post in the Group Deals section of the forum. I offer all AMSOIL products for dealer cost...cost for the new gear oil is $6.20/qt ($7.80 retail) plus your local sales tax and shipping from the nearest AMSOIL Product Center.

That's what I'm using on my tranny, purchased locally in Portland.

For God sake's, dont put anything labeled GL5 in your tranny....GL5 is made primarily for non-shifting gearboxes (ala transfer cases and differentials) and the additives in GL5 oil will over time soften (hence ruin) the soft metals in a transaxle -meaning, the brass/alloy synchros.

Nissan trannies require GL4 oil ONLY. Only only only. If you put the vaunted Mobil 1 GL5 liquid, yes, it will shift wonderfully -for a while, at least...

Whatever you do, don't use Mobil 1 Synthetic gear oil. I tried it one both my 1993 and 2000 Maxima. The shifts were hard than usual until I switch back to GL-4 oil from NAPA. The Mobil 1 Syn causes the extra wear to the brass synchros in our gearbox.

I 2nd this, it will shift like absolute crap. dino GL-4, redline mt-90, or amsoil only. Synthetic in general is too slippery and prevents adequte synchro performance.

I have Amsoil gl-4 75w90 in my MT right now and several of my friends have MT90 in their trannies. I recommend both. I am glad Amsoil finally brought back the fluid for our cars.
