Please post your impressions of the MaxGear. I personally had good luck with it in an '03 coupe (compared to the OEM fill). How does your '04 box behave with it?

Mika,

Well, I drove around last night and I really like both the Royal Purple Engine oil and the MaxGear.

The shifting is still notchy, but you don't get that metal on metal sound and feel when shifting. More like the shifter is gliding over a notch. Smoother.

The guys that changed it said they found some metal splinters in the tranny oil drain area. Not sure what that means for the tranny, but hopefully the wear will be reduced with the RP.

So I really like the MaxGear and I think the difference is definately noticeable.

The engine oil totally rules. Deep growl from engine. Hell ya!

 

any more reviews?

 

Is it necessary for me to change my tranny oil? I have an 04 base Z with 3500 miles, and i dont have any tranny problems. I dont know much about changing the tranny oil.

Thanks

 

Royal Purple MaxGear is the way to go.. been using it for 34k miles, better than Redline imo.

if you don't have any problem with tranny, then don't change it..

 

So there are some that like Royal Purple. Some that like
Redline. Sounds like both make the shifting a little smoother,
but neither really gets rid of the 1st-2nd gear grind when cold?

Does anyone else have any input?
Has anyone tried BG Syncroshift?

 

BTW, I found this on a Subaru forum:

Redline MTL -- Great for manual transmissions, hot or cold. A 70W80 GL-4 gear oil for use in manual transmissions on both street and track. Provides excellent protection of gears, synchronizers, and bushings. Shifts well when cold and allows for fast shifts when warm.

Redline 75W90 Gear Oil -- A GL-5+ and GL-6 spec oil, preferred for use in conventional and LSD differentials. Contains limited-slip friction modifiers for decreased noise and better wear from clutch-type LSD units. Suitable for street and track.

Redline 75W90NS Gear Oil -- A GL-5 oil, designed for conventional differentials, but can be used in clutch-type LSD units for increased locking rates, leading to reduced wheelspin. Not recommended for street-driven LSD units!

Redline MT-90 -- A 75W90 GL-4 gear oil recommended for use in manual transmissions on the track. Provides excellent protection of gears, synchronizers, and bushings at higher temperatures. Not recommended for street use in cold climates.

MT-90 is "not recommended for street use in cold climates"??

 

My order of RP just arrived today, will be switching both tranny and diff to 75w90 Max Gear fluid. Will post my impressions next week.

 

RP will make your gear little sticky. Especially when cold. The best fluid out there for the Z's are OEM or Redline 70w-80.

I used RP before and from my experience, it made my gear sticky.

just my .02 cent.

 

i had a really tough time putting my trans in 5th gear (it was like that from nissan when they put in my new trans) i swapped the fluid to the royal purple, and instanly, the trans glides into 5th now. so it made a very noticable improvement for me.

 

You sure it wasn't the guide plate that was making hard for you to shift to
5th.

When I had my old Z (Coupe Touring) it was really hard for me to shift to 5th and when I adjusted the guide plate, it made my shift to 5th lot easier.

Just my thought.

 

I've had the RP in my tranny for a while now and I still like it. Of course, I can't remember what my car was like before it. I also put RP in the rear differential. I never noticed any stickiness in tranny, but I never tried Redline to compare it to. I also occasionally get a little trouble getting into 5th, but that could be my guide plate as I realigned it myself when installing my short shifter. I probably just need to adjust it.

Just some extra comments.

 

From what I have heard from other forum members, RP & Redline are pretty much the same. After 1k on Redline, shifting is much smoother... 2nd to 3rd & 4th to 5th feels like a straight line instead of multiple movements. I am very satisfied after switching to synthetic.

 

Redline MTL(70w-80) is little thinner than OEM/stock(75w-85) tranny fluid and Royal Purple(75w-90) is little thicker.

 

Redline also carries 75W-90, it is their MT-90.

I mixed my own little concoction when the Z went in to get the tranny oil changed. I used 2qts MTL (70w80) & 2qts MT-90 (75w90). It's just enough for a perfect coefficient of friction to shift faster and it also takes away any notchiness in the gearbox. I love this combination and will do this in the next change.

 

Please forgive the uneducated question, but how many quarts for the tranny and for the diff?

 

alil under 4qts for the tranny. a tad bit under 2 qts for the diff.

 

I hope I ordered enuff RP (5 qts.) for both tranny & diff., I'll know tomorrow when I make the change.

 

You might need to order 6 qts to be on the safe side. It's always better to have more than less.

 

RP Max Gear in both tranny and diff. made a huge difference. Shifting is so smooth now, used to be pretty notchy shifting from 1st to 2nd. Very quiet in all gear shifts. Glad I didn't wait, at 30K the OEM fluid didn't look to bad, but I am glad I am now totally synthetic thru out. Should pay dividends, as I plan to drive it only as a pleasure driver, no more daily drive stuff for the Z. BTW, just put in NGK Iridium Spark Plugs as well.
