Fluids and LubricantsMotor oil, transmission oil, radiator fluid, power steering fluid, blinker fluid... wait, there is no blinker fluid. Technical discussion and analysis of the different lubricants we use in our cars.
I searched around couldn't find much info. I used to use this stuff in my Honda's and they shifted smoother after putting this fluid in. Has anyone tryed this stuff in their Maxima? How does it work with our trannies? It is the same stuff as the Pennzoil Syncromesh

Don't use any GM products. There not engineered for our cars It's pacifically GM and definetly not in our Trannies and other major engine components. If It's an auto tranny we they use the GL-4 and for the manuals they also use the GL-4 oil.

Are you tyring to say that we use GL-4 in auto trannies as well?
Redline MT-90 or Amsoil MTF, both are GL-4 and work well with Maxima manual transmissions. A maxima.org user (talkinghorse) sells Amsoil in the "Group Deal" forums at a great price.
redline makes gl-4 fluids that is called shockproof. it is specially designed to protect the syncros and ive heard some people put the light shockproof in. (as opposed to the heavy)

The shockproofs have too low of a friction coefficient for the synchros to do their best. I don't have hard data, but I also expect they'll put more wear on the synchros too. But Shockproof is great for gear-only diffs and dog-mesh trannys. It also stinks even *worse* than regular gear oil.
I still prefer the MT-90 and Amsoil MTG GL-4 oils. Last I checked, the Pennszoil Synchromesh is a much lighter oil than the 75w-90 recommended by Nissan.
ok thanks for the info, i have no experience with but ive heard from other people that the shockproof is suppose to add extra protection to the syncros. apparently its still not a good alternative.
i ordered a case of amsoil mtg gl-4 from talkinghorse so im looking forward to putting that in after i do my clutch work.

GM Synchromesh is the same fluid as Pennzoil Synchromesh and I've used it in my transmission and it worked just fine. MT-90 is a better fluid, but in a pinch the Synchromesh works just fine.
Shockproof is a bad idea in our transmissions. I know some people like to use it and would argue this with me till they're blue in the face, but they haven't taken apart over 700 transmissions in their time working at a high performance trans shop like I have. The results of a transmission that has been run with Shockproof for a long time are ugly. I've seen it time and time again. I would not run it in my trans.

MT-90 gets my vote. However, I also own a subaru and use redline as part of a tranny cocktail. It is 2 parts Castrol HypoyC one part redline lightweight, and 1 part pennzoil synchromesh. It has been tested in subaru trannies for years and works great. But every car is different. With my max I have had the best luck with MT-90
MT-90 is what I put in my trans, the #1 oil we recommend for the transmissions we build at the shop, and what I tell my buddies to put in their transmission. It's very good stuff.
GM Synchromesh is the same fluid as Pennzoil Synchromesh and I've used it in my transmission and it worked just fine. MT-90 is a better fluid, but in a pinch the Synchromesh works just fine.
I would not recommend people use synchromesh fluid in Nissan or other transmissions that require a GL-4 lubricant. To the best of my knowledge, synchromesh fluids are light viscosity and contain no EP additives. GL-4 applications require a certain amount of EP additives. Synchromesh fluid might seem to work fine in the near-term, but probably won't provide adequate protection.

80K miles on my ShockProof MEDIUM and I took the tranny apart to put in the Quaife and it still looked like brand new. There was no sludge, or wear anywhere inside the transmission. Car has been raced, and used as a DD also.
I nolonger have a Maxima, but I have changed that stuff every year and it was always clean and never gave me ANY issues.

I'm sure the annual changes helped a lot to keep it clean. The Shockproofs do contain suspended solids that grind down and eventually gunk things up. Of course, it's intended for racing so the end user should be changing it frequently anyway.
