So I know that the Mitsu LSD gear oil is the perfect fluid for the t-case, but I've heard that the Redline heavyweight shockproof (red) is better for a drag racing situation. I've also seen some people (even friends of mine) with failures when running Redline products (that aqua blue stuff) in their Evo transmissions, so it has made me kind of skeptical of Redline. What do you guys think?

Thanks
William

 

I've also see alot of people talking about Amsoil on here, but I just haven't seen any proof that it is any better than the fluids mentioned above (that is for transmission and t-case).

 

I never used Redline only OEM then I changed to Amsoil back in June 09 never looked back the tranny and TC run nice and smooth. I drag and daily beat the hell out of my car and I have no issues. I do know of my buddy who ran redline and somehow still blew up his spider gear.

 

you dont see proof,, iam not sure what more than proof you want other than alot of folks using it and stating that there tranny smoothed out.

at the end of the day with redline you are getting a non synthetic and with AMSOIL you are getting a fully Syn oil... not to say Redline is a bad oil because it deos get the job done.

 

KEEP STOCK FLUIDS IN THERE PERIOD!! Thank me later. Call a guru, like Jon at TRE... shortly after redline shock proof, I needed a new TC.

 

I used a mix of Redline Heavy-Weight and Diaqueen in my transfercase since the first fluid change. 75K miles later it's still going strong. And I do beat on it a lot. I am however on my 3rd transmission. Maybe I shift too quickly for my synchro? :}

 

Im using Heavy duty shockproof in my TC, 30k miles and no problems.

 

how often do you race the car?

 

Then you're doing it wrong...

My personal Evo 8 has had redline shock proof in the tcase for over 70,000 miles. Been through two 6 speeds from track use but the t-case has been with me for the long-haul.

My shep stage III t case has redline heavy shockproof, been running it for over 30k and it still rocks.

 

Wow. I thought I was just lucky. I just rebuilt to 2.3L and a bigger turbo so let's see if I could blow up my TC.

 

We used Redline Heavy without any issues.. currently we use the Amsoil Severe Gear.. again no issues..

Take into consideration you have one of the, if not the fastest evo out there breaking some crazy records.

 

I only use heavyweight shock proof in the TC. My driveline has over 107k miles (over 150 1/4mile passes, 35-40 autox's and a dozen or so HPDE's) and not a single issue.

I just changed it last weekend and there wasn't a single metal shaving on my drain plug. I'll be sending my sample off to blackstone labs for analysis.

btw, doesn't john @ tre highly recommend heavy weight shock proof???

 

shep says if you're running high hp or drag/track then use the redline shock proof (red) in their TC's
