Features & Product Details

RallySport Direct is proud to bring you some of the best lubricants in the industry brought to you by Red Line. 

This is the Red Line 75W90NS GL-5 Gear Oil. This is a fully-synthetic GL-5-type gear oil that doesn't contain the friction modifiers for limited-slip hypoid differentials. This makes the transmission synchronizers come to equal speeds more quickly, allowing faster shifting and much easier low-temperature shifting. Can also be used in racing limited-slip differentials when weak spring design causes too much wheel spin.

Recommended for Subaru manual transmissions. 

 

DETAILS:

  • Designed for transmissions and transaxles - helps to slow synchros for easier shifting across a broad temperature range
  • Popular for Subaru, Porsche, and Ferrari transaxles
  • Ideal for muscle car applications such as the Ford Top Loader, Muncie transmissions, Borg-Warner T-10 and Super T-10
  • Contains extreme pressure additives like the Red Line 75W90 GL-5 oil, but lacks friction modifiers to balance slipperiness
  • Improved copper corrosion protection to prolong synchro life
  • Helps with lock-up on weak limited-slip differentials and compatible with Red Line Limited Slip Friction Modifier for tuning slippage 
  • Also used with clutch-type LSD's in racing for maximum lock-up
  • Recommended for API GL-5, GL-6, MT-1. MIL-L-2105E and SAE J2360
  • Non-corrosive formula - safe for use with all synchro materials
  • Sold individually in a 1-quart container

    Great Product 4 years ago
    5out of 5stars

    Put this in my 2005 STi and I noticed that it shifts a lot nicer than before. I read a lot of great reviews on this product which led me to by it and I'm very happy with the decision.

    Did not work in my wrx's 5spd. Not long after I put it in I had trouble shifting gears mainly 2nd to 3rd. After about 10k I drained it out and the fluid looked terrible almost milky like it had broken down. I filled with extra-s and the trans shifts perfect again. Didn't work for me.

    No good for an STi 8 years ago
    1out of 5stars

    I recently changed the fluid in the transmission on my 2006 STi from the OEM fluid to this Redline 75w90ns fluid. Initially there seemed to be no difference, but after 4 or 5 days I began to hear a metal on metal sound coming from the transmission. After 7 days I couldn't stand the sound any longer, so I replaced the fluid with OEM fluid from the dealership. I don't know if this fluid did any damage to the drive controlled center differential (DCCD), but just to be safe I will keep the fluid OEM.

    Heard that many other people used redline in their wrx. Gave it a try, tranny shifts smoother than ever before. Would Defiantly recommend filling up with redline during your next trans flush.

    Seems to work fine 9 years ago

    I've ran a couple thousand miles with about 4 quarts of this in my WRX's tranny. Noticed it was slightly easier to shift after the change, but that can probably contributed to the old fluid. Will see how it performs now that it's getting below freezing.
