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 MTL 75W80 GL-4 Gear Oil. Red Line engineered this gear oil to provide your drivetrain with optimal lubrication properties, friction resistance, and overall longevity. This is a fully synthetic GL-4 rated gear oil that contains major formulas that add extra protection against friction while promoting better shifts.
DETAILS:
- Popular for BMW, Honda and Acura, Ford Focus, late-model Mini Cooper, Land Rover/Range Rover LT77S, Dodge & Jeep NV1500, NV3500, and NV5600 truck transmissions
- Popular replacement and improvement over Gm Synchromesh (# 12345349), Auto-Trak II (12378508), and Chrysler spec MS9224
- Safe for brass synchros as it lacks the reactive sulfurs found in most GL-5 oils that can cause damage
- Offers quicker shifts and has a perfect synchronizer coefficient of friction
- Eliminates notchy shifting even when cold
- High-performance gear protection and longer synchro life
- Satisfies the gear oil viscosity requirements of 75W, 80W, and motor oil viscosities of SAE 30, 10W30 and 5W30
- Recommended for GL-1, GL-3, and GL-4 applications as well as where most special synchromesh fluids are specified
- Appropriate coefficient of friction for most manual transmission synchronizer (other's synthetic gear oils are often too slippery for proper synchro engagement
- Works well for both high-mile and low-mile transmissions
- Sold individually in a 1 US quart container
WHY WE CARRY THIS
We only list parts we’d run ourselves or recommend to a friend building a real car. If it feels vague, unverified, or inconsistent, it doesn’t make the cut.
- Fitment-first mindset — no “universal” roulette
- Brand reputation matters — we favor proven manufacturing
- Support that actually responds with real answers
WHAT TO EXPECT
This is the clean path: correct fitment, clean install, and results that match the intent.
- Install-ready experience with correct mounting where provided
- Finish that holds up to real driving, not just photos
- Selections on this page drive the exact fitment shipped
TRUST, BUILT INTO THE PROCESS.
Anyone can list parts. We curate what belongs on a serious build. Our goal is simple: fewer surprises, cleaner installs, and confidence when you hit “Buy.”
Fitment checked
We prioritize vehicle-specific listings and clear selection logic so you’re not gambling on compatibility.
Brand discipline
Proven manufacturing and consistent quality matter more than hype. We bias toward what actually holds up.
Real support
If you have a question, you’ll get a human answer that helps you finish the build — not a copy-paste shrug.
