Mahindra Scorpio Gearbox upgrades!
If your Mahindra Scorpio (SUV or Pik-Up) is struggling in 5th or 6th, you’re not alone - and you’re in the right place. Overdrive gears take the biggest beating on our long South African highways. When they start to wear, you’ll feel it: the gear pops out under load, there’s a high-pitched whine, or you notice vibration and metal flakes in the oil. Left unattended, costs multiply fast.
At Mayfair Gearbox, we don’t just repair the symptom - we remanufacture the transmission with upgraded gearsets and stringent quality controls so your Scorpio keeps doing what Mahindra designed it for: efficient, reliable work. Just like us.
Why 5th & 6th Gears Suffer on the Scorpio
- Highway torque & load: 5th/6th (overdrive) carry sustained torque at lower RPM, accelerating wear on gear teeth, hubs and bearings.
- Heat & lubrication stress: Long-distance cruising plus heavy loads or towing can thin the oil film, increasing wear on overdrive meshes.
- Progressive symptoms:
- Popping out of 5th/6th under throttle or on decel
- Whine/rumble that grows with road speed
- Notchy shifts or baulking into the top gears
- Glitter in drained oil or on the magnetic plug
If you’re experiencing any of the above, stop driving hard in those gears and book an assessment. Early intervention often saves collateral damage.
The Mayfair Difference: Upgraded Gearsets + 100% Dyno Tested
When we remanufacture a Mahindra Scorpio transmission, we replace the affected overdrive components with the latest, upgraded gearsets from Mahindra and complementary parts to improve longevity and shift quality.
What we upgrade/replace during reman
• 5th & 6th gear pairs (revised tooth profiles & materials where applicable)
• Synchro assemblies (rings, hubs, sleeves) for crisp, low-wear engagement
• Bearings & races (high-spec replacements, correct preloads)
• Seals & gaskets (OEM-equivalent) to stop future leaks
• Selector forks/rails inspection and replacement if out of spec
• Endfloat & backlash set precisely to spec for quiet running
100% dyno testing - every single unit
We dynamometer-test 100% of these transmissions through controlled load, speed and thermal cycles. We verify:
• Noise & vibration across all gears
• Shift quality (engagement forces, timing)
• Leak integrity under temperature
• Gear mesh behaviour at steady-state cruise (where 5th/6th live)
Only dyno-certified units leave our facility.

Mahindra vehicles are exceptionally efficient and reliable - and our remanufacturing approach is built to match.
Same-Day Turnaround? Ask for an Exchange Unit
We stock exchange units for popular Scorpio applications so you can get back on the road the same day (subject to availability and model match). We’ll take your core, install the dyno-tested reman, and you’re rolling - fast.
Nationwide support: We handle courier logistics for workshops and fleets across South Africa.
Typical Signs You Need Us
- Pops out of 5th or 6th under load
- Whine/rumble that’s loudest in top gears
- Hard or crunchy engagement into 5th/6th
- Oil leaks and/or metal particles in oil
- Recently, towing or heavy-load usage with new noises after
If you’re unsure, bring it by. A quick road test and oil inspection tells us a lot.

- QC sign-off:
Transmission leaves with a dyno report and warranty.
FAQ
Q: Can I keep driving if 5th/6th are noisy or pop out?
A: Best not. Continued use can damage shafts, hubs and bearings, raising costs.
Q: What’s the turnaround time?
A: With exchange stock it’s often same day. Otherwise, a standard reman cycle applies - speak to our team for current ETAs.
Q: Do you only fix the failed gear?
A: No. We treat root cause and fit upgraded overdrive gearsets with new synchros/bearings, then dyno-test 100%.
Q: Do you service both Scorpio SUV and Pik-Up (2.2 mHawk)?
A: Yes - talk to us with your VIN so we supply the correct spec.
Q: Do you offer a warranty?
A: Yes - all remanufactured units are warranty-backed. Details depend on application; we’ll specify on your quote.
