- CATCH IT EARLY

7 signs your gearbox
is asking for help.

If you spot any of these, get it diagnosed now. A $400 service today often prevents a $6,000 rebuild later.

SIGN 01

Hesitation or delay before gear engages

A 1–2 second pause when shifting from P to D, or R, points to fluid pressure loss in the valve body.

SIGN 03

Burning smell from underneath

Overheated transmission fluid. A sniff test from the dipstick (or under the car) tells the full story.

SIGN 05

Gear slipping at speed

RPM climbs but speed doesn't — friction plates are glazed or the torque converter clutch is failing.

SIGN 07

Red or brown fluid puddle under car

ATF leak from pan gasket, axle seal or cooler line. Easy fix if you catch it — catastrophic if you don't.

SIGN 02

Hard or jerky shifts at low speed

Clunks during 1–2 or 2–3 upshifts usually mean worn solenoids, dirty ATF or aged friction plates.

SIGN 04

Whining, humming or grinding

Bearings or planetary gears are wearing. Caught early — a bearing job. Left late — a full rebuild.

SIGN 06

Check Engine / Transmission light

P0700-series codes are gearbox specific. We read live data, not just the code, to find the actual cause.

We recommend a free inspection if you're unsure when your last service was.

❓ What’s the difference between gearbox repair, servicing, and overhaul?
– Servicing: Preventive maintenance like fluid changes and inspections
