Transmission Repair & Service

Harsh shifts, fluid leaks, slipping, warning lights — most transmission problems don't need a rebuild. We diagnose first, repair what's actually broken, and tell you honestly when it's more than that.

What We Repair & Service

Manual, automatic, classic or modern — the full drivetrain, diagnosed before a single part is ordered.

🔍

Diagnosis First

Scan, road test, fluid check and pressure tests before anything comes apart. You get the findings in writing — then decide.

🛢️

Fluid Service

Correct-spec fluid and filter changes for automatics, manuals and diffs. The cheapest transmission insurance that exists.

Solenoids & Electronics

Shift solenoids, sensors, valve body electrical faults, TCM issues — many "dead gearbox" symptoms are a €200 electrical fix.

🥊

Clutch Replacement

Clutch kits, flywheels, hydraulic release systems — single-mass conversions and performance clutches for tuned builds.

💧

Leaks & Seals

Pan gaskets, output seals, cooler lines, converter seals — fixed before low fluid turns a seal job into a rebuild.

🔩

Full Rebuilds

Needs more than a repair? That's our Transmission Rebuilds service — full overhaul, upgraded internals, 12-month warranty.

Repair or Rebuild? We Tell You Straight

The most expensive sentence in this trade is "might as well do everything". Our approach:

  • Diagnose before quoting — no rebuild quotes from a phone description
  • Findings with photos — you see what we see, with measurements
  • Repair when repair is enough — a solenoid job stays a solenoid job
  • Rebuild when it isn't — with itemised options, including exchange units
  • The £50 seal test — if a cheap fix has a fair chance, you hear about it
  • Written record either way — findings, work done, parts used

Book It In If You Notice

Catching these early is the difference between a service bill and a rebuild bill:

  • ⚠️ Harsh or delayed shifts, hot or cold
  • ⚠️ Slipping under acceleration
  • ⚠️ Red or brown fluid spots under the car
  • ⚠️ Transmission or check-engine warning light
  • ⚠️ Whining that follows engine or road speed
  • ⚠️ Burnt smell after driving
  • ⚠️ Clutch pedal feel changed — high, soft or spongy
  • ⚠️ It's simply been 60,000+ km since the last fluid service

Common Questions

Usually yes — with one honest caveat. On a healthy or mildly-worn unit, correct fresh fluid improves shifting immediately. On a severely neglected automatic that's already slipping, a fluid change alone won't reverse worn clutches — we'll check the fluid condition and tell you which situation you're in before you spend anything.

Short, gentle driving to reach us is usually fine if shifts feel normal — but a flashing light, slipping or burning smell means stop and call. Continuing to drive a slipping automatic turns a repair into a rebuild, sometimes within a single journey. Collection is available if you'd rather not risk it.

Rough guide: rpm rising without road speed (in any gear) points to the clutch slipping; grinding, popping out of gear or one specific gear misbehaving points to the gearbox. Our diagnostic road test settles it in minutes — and the written findings mean you're never paying to "try something".

Yes — fluid services and external repairs on most DSG/DCT and CVT units, using the exact specified fluids (these boxes are unforgiving about fluid spec). Internal DCT/CVT mechatronics work depends on the unit — ask with your model and we'll tell you honestly what we take on.

When worn internals are the cause — burnt clutches, worn synchros, damaged hard parts. If that's what the diagnosis shows, you get both options priced: rebuild of your unit (with upgrade options) and, where available, an exchange unit. The choice and the paperwork are yours.
