Service · Transmission Test

Diagnosis before disassembly.

Most transmission complaints are not what they first look like. Our Multi-Check is a methodical four-stage assessment — stationary, road, electronic and written — built to find the actual cause before any case is split or any part is ordered. It’s how we make sure you only pay for work you actually need.

The full Multi-Check is free.

You drive in. We diagnose. You leave with a written assessment — and a price, if anything needs doing. If nothing’s actually wrong, you pay nothing and you keep the peace of mind.

The four-stage Multi-Check

A system, not a hunch.

Each stage rules things in or out. By the end, we’re not guessing — we know what the transmission is doing, why, and what (if anything) needs to be done about it.

  1. 01
    Stage one

    Stationary test

    Engine running, transmission warm, parking brake on. We engage every gear position and check for clean engagement, abnormal RPM behaviour, leaks, fluid colour and condition, and any visual or audible irregularity before the car has moved an inch.

    • Fluid level and colour against a clean reference
    • Gear position engagement quality
    • Idle behaviour in Drive and Reverse
    • Pan and case visual leak inspection
  2. 02
    Stage two

    Road test under load

    The transmission only behaves like itself when it’s actually working. Light throttle, hard acceleration, downshifts, kickdown, cruise — we drive the car through every condition the gearbox sees in normal use and pay attention to what it tells us.

    • Shift timing — early, late, hesitant or harsh
    • Slipping or RPM flare between ratios
    • Torque converter lock-up engagement and release
    • Noises that appear under load and disappear at idle
    • Behaviour from cold and at full operating temperature
  3. 03
    Stage three

    Electronic scan & live data

    Modern automatics are run by the transmission control unit, and that unit keeps records. We pull stored fault codes, watch live sensor data while the car runs, and compare actual values against manufacturer specification — every solenoid, every speed sensor, every pressure reading.

    • Stored and pending TCM fault codes
    • Live solenoid duty cycles and pressure data
    • Input vs output shaft speed comparison
    • Adaptive learning state and reset where needed
  4. 04
    Stage four

    Written assessment

    Findings, plain language, on paper. What’s actually wrong, what’s likely to fail next, what we recommend now and what can wait. If a service is enough we’ll say so; if a rebuild is the right call we’ll explain why — and itemise it before we touch anything.

    • Clear summary of findings, written in plain English
    • Recommendation: service, repair, rebuild or no-action
    • Itemised quote with parts and labour, if applicable
    • No obligation — you take the report and decide
What we’re looking for

If the car is doing any of this, bring it in.

A symptom rarely points to a single cause — that’s the whole reason for the Multi-Check. But these are the patterns we hear about most, and what they typically mean we’ll be looking for.

Drivability

Slipping under acceleration

Engine revs climb but the car doesn’t accelerate the same way.

Likely areas: worn clutch packs, low fluid pressure, contaminated fluid, or torque converter lock-up failure.

Shifting

Harsh or delayed shifts

Gears slam home, hesitate before engaging, or shift erratically.

Likely areas: valve body wear, solenoid faults, sensor data out of spec, or adaptive learning corrupted.

Sound

Whining, humming, grinding

A noise that wasn’t there before, often louder under load.

Likely areas: bearing wear, pump failure, planetary gear damage, or low fluid level starving the pump.

Visible

Fluid leaks

Reddish or brownish patches on the driveway after parking.

Likely areas: pan gasket, output or input shaft seals, cooler line fittings, or cracked case.

Electronic

Warning lights or limp mode

Check Engine, transmission warning, or the car limited to a single gear.

Likely areas: stored TCM fault, solenoid circuit, speed sensor, or thermal protection event.

Behaviour

Won’t engage gears

Car doesn’t move in Drive or Reverse, or feels delayed engaging.

Likely areas: very low fluid, internal seal failure, worn pump, or a faulty range/inhibitor switch.

None of this is a diagnosis — it’s a starting point. A real assessment requires the car in front of us.

What you leave with

A written report. Honest options. No obligation.

The whole point of the Multi-Check is that you walk out knowing what’s going on with your car — whether you decide to have the work done with us or not. The report is yours.

Multi-Check Report Sample — what you receive
  • Findings — in plain English What the transmission is doing, what we observed, what it likely means.
  • Recommendation Service, repair, rebuild, or no-action — with the reasoning.
  • Itemised quote (if applicable) Parts, labour and timeline before any work begins.
  • Fault codes & live data summary What the TCM is reporting, in human terms.
  • Take it elsewhere if you like The report is yours to use however you choose.
Walk-in welcome

Same-day diagnosis on most vehicles.

Pull in, hand over the keys, grab a coffee. Most Multi-Checks are completed inside an hour. You leave with the written report — and, if nothing’s actually wrong, with the time and the certainty back.
