Automatic gearbox specialists

Considering a remanufactured gearbox?

A defined rebuild to a spec is not a used box with a wash. If the word remanufactured is on the quote, ask for the process.

  • Quoted reman, recon and used as if they were the same?
  • Want measured parts, not a lucky second-hand unit?
  • Still not sure your own gearbox is beyond repair?

A remanufactured gearbox should be stripped, measured, and built to a specification with wear parts replaced as a process, not as a maybe. It is a different claim to reconditioned. We still start with your unit, because many automatics do not need a full reman.

If nobody can tell you what was measured, it is not a remanufacture you can rely on.

What is a remanufactured gearbox?

Remanufactured, done properly, means the automatic gearbox is built back to a written spec: clutch packs, gearbox bearing, seals, and inspected gear sets. That is closer to a full rebuild than to a used reconditioned gearbox.

Your own gearbox, opened after a diagnostic check, can be remanufactured or rebuilt in house. A swap is not automatically better.

Fix the transmission cooler and the cause. A beautiful reman behind a leaking radiator will die the same death.

A remanufactured unit still fails if the cause is left in the car

Coolant in the oil, a blocked cooler, a missed TCU update or a pump that was never checked will take the next gearbox too. We do not bolt a reman on and hope.

When remanufacture is in the conversation

If any of these sound like your car, do not wait for it to fail on the road.

Multiple packs burnt, gear set still good

A spec rebuild or reman of your unit.

Metal through the pump

More than a valve body.

No Drive after a bang

Strip and measure. Then decide.

Quoted reman with no process

Ask for the parts list.

Dual-clutch, only packs worn

Often not a reman of the whole box.

Repeat failure on a used unit

Process and cause, not another lucky dip.

How a proper reman differs

Parts are measured against limits. Wear items are replaced because the process says so, not because they looked 'ok-ish'.

adaptation after fitment is part of the job on modern automatics.

1

Diagnose and strip

Know what actually failed.

2

Measure and replace to a spec

Not a wash and a prayer.

3

Refit, adapt, road test

And fix the cooler if that killed the last one.

Reman and rebuild work we do

We remanufacture or rebuild automatics when that is the honest job, and we repair them when it is not. The label on the quote has to match the work.

  • Diagnosis before any reman talk
  • Measured internals, not vague labels
  • Cause of failure fixed in the car
  • Adaptation and test after fitment

Straight answers from a transmission specialist.

It should be, if the process is real. Ask what was measured.

Often yes, plus adaptation.

No.
