Transmission Fluid Pan Specification Example for Utility Trailers: Drilled and Slotted

This is a worked specification for transmission fluid pan in a drilled and slotted programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.

The drilled and slotted version exists because the duty cycle on utility trailers is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a supplier who changed material without saying so.

How the example is built up

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — Bronze, in this example.
  3. List the dimensions that are actually controlled and the tolerance on each.
  4. Name the finish and what it has to survive.
  5. State the inspection level and who pays when a lot fails.

Processes involved

  • electroplating
  • injection moulding
  • surface grinding
  • shot blasting
  • sintering
  • laser cutting

Where this example applies

Programmes that run drilled and slotted most often specify this build for utility trailers. Related applications include dealership service, fleet maintenance, city buses, passenger cars, municipal fleets.

Checks before packing

  • Dimensional report against the approved drawing.
  • AQL 4.0 sampling on the finished lot.
  • Finish inspection under agreed lighting.
  • Carton drop test on the first lot of a new packing specification.

Questions buyers ask

What testing is included?

Standard lots ship with dimensional and hardness reports. REACH documentation is issued with the shipment when your market requires it.

What happens if a lot fails inspection?

The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.

Can the specification be held on file?

Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the REACH-compliant build instead of a fresh interpretation.

How long does sampling take?

Samples leave the factory in 7 working days, and each revision round adds about 3 days once you have seen the first piece.

Share a sample or a drawing and we will quote against a written specification, not against a photograph.
