DIY Transmission Flushing System - Description

This DIY Transmission Flushing System was constructed using parts which are readily available from any hardware store. A transmission in-line connector and pipes was obtained from a wrecked M-B.

A parts list is:

  • two off 5L garden spray pump pressure bottles,
  • rubber tubing,
  • reinforced vinyl tubing,
  • brass coupling fittings,
  • hose clamps,
  • aftermarket in-line transmission fluid filter, and
  • a used in-line transmission connector and pipes.

The in-line connector and pipes from the wrecked M-B were cut and fitted to the clear vinyl tubing and became the connection points to the vehicle being serviced.
