Oil Pressure Testing Kit for Transmissions

This kit lets technicians verify oil pressure in automatic transmissions and engines across most domestic and imported cars and light trucks including late models. It includes two gauges and a set of adapters so the correct connection can be made for each vehicle. The durable storage case keeps every piece organised and leaves room for extra adapters or parts. It is intended for professional workshops and serious DIYers who need reliable pressure readings.

Straightforward Setup with Two Gauge Options

The large gauge covers every application in the kit and features a hang-up hook for hands-free observation while the engine runs. The small gauge is reserved for engine oil pressure where the maximum does not exceed 50 PSI (3.5 BAR) and gives a finer resolution for that range. Adapters thread directly onto the test ports on the transmission or engine block. The only common issue is selecting the wrong adapter for a specific port thread, so confirm the fit before pressurising the system.

Dual-Gauge Range Decides Suitability

The single specification that determines whether this is the right part is the small gauge upper limit of 50 PSI (3.5 BAR). If the engine or transmission you are testing can exceed that pressure, the small gauge cannot be used and you must rely on the large gauge alone. Buyers who need accurate low-pressure resolution on engines staying within 50 PSI will benefit; those testing higher-pressure systems will not gain the extra precision the second gauge provides.

Questions about this item

How do I confirm the large gauge is reading correctly after connecting it to the transmission test port?

The large gauge covers all applications and includes a hang-up hook; verify the needle moves smoothly through the full scale when the engine is running and pressure builds.

Which adapters and fittings are included in the case versus what must be sourced separately?

The kit supplies adapters for most domestic and imported cars and light trucks including late models; the case has extra room for additional adapters you may need for specific vehicles.

When should I use the 50 PSI small gauge instead of the large gauge for engine oil pressure tests?

Use the small gauge when maximum engine oil pressure does not exceed 50 PSI (3.5 BAR) for a more accurate reading; the large gauge handles all other transmission and engine checks.
