CTA Tools 2001 - Automatic Transmission & Engine Oil Pressure Tester
Choose the CTA 2001 if you prefer a single gauge with a scale from 0 to 300 psi and a six-foot hose for engine-oil or transmission-pressure checks. Match the supplied SAE or metric adapter to the test port and follow the vehicle’s specified pressure procedure.4
For a simple engine oil pressure check
The CTA 2001 uses one gauge with a 0 to 300 psi scale for engine-oil and transmission-pressure testing. Check that scale and the supplied connection against the engine’s pressure specification and test procedure.4
For testing transmission pressure as well as engine oil
OTC declares this kit for both transmission and engine work. Select the gauge and adapter specified for the circuit you are testing; a connection that fits one port does not establish fit for another.1
