Reads automatic transmission line pressure from 0 to 426 PSI on a backlit digital screen, with copper adapters and a hose to fit most automatics.
Handheld digital line-pressure tester (AUTOOL PT650) for automatic transmissions. It reads 0 to 30 bar (0 to 426.6 PSI) at 0.5% full-scale accuracy with 0.01 bar resolution on a 2.8-inch backlit LCD, and switches between PSI, bar, and kg/cm2 so it matches whatever the factory service data lists.
On the job you thread the correct adapter into the transmission's line-pressure test port, connect the oil-resistant hose, and read line pressure at idle and under load. The screen holds current, max, min, and differential values, and the buttons let you zero, lock, and clear a reading, so you can watch commanded pressure rise and fall as the trans shifts and compare it against spec without a helper.
Use it to pin down a weak or worn pump, a sticking pressure regulator or boost valve, a clogged filter, or slipping clutch packs by confirming whether line pressure actually climbs the way it should. The kit ships with metric, NPT, and quick-connect riveted-copper adapters plus the hose, covering most domestic and import automatics, and a 40 bar overload rating protects the sensor from pressure spikes.
