30L Ultrasonic Parts Cleaner for Transmission Valve Bodies

A 30 liter (7.9 gallon) heated ultrasonic tank sized for transmission work. The stainless tank measures 19.7 x 11.8 x 7.9 inches, which is enough to lay a full 4L60E, 4L80E, 6L80, 5R110W or 6R80 valve body flat in the basket instead of cutting it into pieces the way a 6L or 10L bench unit forces you to. Ten transducers put out 600 watts at 40 kHz, and a separate 600 watt heater brings the bath up to anywhere from 68 to 176 degrees F.

The job it does on the bench: varnish, clutch material and aluminum fines wash out of the valve bores, accumulator bores and the feed holes in the separator plate, including the passages a spray gun and a rifle brush never reach. Shift solenoids, pressure control solenoids, checkball seats, pump halves, filters screens, TCC regulator valves and small castings all come out clean without you scrubbing bores and rounding the edges of a valve land. That matters, because a bore scratched during hand cleaning is the same bore that causes the pressure complaint you were trying to fix.

Typical use is water with a few ounces of alkaline parts wash or simple degreaser, heated to roughly 140 F, and 10 to 20 minutes of run time on a valve body. Degas a fresh bath by running the tank empty for 10 to 15 minutes first, and keep parts up off the tank floor on the included 304 stainless basket so the transducers are not loaded directly. A built in drain valve on the side empties the tank without lifting a 30 liter bath, and the digital panel sets time in 1 to 30 minute increments and temperature by degree. Unit weighs 31.3 lb and runs on standard 110V.

Do not run anodized, painted or plated parts you want to keep cosmetic; the cavitation will lift finish. Aluminum transmission castings, steel valves and solenoid bodies are fine.
