10L Heated Ultrasonic Parts Cleaner for 4L60E Valve Body

A 10 liter heated ultrasonic tank sized for the parts a transmission bench actually needs cleaned: a 4L60E or 4L80E valve body, a separator plate, a pump body, solenoid screens, accumulator pistons, and a basket full of checkballs and small valves. The tank measures 14.9 x 10.9 x 10.8 inches inside, which clears a full GM valve body casting laid flat instead of forcing you to break it down into sections.

Two knobs run it. One sets the ultrasonic timer from 1 to 30 minutes, the other sets the heater anywhere from 70 to 175 degrees F. The 240W transducer array does the cavitation work and a separate 300W heater brings the solution up to temperature, which matters because cold solution barely touches baked-on varnish. A typical valve body cycle is 15 to 20 minutes at roughly 140 degrees F in a diluted water-based parts solution, then a rinse and blow-dry with shop air before reassembly.

This is the fix for the failure mode that sends a rebuild back: varnish and clutch material left in the valve bores. Hand-cleaning with brake clean and a rag will not pull debris out of a blind bore or a checkball pocket, and leftover fiber is what sticks a TCC regulator or a boost valve and lands you a P1870 or a harsh 1-2. The tank is 304 stainless in the basin and basket with 201 stainless outside, and it has a drain valve on the side so you can dump used solution without lifting the unit. Basket included.
