MegaShift™ 4L60E Stimulator
We will offer a stimulator (aka. "stim") for the 4L60E (for use with the GPIO, but it will work with any transmission controller for the 4L60E, as well as many other transmissions).
It has:
- all the connections for the 4L60E except power (which comes into the board from pin E, but which must be supplied from the harness) - the pins to the transmission connector are labeled on the board to match the connector,
- LEDs to indicate the status of the PC, TCC, 3/2 sol, and Sol A & B with a silkscreened table to indicate the appropriate status in each gear (with the resistors accessible for scope use),
- LEDs (D1-D4) to indicate the gear the controller thinks it should be in,
- a rotary switch ($4.88 @ www.digikey.com) to select the manual shift lever position gear (the other pole is brought out on a 0.100" header)
- three #10 screw holes for mounting or stands, as well as grounding a scope probe,
- a pot for temperature feedback.
The board is 2.5" x 4". Users can either plug their ampseal pigtail into this, or use a 4L60E internal connector to test their entire harness (the pigtails are common - transmission shops frequently replace them since they have the TCC solenoid as an integral piece - new they are about $40). The price will be very reasonable - the most expensive component on the PCB is the rotary switch.
