AW4 Solenoid Check

[tweedles]

I know that the way to test the solenoids on the AW4 is to test their resistance. For this, you have to pull the pan, disconnect the leads, and put an ohmmeter to it. Is there a way to test the solenoids in the AX4 wihtout pulling the transmission pan (ie. from the solenoid wires coming out of the TCU wiring harness). This is on a 1989 XJ, 4.0-AW4-242.

Yes you can check them without dropping the pan, just find out which wires go to the solenoids and measure the resistance between the wire and ground(metal case of the aw4) when the connector is unplugged from the TCU. The ones I've tested read around 13 ohms.

I tested them from the TCU leads and had no resistance. Does one solenoid failing cause a cascading effect which takes them all out? Also, anyone know the price on the solenoids?

if you have a bad soliniod ground on most transmisions and transaxles iv taken apart the soliniods share a Command ground wire
