Okay at highway speeds, the reverse lockout solenoid is energized meaning you can get it into revers gate, and grind gears. Not good.

I am under it now and when the ignition is turned on, the RLS is energized like it should be, and its unlocked. And if I disconnect the connector, the solenoid locks as it should. Also passes the bench test.

Now this solenoid is a replacement used unit since I broke the connector housing on the original one, putting the engine back in. But I would ASSume that all of these RLS are the same for all T56. Maybe not. But the damn thing again, passes the bench test and works fine.

Any ideas why the PCM is energizing the RLS when it should not?

Thanks

 

If the connector plug is white, it's a CAGS solenoid.
If the pin is retracted off, and extended when voltage applied, it's a CAGS solenoid.

The smaller, new version of the RLOS with black connector is reverse compatible.

 

Is this not the reverse lockout solenoid?

Again this thing is energized all of the time. It should only be energized when speed has exceeded 3MP. Any ideas why this might be?

 

Perhaps the wiring harness near the passenger side exhaust header is grounding out? I had a similar issue recently where the harness jacket melted away exposing a conductor, that when grounded, impacted the reverse lockout solenoid.

 

Simply check wiring, check it is the correct plug etc.

And when was the last time it worked correctly ? What work has been done or what has changed from that time ?
