Default Trans brake solenoid question.

Is it normal for the outer plunger deal to move independently from the rod in the center? I never paid much attention in the past. Recently my Glide acts like it’s slightly stuck in reverse. Trans brake holds the car fine, but doesn’t want to release it. After I release the button it takes like 3+ seconds to release the brake. And it doesn’t release smoothly. Seems to engage reverse fine and the car backs up fine. But when I drop in to low gear the car hangs and doesn’t want to move. If I accelerate a bit the car creeps forward slowly. It acts like a hung brake caliper. Then once moving it seems fine and no longer drags.

I have confirmed all the detents on the shifter are spot on.

This solenoid has no return spring and relies on fluid pressure. Any ideas?



I see no burrs on the valve shaft. Seems to move freely.

Is the return spring that goes around the plunger still fairly stiff? That's the only thing I can thing of that would cause the issue you are having. Maybe if it is weak...it isn't fully releasing.

This style uses fluid pressure to return the brake valve, no spring. I was told the shaft/valve shud be pinned to the plunger. mines broken. ordered a new one. hope it fixes it.

Won't be here till monday and I have a race this weekend. I welded the bastard back together where the pin and plunger came apart! Then put some JB weld on the wires where they were frayed. Bench tested fine and it's going in the trash when the new one arrives so why the hell not?
