Sheepdip gets first choice.

I have the following three used vacuum switches available. These lock the torque converter clutch based on manifold vacuum. Each switch includes the original connector and some of the original wire. The contacts were a bit corroded, so I cleaned them up. I tested them all with a vacuum pump and a multimeter, and they all function properly.

15599002 on 4.5/off 2 1985-86 Van 4.3L, 5.0L, 5.7L - SOLD
14032087 on 4.5/off 2 1985-86 Truck 4.3L, 5.0L, 5.7L - SOLD
14014519 on 7/off 3 1985-86 Truck 5.0L - SOLD

$30 shipped, each.

I also have one vacuum delay valve. This is necessary to prevent the vacuum switch from locking and unlocking the TCC too quickly. This is a new old stock aftermarket delay valve, not the original GM part, but it functions the same way.

Borg-Warner EC301 - SOLD

$30 shipped.

Here's a video that shows how the delay valve works.

I can combine shipping if multiple items are wanted.
