I got a leak, my mechanic says its a little rubber valve on top of my auto park control valve thats is dripping. The piston area.
He looked online for it and said he found one for a butt load of money.
Blew me away because GM stopped making them in 2002.
ANYBODY out there that has this part, where I can find this part or try to stop the leak? My mechanic said I can add a power steering leak seal and in hopes that seals it, but other than that I am screwed. If the photos don't work here I am more than happy to email you.

I would give these guys a call, they might be able to point you in the right direction if they don't have one.

Maybe an RV salvage yard.

Bendix part number 106479, Control Valve Assembly crosses to Assembly, Valve Control,Workhorse TW-12 15654261. Here's one for $266.66 which is way cheaper than the $900 they want for the original GM part.

You have the GM J71 AAPB and the expert about them is Roger Haag who offers free advice on his website: AutoPark parking brake system help, troubleshooting, and repair

Go there, and contact Roger if you don't find the answer you are seeking.

found it for $225 at finditparts.com . part# 106479 by bendix if you all ever need to find it for yourselves. Not sure why they are $225 versus $800-$900 at other websites.
