I pull 20" off the booster line..I get only about 12" at the 4-way connector to the check valve (door locks). This is ok, as it's still enough to shift the car. HOwever, when my check valve is plugged in, i only get about 5"! I pumped vacuum and it held at about 10"....i locked/unlocked the car and the vacuum dropped a bit then slowly came up. I've tested each vacuum line on the car floor, front/back, driver/passenger, trunk lock. They all hold vacuum.

I'm just wondering that since my 3/2 valve (going to the tranny) was leaking, maybe this extra demand is lowering the overall vacuum? That doesn't make sense, since that check valve is one-way, right?

After pumping up the reservoir line manually, the locks are now operating. However, i'm not sure the car will shift....that's next test..So maybe the resevoir needed to be completely recharged to keep the whole vacuum system at proper vacuum when hooked up??

Hey, that totally seemed to have worked (pumping up vacuum at the 4-way connector). Once the reservoir was back up, the locks all work perfect, the car shifts properly and shuts down.

*Update

Reservoir went down overnight. I got enough vacuum to work the locks while running car for a bit, however not enough to shift properly. So, it would seem the 3/2 valve leak is still the issue. Getting a new one shortly.
