420A Engine & transmission vacuum leak.

[96WhiteEclipse]

So my car recently decided to take a massive shit. Everything was going fine but then SIMULTANEOUSLY my break pedal firmed up (have had ongoing issues with soft pedal) I had shift issues and idle issues. I’m going to guess it’s a vacuum leak but the car won’t shift until around 5000 rpm. It’s a 2g 420A with the Chrysler A605 (41te) transmission. I’ve looked everywhere I see no vacuum lines disconnected but I don’t know which lines to test or what to do. Is this just a major hidden vacuum leak? Is there a valve that could be clogged?

Check your large vacuum hose going to your brake booster on both ends and also for tears.
