I have three vids. I just ran this about 8 miles, so it's completely warmed up, and after I shut it off for a few mins and turned it back on, you couldn't hear it. Listen to these vids, they were taken over a span of about three minutes until you could really start to hear it again. Ignore the fact you can't hear anything, just know that whenever the camera is in the engine compartment, it's being held directly above the vacuum line into the vac modulator.



In a way, it's a bittersweet moment. This means I can do an L67 swap because that's what I told myself I would do if either component were to fail. The negative part, however, is school just started back up and I'm not in a financial position to be able to afford an L67 + 4t65e combo.
Anyone have a cheap L67 + tranny combo they'd like to sell me?
Should I back off the vac modulator a bit? Could I have destroyed the fluid pump with that?
P.S. I just remembered this. I was on the highway today doing about 85 doing a quick pass to get around a truck before an exit ramp and 3>4 shift under 50-75% throttle took like an entire two seconds to complete, it felt like the clutches weren't grabbing. I guess I just solved my own prob, eh? Fluid Pump ie another (this will be my 4th or 5th salvage) trans?
