722.4 Surprise & Vacuum question
Kind of really awesome, but the torque converter on the 722.4 and 722.6 cam be DIY drained. I have never seen this before. Just turn the harmonic balancer 27mm bolt until a hex bolt appears in the eye of the bell housing.
That's the drain bolt! It looks just like the drain bolt on the transmission pan itself.
The question I had had to do with vacuum actuated 722.4: I know there is a modulator right where the vacuum line attaches to the transmission. Is there a procedure to tune this setting? Any guidelines?

I didn't realize the converter could be drained until I removed the left downpipe/cat assembly to reveal the little rubber cover that goes into the bell housing. No way to get at it on the C43 unless that assembly is removed!
