We've been getting some good miles in this summer, in fact we've put almost 1000 miles on the car since April. Since the Corsa seems to be pretty happy again, I decided to work on the Monza today. I've had all the parts for a while, and finally got tired enough of the leaking PG that I ripped into it. Pan drained and dropped:
Next up was pulling the TV lever out. It's not hard, a bit tricky maybe, but came out fine. The o-ring has seen better days, a little hard to see in the picture but basically the same diameter as the shaft. I think this was the biggest leak:
I reinstalled the TV lever and pulled the shift cable. I had seen some RTV from the outside, but didn't expect all of this as a "seal" - new o-ring on the left:
After putting the cable back in (shifter in D, TV lever rotated CCW, all lined up perfectly), I moved on to the manual valve adjustment. I borrowed the tool from the Philadelphia Corvair Club, made it super easy. Not sure why it was so far out of adjustment, maybe from the previous "seal", but I had to move it a bit to be back in spec:
I pulled the filter/screen down as well and found that it didn't have an o-ring. Cleaned it up and installed a new o-ring and put the pan back on with a new gasket. Filled it back up with some more fresh ATF (between this pan drop and the one a few months ago I've drained out about 6 quarts and refilled with fresh).
Fired it up and a quick leak test looked good, so took a road test. It shifts so much better! Really nice upshift and downshift, no need to put it into L before D anymore, and no more flare between shifts. Fluid level was good when I got back, but it did leave a drip on the floor (looks like it came from the pan gasket, nothing wet near the shift cable or TV lever). I went around the bolts again, but still trying to be careful not to over tighten. I'll let it sit a few hours and see how it goes.
