My PG had a leak from the shift cable, it would leak pretty badly with the car sat for more than a week. I fixed it with the recommended silicone tape and it has not leaked in a little over a year.

The factory converter is a little too tight in my opinion which drags the idle down. I have a high stall converter I've just been too lazy to install it.

I'm looking for opinions (from automatic Corvair owners) about your powerglide.

P1) How many PG owners have leaks due to weak/old torque converter seal?
P2) After a good drive, how many days go by before it starts dripping again?
P3) Did replacing the Torque Converter & gaskets fix your PG leaks?
P4) Do any club members have experience with a high stall TC?

Clarks recommends a High Stall TC (over stock) saying it will prevent stalls or engine drag at stop lights. My Dune Buggy is so light mine doesn't stall, but it does drag my engine when I brake and chirp the tires everytime I shift it into gear. I think this may be a good upgrade for me but would like to hear other opinions.

BTW - I need to go for a drive every 4 days now, to temporarily stop my PG leaks. This has gradually gotten shorter over the summer and snow is coming soon.

Thanks, I appreciate your PG experiences.
