<VV> Powerglide Transmission fluid

[akacubed at comcast.net]

Hello everyone,
         I am a new member to CORSA. I have a 65 monza with an automatic powerglide tranny. I was wondering if anyone can tell me a good type of transmission fluid to use. It is leaking some fluid which appears to be coming from the front pump cover seal. The manual refers to a type "A" fluid bearing an "AQ-ATF" mark. I cannot find anything like this at the auto part stores. Any suggestions would be greatly appreciated.
Thanks,
Abe
