What's the general consensus on the correct transmission fluid for a cast iron Torqueflite? I've had people tell me ever transmission fluid on the market. I know type A is what was originally used. The only type A still available seems to be the cheap golden star brand found at the gas station. Any experience with different types and brands appreciated.

The original spec Type A fluid contained sperm whale oil because of its exceptional lubricity and heat stability. Sperm oil was outlawed in the early seventies so its use ended.
