Stay away from type F. If you can spend the money, synthetic is always better.

Your top synthetics are Amsoil and Redline. Nonsynthetics, the best are Mobil Dexron 3, and AC delco. This information is based on results from teardowns on hundreds of transmissions (I have done myself) and from talking to hundreds of other transmission builders, and getting feedback from them on what works. Always use the OEM style filter. It is a Sealed Power filter, now known as Filtran. This is a Zero Leak filter, and the only one that protects the front pump from fine particles of metal.
Hope This Helps!!!
