Wade, the type of fluid required is determined by the type of friction materials used. Modern friction materials are compatible with synthetic fluids. Type F fluid will normally still give a more "positive" shift.

Wade use the type F as you should know PG's love temp! If your not going to the water box with 150 degrees of temp in the trans your leaving ET back @ the trailer! p.s. it's the only thing I don't use synthetic in.

Try the Royal Purple. I had a buddy that helped with some of the development of it & I tested some in P/G's. The way I understand it they have reduced the friction modifyers to make better clutch lock up. I found it made all the roller bearings I was installing in P/G's last longer than Type "F". Never saw any clutch or steel wear or burning, either.

amsoil also has a very good product called supershift,it also has a very low amount of friction
modifiers and makes things run cooler.

I have been using the Mobil 1 Syn Trans fluid for about 15 years. I have a friend with Mobil Oils Marketing and he gave me some when it came out sometime in the 1990's. It worked so well I have used it every since. No need to heat it up. It works the same for consistancy cold as hot. Just drive it to the staging lanes and when the motor is warm the tranny will be OK. After hot lapping it in eleminations on a hot day I have yet to see the tranny temp to go over 160 to 170. I do use a cooler and it seems to take care of it. In my powerglide I used the same band for 8 or 9 seasons putting 150 to 200 passes a year on the trans with a freshening each season. There is virtually no wear on clutches each year. It is the only tranny fluid I use for racing. I also use the Mobil 1 gear oil in the rear end and Mobil 1 oils in the engine. All work well for me.
