I was under the search and read that valvoline tranny fluid was not good to run because it foams. What about B&m tranny fluid or maybe synthetic in the powerglide? Eddie

My tranny guy told me to run in my Glide the cheapest ATF that I can find and change it every 3 nights.

Walmart has some no-name ATF that I've been using for over a year now.

J.W. Performance says use type F fluid (they build Powerglides and components used in 2000 H.P. dragsters). They say it is a "sticker" fluid that clings better and allows less slippage of the clutch discs. I've used the type F fluid for 5 years in my Powerglide and it works good for me.

I recomend Dexron type. Type F tranny fluid does stick better than dexron BUT with a race Powerglide the clutch's should not be slipping at all and the extra grip of the type F just makes it harder to turn the clutches that are not engaged. (reverse and high or low) So it needlessly ***** horsepower.

Thats good advice change oil every 5-7 features filter every 20 features the oil will tell you when its time to rebuild it will start to look like pancake suryp, when it looks like used motor oil its too LATE!

I heard that standard tractor hydraulic fluid had more of the ingredients to keep the cultches from slipping than Type F does.

How about some more info on the two types of fluids!?!?
I was always told never mix the two and keep dextron dextron - type F type F.
Is type F thicker?

I guess I need to get a tranny fluid manufacturer on here to help us. Give me a few days and I will see if we can get some really good answers.

I have been running dexron for 4 years but had been wondering if type F would be better.I checked and the vicosity of dexron and type f are almost the same.Type f has a higher Viscosity index than dexron which is it's ability to resist break down.The tractor hyd jammin mentioned is a good bit heavier and has a lower VI.I would like to hear more about what the tranny builders are recomending for their products.

i use lubrication engineers "powerfluid" it's really not made for automatics but i run all season in a mod and fluid looks like new at end of year . valve type direct drive. but i don't slip it much . ie i try to keep the valve closed as much as possible and i use a winch to load the car.

Most of the racers I know around here are running Dextron in the glides and we change ours every few races. I have used type F in TH350's before. What I've always heard is that type F is more similar to B&M Trick Shift fluid. I'm hoping Jammin gets a good transmission guy to post because I'm curious if that theory holds true or not.

B&M used to recommend either Type F or their own Trick Shift. I put a shift kit in a Turbo 400 and topped it out with Type F (I did not drain the convertor) and drove the car for at least another 40,000 sometimes hard miles and never had bit of problem. I was told as a kid that you could mix Type F with Dextron in a GM tranny but you could not mix Dextron with Type F in a Ford tranny.

I hope this article will help clear the air on transmission fluid and give everyone a better understanding on fluids. We dyno all of our transmissions with dexron III fluid and have found out from drag racers that the newer Dexron fluid will actually help the transmission shift harder and it will run cooler. It use to be the opposite. Type F was the fluid of choice. We have our own type of fluid that is a Dexron III based fluid with moly additive and anti-foaming agents. It will actually bond better to the hard parts and lubricate better that basic fluid and will not breakdown as quickly as basic fluid does.

Talked to Bushore and he said to run regular dexronIII,nothing trick,and change fluid every 3 to 4 nites and filter every 10.I think he knows what he is doing so i follow directions! Just my 2 cents worth! Vasseau Racing 55
