I told him about our local Rural King but it sounds like he would rather pay shipping

As long as the chosen fluid eliminates friction, you’re good to go.

We use ATI 20w type F. Works good for us.

Curious on the negative on this one. So I was instructed to use a mineral F in my race 727 and ended up picking this stuff. Used it last season, no issues but being first year out with the car I only got about 25 passes in. But no shift problems and no heat issues. I have a gage on the trans, thought it didn't work until one night I went a few rounds and it registered on the gage but never over 160.


In my street car I use the ATI 20w previosuly mentioned as well. This has been one of the things that has drove me crazy as of late since the stuff that was orignally spec'ed for these is no longer available.

I buy it as cart filler from Summit...If I need to get over the free shipping threshold, Type F, spark plugs ,etc...

I recently switched to the ATI Super F 20W - great stuff! - its a full synthetic

FWIW I ran the ATI fluid prior to switching to Transynd in my Top Sportsman car

I run type F in 3 of my cars once they were new build transmissions. Still have Mercon in the others.

Not really a negative, more like a don't waste your money on the B&M. It is simply mineral type F with blue dye for a lot more money. I am sure it works as well as any other type F. Type F has been the go-to for decades until the synthetics showed up.

I have some quarts B&M Trick shift fluid will sell for a reasonable price.

I'm interested in the Transynd, stuff, Performance plus has their own version of this. Thinking I should do this on the new transmission in my truck, I'll run it by the torque converter manufacturer since
I have to send my converter back for some alterations.

Safety kleen has branches everywhere.

thanks all.
a couple of days ago, i ordered 24 quarts from rock auto.
with tax and shipping, along with the 5% discount coupon, it came out to $4.41 per quart.

Wow !! I should have checked on here first ! I clearly got ripped off by Advance at $9.79 a quart !!! I thought about trying ATI or another type fluid but my 904 has been in my mid 11 second Dart for 7 years now using type F without a problem . My trans builder built me a complete race ready spare 904 a few years ago , I haven't needed it ! So either the type F works well or I have a really good trans builder... I do !

Which Brand fluid did you decide??

If your not running a trans brake. If you have a reasonably sized cooler. If your trans was assembled with correct clearance. Then any fluid will work.

and to think I had a little bit of a tough time selling 30-some cases of type F, from back in the day when oil cans took pop in spouts to open the cans.... that I got at an auction about a year ago......... a collector guy bought all I had, came to Illinois from Lincoln NE to haul it out his way....
bought 3 pallets of various oils, to get about 2 rows of what was on 1 pallet.... ATF type 3... (yeah I know not +4, but Im sick of paying $8.50-11.00 a freaking quart for it.... ) every time I change a trans it's over $100 JUST FOR FLUID.
and ended up all of what I thought I was getting "disappeared" between the time teh auction was listed and the time I bid on it.... I ended up with 1 case of what I wanted... but a dozen cases of "stuff I can use".... still came out alright.
But yes I started out with 38 cases (of 12, not todays wimpy cases of 6) of Type F.

Doug, what brand would you recommend for a tranny that has a break/race clutches/aluminum drums that Rock auto sells?

I currently run JR1 synthetic. But in the past I’ve run Walmart Dexron with zero issues.

I had an issue with a flaired out bolt hole for the pump on my powerglide case several years ago. It was bleeding through and engaging my servo and wiping out my band. I was running Walmart brand Dextron 3 at the time because it was so easy to get and boy did the smell of it give me trouble. It has a smell to it like burnt clutches and made trouble shooting it hard. That’s the main reason I went back to type F.
