You chose correctly up
I've always used it since 1974 per directions from the old Mopar drag race seminars put on by the factory Mopar drag race engineers up scope

I run Type F, but use Redline's synthetic version. I believe ATI's synthetic ATF is also Type F, FWIW.

Street use with the additional heat & slippage from a high stall converter rules out standard (non-synthetic) ATF for me. I also use an accessory trans cooler. But that's my approach and others may not agree.

A lot of street use w/ a 5k stall converter here w/ conventional (non-synthetic) Type F and no issues. Been doing that since 2003 or so.

Synthetic is a "peace of mind" thing for me. Years ago I recall seeing some tests showing at what temperature conventional ATF started to break down vs synthetic, and that persuaded me that I'd be better off w/ synthetic.

BradH...I don't doubt the synthetic is better w/ heat. Just throwing it out there that the normal stuff works fine.

If I can’t hurt Dextron 3 or type F I think you are fine. A powerglide and transbrake really test how good your fluid is. Zero issues

Is that before or after you drove 100+ miles one way to the track every weekend for a month?

All I'm pointing out is that I don't think we're all looking at it from the same perspective. The OP said a street/strip car w/ a high-stall converter, which fits with my experiences.

As I said above, not everyone is going to take the same approach that I do (and that applies to a LOT of things laugh2 ), so I don't know why people feel the need to reply in a manner that insinuates that I'm "wrong" and they're "right".

People -- obviously -- should run whatever they want. I'm glad others have good results doing different things than I do, since I know how much it can cost to make bad choices that hurt reliability & performance. However, the guy asked for an opinion and I provided mine because his application sounds very similar to mine.

Advice From Rossler's site - I have aked him many times same answer for TF's

Synthetics are Acceptable but Not Required.



900 HP OR LESS - Recommended Fluids



Dexron3/Mercon



Racing Fluid (B & M or TCI)



Ford- Type F



50/50 Mix of Dexron 3/Mercon and Ford – Type F



900 -1,500HP - Recommended Fluids



Racing Fluid (B & M or TCI)



Ford- Type F



50/50 Mix of Dexron 3/Mercon and Ford – Type F



1,500HP and up - Recommended Fluids



Specialty Racing Fluid



Racing Fluid (B&M or TCI)

Hydraulic Oil (10W-20 or 30 Weight)



10-20 or 30 weight synthetic fluid acceptable on all level horsepower the heavier weight fluid the better lubrication to gears and components you must use a slightly higher viscosity fluid to equal lubrication value of conventional non synthetic fluid. The less horsepower you have the lighter viscosity fluid you can use as horsepower increases so should the viscosity of the fluid. Although some turbo powered cars and cars equipped with lock up torque converters need the thinner fluid for spooling and stall speed adjustment purposes. Unfortunately this is a necessary evil that can shorten the life of the transmission planetary gears.

One of the aircraft mags I use to get had a article about synthetic oils that said standard petroleum based oil molicules would start to break down at 325F and that the synthetic based oil molicules, back then, mid 1990s, would start to break down around 525+ F shruggy
I do remember reading about the dye in all automatic trans fluids back in the early to mid 1960 that stated that the dye would start to change colors at 275F and go from red to brown and become black at or above 325f shruggy
