Street/Strip car running TH350, what tranny fluid would be best?

[RickSBC400]

Hello,

I have a street strip setup th 350 with a 3,500 stall converter and a full manual valve body and a deeper pan so it holds more fluid, i think.

I am contemplating changing my fluid for the first time that I can recall, it has some miles and some drag passes on it.

What fluid would you recommend for a setup such as this? I am all for strong shifts and protection and don't need to spare any expense when it comes to buying new fluid. Oh and it performs fine now, so no issues just figure you should change the fluid, or correct me if i'm wrong??

Here's a recent pic of the car at Bandimere in Morrison, Co.

Thanks,
Rick

I have always had good luck with Amsoil ATF, there is also Redline D4

Atf type f is usually used in drag racing for these transmissions because of the fast engagement. But whatever you're using in it seems to work fine so maybe keep using it.

HPL Blue or Blue CC

The soon to be gone Bandimere...sigh. Personally I would just use any off the shelf fluid and change it more often.

I use High Performance Lubricants Light Type F in my drag only TH350 with RMVB. They have it in various viscosity of light, medium, and heavy. It's very stable and lasts a long time. I like Type F in a TH350/400 as it firms up the shifts with more instant clutch engagement.

What does the builder recommend?

I run Dex/Merc in street/strip TH350 with full time max line pressure, The Intermediate Roller Clutch Race is the weakest link in this unit.....Even with a Hardened Race, I run a Intermediate Wave Plate & stay away from Type-F.

You can take a TH350 to it's physical limits with Dexron III & enough Line Pressure.

What does the builder recommend?

was built about 20 years ago and builder is long gone, no idea what he recommended back then!

TES-295…

Has viscosity of Dexron III, but is full synthetic…
