Is that before or after you drove 100+ miles one way to the track every weekend for a month?
I had a 727 in my car 16 years with the same cheap type F in it, it also had 5 drag weeks on it. No problems, i only pulled the trans to switch to a 904. On Drag week 18 I got the trans hot in the mountains(the new 904), noticed way more converter slip than normal and the cooler couldn't be touched by hand. I let it cool off for 30 minutes then back to the road. I expected to need to change the fluid the next morning but it was as clear and clean as when I put it in.

The more synthetic fluids out there the longer the cleanups are. You wouldn’t believe in this day an age how many guys still use hose clamps on their engine and transmission lines.

... You wouldn’t believe in this day an age how many guys still use hose clamps on their... transmission lines. Note to self: Upgrade trans lines to replace hose clamps on the four (4) high-pressure connections for the two (2) high-pressure trans-spec rubber lines between the hard lines and the trans cooler. EDIT: The hard line & trans connections are flared and barbed, respectively, but I definitely want to update this stuff.

You wouldn’t believe in this day an age how many guys still use hose clamps on their engine and transmission lines. ...or cheap, rubber gas line because it's a lot less money. Everything on a race car should be a threaded connection except for maybe radiator hoses. The Rossler recommendations seem fine. I've tried high end synth street ATF and didn't like how the clutches looked. Heat streaks from slipping on apply. Amsoil makes a racing synth Type F which I understand is developed from oil used in large powershift units in large equipment. "B&M & TCI fluids" and also ATI fluid is rumored to be repackaged powershift/hydraulic equipment oil, so there's that. Again, we used Valvoline/NAPA Type FA, changed it every 50 runs or so and had no fluid issues. Pro tree, 6000 on the mat, no 2 step, every pass.
If the results don't match the theory, change the theory.

I think I have around 100.00 in my transmission lines that were made at a local hydraulic shop. Being my powerglide runs hot I told him the temps and he used lines to handle it. My fuel fitting are also AN style fittings as are my radiator hoses. Sure makes things safe and nice to work on.

EDIT: The hard line & trans connections are flared and barbed, respectively, but I definitely want to update this stuff. Just use AN braided line. I have -6 braided steel lines on both my cars. 1/8" NPT to 6An fittings for the trans and radiator if I recall correctly. Normal braided line works great...been on my car for probably 14 years now. If you feel uneasy about it, use the more expensive braided line w/ the Teflon (?) liner like you'd use on high pressure nitrous lines.
