C-4 help I am the only one in my area running a ford and I keep burning up the
low gear clutches I have a Perf. Auto valve

Do you run a cooler? That thing has got to be running hot in low gear. Years ago I ran one in drive with a hogs head and it would burn up without a cooler. Thats probably why it puts oil out the dipstick.

What clutches are burning up? C-4s do not have 'low gear clutches' they have a forward clutch pack and a low\reverse band?

I have a cooler just can't figure out why it keeps burning up the forward clutches and blowing the fluid out.

What kind of torque converter did you use?
Does the car have a vibration?

The only reason that the forward clutches would burn up is probably a lack of or drop in line pressure, no doubt due to a bad\wornout front pump or a problem in the valve body concerning the pressure regulator valve assembly, either the above mentioned or just plain old poor workmanship on the clutch pack at the time of rebuilding, such as, wrong pack clearance, dirty assembly, worn out bushings and ring lands, end play issues, etc.
I have raced and rebuilt many C-4s and they are a real strong unit when built properly....not known for unreliability.
I built and raced direct drive C-4 with homemade torq conv eliminators way back in 1989.
