c4 fluid capacity

[ashford]

i recently changed my torque converter and am hving a hard time determining how much fluid to put in it.

dipstic in pan tci streetfighter
10 inch tci 3000 stall torque converter
aftermarket dipstick

tci states that a c4 holds 5.5 qt and a 10 inch converter holds 3

i went out and bought a 10 qt jug of tractor fluid poured out 2 into a separate container(8 qt now in jug). i put some in the new torque converter, drained the tranny, installed torque converter and dumped the rest of jug in tranny.
when i get on it hard i get fluid out of the breather(i put a hose on it and mounted on the firewall) it did that once and never repeated with tci converter.

i know the dipstick is way off when i first got the tranny and a hughes converter when filled to the full mark it took forever to go into gear. so i put on pint in at a time till it went firmly into gear and added another quart, about 10 total on a 12 inch converter.


do you think maybee i have another problem pump pickup or something. im stumped it works fine over full but is a thin line between not spitting out and starving for oil

I've got a case fill C-4 and it holds about 9 qts with a deep sump aluminum pan.

my C-4 is a 164 tooth, big bellhousing style. When it had the stock convertorI put in 9.5 quarts to get it to the full mark. When I put in an aftermarket 11.4 inch TCI convertor, it only took 6 quarts to get to the full mark.

Did you know that you have to fill these things with the engine running for best results? Anytime filling a C4, I recommend putting in 5 quarts and running it through the gears. Add a quart at a time until it starts grabbing gears, then fill it to the full mark. Then you can turn the engine off or drive it around.

It shouldn't hurt anything to overfill it, you will just get tranny fluid shooting out.
