[Mr. Fixit]

Can someone please advise the total fluid capcaity of a TH-400 after a complete rebuild with a new TC. I have a plastic aftermarket dip stick and dont trust the level. I have a total of 9 quarts in now.

Thanks..

It depends on your torque conv. and trans pan (from 8-12qts) but 9 is for a bone stock tranny I'm pretty sure

Thanks for the info, I appreciate it..

Your welcome! And if I'm not mistaken,the next time you have the pan off of your trans. , you can double check your dipstick by marking a line on your dipstick even with the bottom of the trans. where the pan bolts to it...(make sure to leave the dipstick in the dipstick tube)

with a OEM converter and stock pan and cooling, 11 1/2-12. with deep pan and aux. cooler, up to around 13 1/2 total. (can be more with the aftermarket billet pans that are available now days)
smaller high stall converters (under 12") will take less fluid anywhere from 2-3 qts.

Thanks to all who replied. I have it filled correctly and apparently have another issue (manual shifting) unrelated to the fluid.

Jakeshoe recommended checking the line pressure, but I am not sure how to do that yet.

There's an 1/8" Pipe Plug on the Driver side a few inches above the Pan rail, about middle of Pan. You'll need a Gauge with at least 0-200psi. range.

("Brakes Applied"):---------- Normal Psi.
Neutral @1000rpm-------- = 55-70psi.
Drive @Idle speed-------- = 60-85psi.
Drive- @1000rpm--------- = 60-90psi.
Drive-2 @1000rpm-------- = 135-160psi.
Reverse @1000rpm-------- = 95-150psi.
Drive @1000rpm,
w/Downshift Solenoid On-- = 90-110psi.

This is great, thanks for the info. Where are the psi ratings from? Is it in a manual that I should obtain?
