727 transmission questions

[TheCouzin]

Forgive my amature questions. I grew up in the wrong era.

Being a mechanic for my career in today's day and age. I didn't have much experience playing with the cool old stuff like there was back in the day. I bought this car in June and am taking some stuff apart to reseal and make some slight modifications to.

Yesterday I removed the hooker headers to dent them in a few places to stop.them from knocking on the torsion bars. Upon doing so I had to remove the transmission dip stick/tube. Transmission fluid came pouring out the tube hole. I was semi prepared to catch some but not a few liters.

So my question.

The transmission dipstick doesn't protrude past the tube. Is this normal on these old things?

As you can see in the photo this is not the stock trans pan. How does the fluid level work in this set up? Is it still get to temp and pull the stick and adjust accordingly? Does the transmission fluid fill up past the pan and seal?

Again forgive me with my knowledge of the old stuff. Learning as I go with it and having fun. Im upset I only have experience working on new stuff. And yes its dirty under there as im tearing stuff apart haha.
Thanks for your time.

Your dipstick placement in relation to the tube sounds normal for a 727 and you will lose fluid from the trans when the tube is removed. Check the fluid level at idle with the trans in neutral.
Because of the increased pan depth your trans may have been fitted with a filter extension, either way, fill to the correct mark on the dipstick in neutral and you should be good to go.

Deep pan probably an extra 2 quarts.

Depth of the pan has nothing to do with it. What you have is converter drain back which is normal. When the car sits the converter slowly drains back raising the level. The longer it sits the more it will drain back until it finds a happy level.

Awesome! Thanks for the replies all! Yes will check fluid properly when I get it all back together for spring/summer.

No. I did not mean that the pan has something to do with it, just meant to say that deep pan probably holds 2 more quarts of ATF. Dipstick level would be the same.

Yeah, the old stuff to you is like the Model 'A' Fords were to me back in the late 60's and early 70's. I couldn't understand how my dad liked the old A's lol. These days I like them now. Go figure....
