Your best bet is to get in touch with a tranny guy (shop), see what he says and work out a deal for him to disassemble and inspect. He will probably give you a certain diagnosis for around a$100. It sounds like you want to keep this on a tight budget. So you're gonna have to do the dirty work. Th400s are plentiful and finding a good used one or a reasonable rebuilt one is easy and economic. I found a good used 700r4 and swapped my buddys old granny 4 speed with TV cable and shortened driveshaft and everything to get it running for less than $700 a couple years ago. No big deal. There are tons of articles and info here to get you confident-ally started. Drop the darn thing and find out whats going on.

I believe it is (or was) leaking from around the modulator. I replaced the modulator too. I do want to bring it to a tranny guy and try to salvage this one if possible. I know it is possible to get another for relatively cheap. Maybe thats a better way to go? Are all TH400's the same or do I need to find a specific one for chevy / my engine?
Thanks for the reply!
