Well, when we installed my tranny, I believe it took around 13-15 quarts to fill her up. 2 in the conv., and the rest down the fill tube. I dont know about an overfill hole.

Did you install an aftermarket t/c? Cause some have drain plugs on them(for better fluid changes), and maybe it wasnt tight, maybe missing? I cant even remember if mine had a drain plug, it has been a while since I have been under there looking at it, what a good tranny!!

drain plug in and tight! Front seal bad, damage?! I'm gonna hate pulling that trans again!

 

I am now stumped?:shrug:

The best advice I could give you is talk to Dave @ Goerend Bros., or Mike at ATS. When I was doing my tranny shopping, both of these guys had lots of info for me and didnt hesitate to answer my queshtions. I am sure there are others DTT, Suncoast, ETC., these are just the ones that I know of.

 

you read my mind!! Just got done talking with Dave! There is a vent behind the TC if you put to much in it will come out there! This TC is awsome and Dave is just great for help! I would recommend Goerend to anybody. This truck drives like a whole new beast! Got it up to 100 wow does it shift awsome! And now we know!

 

You say that you put the 15QTs in but was that all at one time with out starting the engine? If you didn't put in 4 qts and the start the engine before adding the other 11 it probably is running out the case top vent. Pan holds only about 1/3rd and torq. about 2/3rds on most tranys.
