TH350 Transmission Help!

WHAT'S Up Everyone!

Well, its been a while since I've been on here (been busy with work)... I finally have time and a little bit extra $ to work on my '85.

Heres the question/what I did....

My Transmission was leaking from the pan, so this weekend I went to O'Rileys and got the new gasket and a gallon of transmission fluid. I took off the pan and let it drain (Friday Night). I went to put on the new gasket and it happend to be the wrong one. So today I went back to the store with my transmission pan and got the correct gasket.

I put on the new gasket and put in about 3.5 quarts of the transmission fluid and let it settle in. I went to put it in drive and NOTHING!!

The truck drove before I changed that gasket.... (when I found out it was low on fluid all I did was add 2 Quarts of ATF, and by the next day it had leaked out)

Right now I am unable to check to see if there is enough fluid because the tip of the dip stick was broken inside the tube close to the pan.

So I guess my question would be:

How much fluid is actually needed in an TH350?

OR

Do I have bigger problems?....

Re: TH350 Transmission Help!

i would remove the the houseing bolt holding the tube
slide the tube out/up from under the truck
try and remove it to measure it
to hard to guess how much is in there......converter holds a lot
not enough it won't work,but to much is bad too

Re: TH350 Transmission Help!

Thanks for Responding Motornut,
I got it to work now...

Yesterday I stopped by a local salvage yard and picked up a dipstick and a coolant overflow cap for the truck. I checked the level and sure enough it was low... added another quart.

So looks like the amount of ATF needed is about 4.5 - 5 Quarts.

I was able to drive the truck around the block a few times so its all good now....
