Help with 84' Chevy 1500 Trannie

I have a 1984 Chevy 4WD, 1500. Auto transmission. I've never had any problems with the truck except for normal maintenance.
When I pulled from the house today the transmission when it started
to shift felt like it was slipping. After about 4 miles when going up a hill I heard a 'pop' underneath and then lost power.
It had no forward but I could go in reverse.
I looked at the linkage and all appears to be working alright.
That's when I noticed a leakage coming from the left side of the bell housing.
A check of the fluid indicated that it was low and I put more fluid in (level ground).
It still would not engage in forward..it would engage in reverse.
Question: Does anybody know the type of transmission that is used on this truck in case I have to get another one?
Could it be just the torque convertor?
Is there anything else I can do to check it out except for dropping the pan on the trannie? (I know it's an old truck but I've had it a long time and I like it and take care of it.)
Thanks for any input or advice.
Josh

If it is a overdrive tranny its a 700r4. 84 may or may not be a 28 spline input wit aux. valve body and a wire going to passenger side servo. If it is you are double screwed. Dont bother with a rebuild. Of course if it has been in there since 84 its probably not a 28 spline 700R4, woulda died long ago. Regardless of what tranny you got sounds bad, take it to a shop. Make sure you ask them if its a 28 spline, if it is find a 30 spline. 88 and up K case are the best.
