Repair

Hello, my name is Sam and I drive a 1996 Chevy
Tahoe.  One day I was driving home and noticed my
car was jerking. I opened the hood and noticed a
hose was leaking transmission fluid badly. I patched
up the leak and continued to drive home with no
transmission fluid. My truck wouldn’t go over 50
mph the entire ride home (15-20 miles away). I got
home and filled my truck with transmission fluid and
it worked perfectly fine the rest of the day and the
next. 2 days later my truck cannot go over 25 mph
and the rpm’s keep increasing. What’s the problem
and what should I do? Thank you for you help in
advance.
