ls tranny

i have a 1990 ls 4dr. the tranny is a little weak i was wondering if it's better to rebuild it or if i can put a better one in the car? it's an automatic.

Rebuild, buy a used one or do a auto to manual conversion.

get a 5 speed!!!

I would be a bit spendy, but I would say get a 5 speed. If you don't have that kind of money, just rebuild yours.
