I have a 1996 Chevrolet Monte Carlo Z34 and it has a slow oil leak (maybe about 20 drops a day). A mechanic told me it could be a leaking rear seal, and to fix that, a transmission shop would have to take out the tranny. In the meantime, I am also putting in a can of that "stop leak" fluid.
Taking out the whole tranny to replace this so-called rear seal sounds EXPENSIVE!!! Any idea how much it might cost?
