So last year i bought a 95 grand prix and was warned the transmission leaked. I took it to my local mechanic and he said he couldn't find any leaks. I keep checking the fluid, it is always below the hatch line. So I fill it, go for a drive, check it again, at the exact same level. I have never seen any signs of leakage on the ground. Is there something I'm not getting? maybe its simply someone has the wrong dipstick in there and I simply fill it till it overflows? but then that raises the question of why wouldn't I see the fluid on the ground?
Any help would be greatly appreciated
