I have a newly acquired 99 GTP with 70K on the rebuilt transmission. I has a bit of a clunk going from park to reverse and when it shifts around 30mph. I checked the fluid level after driving about 30 miles (sub freezing temperatures currently) to warm it up, did the shift to all gears and idle a few minutes thing, and showed no fluid/add half quart. I ended up adding a whole quart, about four ounces at a time, shifting and idling a few minutes each time, and still doesn't register. So I'm guessing it needs at least another half+ quart. My concern is I'm missing something stupid and overfilling it - which I hear is a real fire risk when fluid comes out the dipstick. I've seen no obvious leaks in the snow under the car, and the last owner's receipts show they always took it into the dealership for oil changes and attached a checklist showing each fluid level was checked and is ok as of 7K miles ago ... assuming they actually check everything. Can it be a 2+ quarts down and still only have the minor issues I'm seeing?
