Will a 99 3.8 grand prix transmission fit 2002 GTP?

No, a 1999 Grand Prix 3.8L transmission will not fit a 2002 GTP. The 2002 GTP uses a different transmission (likely a 4T65-E) than the 1999 Grand Prix 3.8L (which likely uses a 4T60-E or similar, but definitely not interchangeable). Even if the bolt patterns might *seem* similar, the internal components, bellhousing, and overall dimensions are different enough to make them incompatible. Attempting to install it would likely cause significant damage.
