No. As there are three different engines that can be in that model in both years, the numbers for the alternators do not match for any of the engines. The mounting locations do not align, and the 2001 uses a 110A alternator while the 1998 uses a 105A alternator,

everything will cross over but the engine and transmission in the gtp are suppose be heavier duty built

other then

• Buick Century
• Buick Regal
• Chevrolet Impala
• Chevrolet Monte Carlo
• Oldsmobile Intrigue
• which are classed as related to the 98 grand prix , which is the 6th gen gran prix years 1997-2003, hope this helps

As you see I provided you the models you can apply the transmission :The 4T65E-HD (code MN7) is a heavy duty version of the 4T65-E used with more powerful engines such as the LS4 V8 and L67/L32 supercharged V6. Applications: 2.93:1 MN7 Pontiac Bonneville SSEi L67 Chevrolet Impala L67 Chevrolet Monte Carlo L67 Pontiac Grand Prix GTP/GXP Buick Regal GS Buick Riviera L67 (97-99) So ,yes you can!

You can replace it as long as the one you are replacing is the same set-up. If you have a manual adjusting seat and replace it with a power seat it will fit but you wont have the hook ups for it. Also make sure if it is a bucket seat (single person) you dont replace it with a bench (3 persons fit in front) seat or you will run into problems with the center console and shifter. vice versa may bolt up but there will be a gap between the 2 front seats

You will only be able to fit a 3800 engine in this car. If you would really want to swap a different motor a 3800 superchanged L67 engine will fit but you will need a heavy duty tranny from the 3800 motor and you will also need a wireharness injectors and harness and also a PCM. You can find these motors for a pretty cheap price on moradparts from ebay. They also have their own website. Very very good place to buy used W body GM parts

some generalmotors cars you had to use an adapter which you can get at most automotive stores like autozone you screw it on over the smaller unit and you leave it there then you can fill it

yes will fit no problem
