Quick question about transmission swap?

Hi all once again. I guy I know is letting me have a transmission real cheap. He said it's out of a '98 or '99. I was just wondering if it'll work? I think it should my car is a 2000 model. Both are Grand Prix's. If it will work what are some precautions I should take. What is the easiest way to swap it? Do I need to completely drop the engine and trans together, or what should I do? I recently put all new solenoid in my trans, so I plan to swap all of them over to the new one. Are there any write ups on the trans swap?
 


are both cars supercharged or n/a? if your na you need a na tranny. if sc, you need the hd tranny.

theres a how to here for the trans swap in the diy section.

Neither cars are supercharged. I've just heard of people swapping the trans and the shift patterns being off, and I've searched online for transmissions for this before and it seems that every single one is year specific.. What I mean by that is, I've searched on eBay and car-part.com and when I type in 2000 Grand Prix transmission, the only transmissions that pop up are from 2000 model cars. But I've also seen other people swap in tranny's from other years.. so I'm just a little iffy. Thank you for the info, I will look that up.
 
If they're both NA GP's it should be a direct swap. You MIGHT have to change the cooler fittings. The 2000 is definitely the clip in type fitting. The doner trans might have the flared/threaded fittings. If that's the case, just pull the fittings from the junk trans, and throw them in the doner unit.

Billboost did a really nice write up;

If you have any questions along the way, don't be afraid to ask. I just finished my second swap following this. Pretty straight forward. Just nuts and bolts. Keep everything organized and you'll be fine.
 
Since both are NA. I would decipher both the tags and ensure they are the same gear ratio. If not, flip the differential and sun gears and you'd be all set.
