Is a 2002 grand prix 3.1 trans the same as a 2002 3.8 motor grand prix?

Been looking all over and I'm confused. I know sometimes the plugs are In different spots but I need an idea of what will work. I have a trans from a 2001 se 3.1 grand prix. Just trying to figure out what else it will fit. I take it its a 4t60e?

• 1997 Pontiac Grand Prix 3.4 DOHC V6
• 1997–2003 Chevrolet Lumina/Monte Carlo V6 3.4 L/3.8 L
• 1997–2003 Chevrolet Venture V6 3.4 L
• 2000–2003 Chevrolet Impala V6 3.4 L/3.8 L
• 1997–2001 Chevrolet Lumina/Monte Carlo V6 3.1 L
• 1998-1999 Oldsmobile Intrigue V6 3.8 L
• 1998-2003 Pontiac Grand Prix V6 3.1 L/3.8 L
• 2004 Pontiac Grand Prix V6 3.8 L
• 2006-2007 Chevrolet Malibu (SS Models) V6 3.9 L

But some threads I found say they will not work...

If your engine is the 3.1L it's the 4T60E: http://en.wikipedia.org/wiki/GM_4T60-E_transmission

From 2000+ it is the 4T65E

The article says 1993-1999 Pontiac Grand Prix "GT" 3800 V6 (L36 Motor). The 4T60 was a terrible tranny btw.

4T65E:
1998-2003 Pontiac Grand Prix V6 3.1 L/3.8 L
1997 Pontiac Grand Prix 3.4 DOHC V6

4T60E:
1993-1999 Pontiac Grand Prix "GT" 3800 V6 (L36 Motor)

Up to 99 some cars with the 3.8L had the 4T60E. My buddy's 98 has the 4T60E

No his was a 3.1L Base model.

Thanks so much guys.. So I guess in my case they are the same.
