04 GP replacing trans with used one info

[dhdolphns]

Thought I would double check on here, have a 04 GP with a trans going bad , while checking on getting a used one was told that 04 GP are 1 year only transmissions (only a 04 transmission will work) can anyone on here verify that or have an other info on this??
thanks

2004 is not a year only, not sure were you read that or got that information.

Aslong as the transmission from another NA 3.8 GP from 04-08 is should drop in just fine.

The Comp G and GTP transmissions are different because of electronic controls and gear ratio's.

Got it from the salvage yard that I called to find one

the only thing you may have to do is swap in your 3.05 FDR diff in, if the trans is from a bonnie/impala/etc as they may have the 3.29 FDR diff (fdr = final drive ratio)

Got told the exact same thing; maybe it's a glitch in their database, but with the 04s being beta-test cars as it is, maybe there's something in the early production (mine was built 1/14/2004) models that's slightly different, but wouldn't prevent a swap from a newer donor! Still, if there's no difference in the Gen 9 GP's transmissions for L26 cars, that's a relief!
