Thread: interchangeable transmissions

i have a 99 gt and am about to put a cammed l67 into i figured while its out i might as well change the trans as well being that it is high mileage .... my question is i am not finding alot of gtp part cars locally to me that dont have a high mile trans as well in the 97-03 range. just wondering if i can broaden my search by looking 04 and newer or at another 3800 equipped car (impala regal etc) or if some one knows a spot online where a good deal could be found ...i am a penny pincher.......any help would be appreciated

are the gear ratios different from a gtp or am i ok there

i meant with the ssei and regal gs and such if there ratios were different from a gtp.....also i just purchased a dhp tuner (have no idea how to use it yet) but i will figure it out and have a pcm from the l67 i bought

last stupid question would it work the same as a gtp where a 03 trans would be more sought after due to the hardened parts

04+ trans work in the -03 cars. Use a 03 pcm and tune it for the newer style.

Just transfer the range selector switch to the new trans and speed sensor depending. The only other issue is the cooler lines as the new style uses the push and clip style and the (iirc) 99 and older have the threaded nut style. Just get lines for the newer style.
