Ok fellas got a big ass problem....t-case in 02 blew up

[rockola1971]

i have seen parts listed like before but gm had there head up there butt during that changeover so when i had my 00 I learned pretty quickly to order for 01, the 03+ stuff looks pretty close but won't fit, I was told some of the 03+ transmissions can be swapped if the bell housing is swapped or something? just what i was told once

I learned the hard way completely opposite of your situation. I had a 99 GM Sierra SLT Z71 and it had the Vortec 5.7L 350. I had to order parts for a 99 K1500 or I would end up with the newer body style(at the time) parts like different suspension and even engine (LS Style) if I even thought about ordering for a 99 GMC Sierra Z71. 99 was a screwed up year for GMC because they made both body styles (generations) that year. Old model had 3 doors and the newer model had 4 doors.

That old truck and vortec is still going! Original engine. I bought truck with like 82K on it. That engine has over 300K on it now! Thats unbelievable for a vortec 350 chevy. The spiders have never even been replaced!
