no i'm pretty sure '01 and '02 have hy35's with the 9cm exhaust housing and not hx35's with the 12cm housing
HYs came on Autos 9cm in 01/02 The one i have is off my 01 5 speed HX35 12cm

Why is the HY-35 turbocharger used on 2001-2002 trucks with an automatic transmission?
A truck with an automatic transmission has to meet soot emissions standards when torque converter slip allows the engine accelerate quickly. This does not usually happen with a manual transmission because for the engine speed to increase, the truck must accelerate - and that takes time. The HY-35 builds boost a little more quickly than the HX-35 does when the engine load is light, so from an emissions standpoint the HY-35 is better suited to stop-and-go driving with an automatic transmission.
FWIW: The HY-35 and HX-35 are functionally equivalent under most engine loads, and the wastegates on both turbos are set for the same boost level. The HY-35 does not breathe as well as the HX-35 at higher speeds under a heavy load. The choke point of the HX35 is around 35psi; the HY35 chokes at about 29psi.
