hi buddy ive got an australian GM 4l60e case code 1HND2 ect ect. Does the HN or the no2 correlate with anything on your list over there ?The vehicle is a ( holden commodore) a 2000 model GM 3800 s/c v6. RWD with 3.08 non lsd diff. These engines & trannies r made in the USA. But GM had a plant in adelaide sth Aust.The info im looking for is country of manufacture/ assembly ect.

 

Unfortunately my list doesn't include Australia units. Buy the stateside code 1 is a 2001 model year and the H is body code. we don't have an H body, so I assume it is for Holden. i could not find a GM/Holden transmission production plant in Australia.

 

Your transmission would have been assembled in either Ohio, Michigan USA or in Mexico.
Why does it matter to you where the transmission was assembled?

Around 2006 the Holden commodore changed from being on the V-body platform to the Zeta-Body platform.
I am not sure which information that you are looking for?
