Hi, my name is ***** ***** suercharged and Non super charge use the same transmission in 2004, but there are 3 different transmissions, depending on the code for th trans, it will be either a 4cab, 4lbb, or a 4lcb, so you have to make sure you get one with the correct code,Tim

Customer: replied 2 months ago.
between the 3 different trans, does the bolt pattern change??
Expert:  tsmodie replied 2 months ago.

No, the bolt pattern is the same on all three,Tim

Customer: replied 2 months ago.
what would be the difference in the 3 transmissions???
Expert:  tsmodie replied 2 months ago.

diferent gearing and shift points, they are identical on the outside,Tim

i see, so which one will be best for the Supercharged 3.8?
Expert:  tsmodie replied 2 months ago.

they would all work, just have slightly different gearing, they were all used in the suoercharged engine, you most likely would be able to tell the difference between the 3,Tim

Customer: replied 2 months ago.
i would be able to switch the 3.8 for a Supercharged 3.8 with no problem then correct?
except for the ECM i would have to switch that for the supercharger to work properly correct?
Expert:  tsmodie replied 2 months ago.

yes, and the wiring harness for the supercharger,Tim
