This past month, the transmission in my 2008 Suburban LT3 4 wheel drive sent me limping home in low gear. I immediately began searching for a replacement transmission. I found a builder who had one ready to exchange for my 4L60E. I begin to install the transmission and have it in place on the dowel pins to bolt up. In the process of installing the top transmission housing studs the stud hole to the right of the top hole is off location from the back of the engine block. My Suburban has the aluminum block LC9 motor. I would like to know what the proper bell housing part number is for my Suburban so I can get back with the builder and have him provide me with the correct one. Unfortunately, I didn't take pictures of the transmission that I exchanged. The part number on the bell housing of the transmission I bought is 24206952. My VIN number for the Suburban is 1GNFK16358R141754. I have done an online search for the correct part number and the GM dealership sites along with others don't provide the part separately. I have only been able to get a part number for the entire transmission. If anyone reading my thread can help, I would appreciate it as I would really like to get my Suburban back on the road.
