The outside of your transmission housing case looks identical to a transmission that was built very differently. There are thousands of possible configurations! It’s important before ordering any parts to verify the ID tag data located on the outside of your transmission.
The serial number will provide correct information about your transmission’s specific configuration that we will need to confirm your order. Please help ensure you are asking for the right part by sharing the transmission ID tag data with your US Transmission service professional before you buy. Where is the transmission ID Tag? We have photos and an explanation in our post ‘Anatomy of an Allison 3000 Transmission.’ We encourage you to review the information and provide us with your transmission ID tag so we can make an exact match for the parts you need.
