Description

B&M Transkits give you the same high-quality components that are used in all B&M Street and Strip transmissions. They include high performance friction materials, a complete overhaul gasket set, a drain plug kit, and all of the parts necessary to convert your valve body into a full manual/automatic valve body. These improvements enhance shift feel, while retaining full automatic features. The Transkits come complete with full instructions on how to assemble your transmission to B&M specifications (except BMM-70232 and BMM-70233). They also include special directions on how to modify your case, pump, and components.
