JASPER Performance Transmissions - JASPER offers two levels of performance transmissions. The Class I Performance transmission is for the individual who wants more performance than stock, but nothing too radical in shift pattern. The Class I transmission does not have a drastically altered shift but will provide firmer, more pronounced shifting.
The Class II Performance transmission is for the serious performance minded individual who wants a transmission that will meet his particular application. These transmissions are built with heavy-duty performance in mind. Special components and procedures are matched to obtain maximum performance for your engine application.
