The B&M 700R4/4L60 Street/Strip transmission is suitable for use behind engines producing up to 500HP and 450LB FT of torque which covers most small block and mild big block engines. It features a low first gear ratio and an overdrive 4th gear making it a very desirable transmission for street strip applications. This 4L60 transmission is for the electronic speedometer, but is not an electronically controlled transmission. B&M strongly recommends adding a Hi-Tek transmission SuperCooler to help further reduce heat build-up and extend the life of automatic transmissions. Can be used with a B&M Lock-up Controller. Does not fit Corvette or 60 degree V6 engines. Does not replace 4L60E transmissions.
