For TKO and Magnum transmissions

Tremec T-56 Magnum, TKX and TKO transmissions use a Ford speedometer drive and require this adapter or a custom speedometer cable. This package is the easiest and most economical solution to connect to your existing GM 7/8″ threaded cable to the transmission. This design incorporates a double O-ring seal for the transmission case opening, as well as, an internal seal to prevent fluid from leaking through where the cable attaches. The drive spindle is a solid steel swiss machined part for extra strength and accuracy.
