Tremec Magnum-F 6 Speed Transmission – Close Ratio

Note: the Magnum-F requires a special transmission yoke – click here

Designed to replace aging T-56 transmissions in LS1-powered fourth generation GM F-bodies, the Magnum-F is the latest addition to TREMEC’s hard hitting Magnum 6-speed series. Based on the TR-6060 used in numerous late model factory performance machines, the Magnum-F combines brute strength with modern OEM refinement for the ultimate gear-rowing experience.

Built to surpass even the most heavily fortified T-56, the Magnum-F eliminates the need for over-hyped ‘Stage 6’ or ‘Level X’ rebuilds; along with the concern that comes from rebuilding with inferior off -shore parts.

Aimed first & foremost at ‘98-02 F-cars, the Magnum-F can also be used in third gen and LT1-powered F-bodies with minimal modification; in addition to a host of sport compact applications that previously relied on the F-car T-56 for its ideal shifter location.

Gear ratios:

1st – 2.66

2nd – 1.78

3rd – 1.30

4th – 1.00

5th – 0.80

6th – 0.63
