This transmission is built using MFactory Pro Series 1 - 4 Drag Gears and Synchrotech carbon synchros, bearings, seals and factory limited slip differential (unless specified otherwise). The gears are designed with a longer 1st and close ratios 1 - 4 for a better launch, reduced RPM drop during shifts and the ability to drive through the traps in 4th gear for most setups (no more shifting to 5th!). The OEM 5th and 6th gears are reused for highway cruising. The gears are hardened and super sub zero cryo treated for increased strength. We recommend upgrading to a 4.39 final drive if you have a 9th gen Civic or if you plan on trapping over 135 mph in the quarter mile.

Ratios: 2.313 1st, 1.650 2nd, 1.304 3rd, 1.080 4th

Core must be supplied by customer, contact us for pricing if one can't be supplied!
