Transmission and Drivetrain

Modular Mustang Racing has 10+ years of 5 speed knowledge to bring you the strongest, most reliable high performance line of transmissions available today. MMR owner Mark Luton is the driver, builder and owner of the 2000 Red Turbo Mustang, and is the current record holding fastest 5 speed transmission Mustang with an 8.99 @154. This was no easy feat and on his way to this record we learned valuable information that no transmission builder today can match, we have pushed these transmissions to the limit and know exactly what it takes to make them live in our customers cars on the street and at the track. Each unit is hand built by MMR and serial numbered for quality control.

MMR Pro Trans 900
This is our street/competition transmission and the same that we use to hold the current record. These transmissions are derived from the NEW TKO 600 units. 1st, 2nd ,3rd & 4th gear along with the cluster gear receive a heat tempering that dramatically increases strength, each gear is then deburred to improve shifting, minimize noise and increase efficiency which means less drive train power loss than a stock transmission. Transmission also includes 26 spline input and 31 spline output shafts that have been heat tempered to dramatically increase the Pro Trans 900s strength. A few other proprietary modifications are completed before the transmission is re-sealed, serial numbered and shipped to the customer. Each transmission even includes a billet aluminum shifter (handle not included) This transmission is rated by MMR up to 900HP and vehicles running 9.00/150 and slower and requires increased service intervals for race applications. Gear ratios are:1st-2.87  2nd 1.89  3rd-1.28  4th-1.0 and 5th is available with .82 or .64.

* MMR Pro-Trans transmissions are custom items, no refunds or cancellations will be accepted once a custom order has been placed, regardless if the item has shipped or not.
