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 900Æs 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-2.87á 2nd 1.89á 3rd-1.28á 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.
