MMR Pro Trans 900 5 Speed Upgraded Tranmission

$2,799.00

This is our street/competition transmission and the same that we use to hold the current 5 speed record. These transmissions are derived from a NEW TKO 600 unit. 1st, 2nd ,3rd & 4th gear along with the cluster gear receive a heat tempering that 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 increase the Pro Trans 900's strength. Upon re-assembly the factory thin sheetmetal inspection covers are replaced with thick CNC machined case supports to provide further case support to help minimize case flex. A few other proprietary modifications are completed before the transmission is re-sealed using the factory type sealer, 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

5th is available with .68 (common and similar to stock 5 speeds) or .82 (closer ratio for road racing- will rev higher on highway). *


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.
