79-95 Mustang Tremec 5-Speed Hd Transmission (Wide Ratio)

This TREMEC transmission is from Ford Racing #M-7003-R58W

The LRS-TKO500 is equipped with a 10 spline input shaft and a 31 spline output shaft. Gear ratios: 1st 3.27; 2nd 1.98; 3rd 1.34; 4th 1.00; 5th 0.68 (Wide Ratio)

Features improved shift forks, one-piece counter-shaft, gears made of 4615 steel which increases the torque capacity over that of the M-7003-R58 model

Designed to be a replacement of the earlier model TR-3550, the TKO has been significantly upgraded, making it more robust, flexible and versatile. The TKO is ideal for high-performance racing applications.

Features & Benefits:
* Higher center distance (83 mm) from main shaft to counter shaft allows for larger gear sizes and higher torque carrying capacity

* Close gear ratio (2.87 & 3.27) models available for high-performance racing applications

* Robust transmission design with internal 3-rail shift system with cast iron shift forks

* Tapered roller bearings on input, output and counter shafts improve performance (reduced noise factor).

* All gears and shafts made from special grade steel (ASTM 4615) that permits increased torque carrying capacity

* Single-piece countershaft that better handles increased torque carrying capacity

* Equipped with a high-performance short-throw billet aluminum shifter that isolates road noise, while providing clean crisp shifts

* Neutral safety switch and back-up light sensor

* Flexible and versatile:
o Eight shifter locations available
o Dual electronic and mechanical speedometer pick-ups
o Three unique cross member-mounting configurations
o Three different input shafts available

o Three available overdrive ratios
+ .64 or .68 ratios reduce engine rpm to a level that makes it fun to drive besides enhancing the fuel efficiency
+ .82 ratio is ideal for long straight-aways for high performance racing

Requires a unique bellhousing FRPP# M-6392-R58 to install in a 1979-95 Mustang

To fit in a 1979-1993 Mustang use M-5059-A crossmember

To fit in 1994-1995 Mustang, modify vehicle crossmember, lengthen driveshaft .625" and use clutch fork E6ZZ-7515-A

31 spline driveshaft yoke required

Can be used in 4.6L applications with bellhousing M-6392-M46
