TREMEC TCET4615 Ford TKO-500 5-Speed Overdrive Manual Transmission
TKO, 5-Speed Transmission Speeds, 500 ft./lbs. Torque, 10 Input Shaft Spline Count
Far and away the most versatile 5-speed transmission on the market, the TKO offers an impressive array of flexibility features – including multiple shifter locations, mounting configurations, gearing options, and speedometer pick-ups (electric and mechanical).
Serving up 500 lb-ft of torque capacity, along with confidence-inspiring shifts and fuel-saving overdrive, the TKO-500 offers an ideal blend of brute strength and street manners – which may be why it's the manual transmission behind more boulevard-bruising street machines and sportsman race victories than all of it's competitors combined.

TKO-500 Service Manual (PDF)
TREMEC TKO transmissions can be shifted from three different locations - front, mid, and rear. From the factory they are configured as a rear shift. To change the location, you must purchase a mid or front shift kit (sold separately) and the rear shifter location is capped off with the provided plate.
TREMEC TKO transmissions are a great replacement for Ford toploader four-speeds as they have been configured to bolt up to the stock Ford bellhousings. Keep in mind that TREMEC TKOs are larger and taller then their 4-speed counter parts. The only parts needed to convert from a three or four speed is a cross member, shift lever, shift ball, and shorter speedometer cable. The driveshaft length is not affected for the Ford conversion as the transmissions are the same length. The slip yoke may have to be changed to match the output shaft.
