What Overdrive Transmission is this?

[JRN1967]

It's a T170 or RTS, see link below. I did my own conversion using this transmission last year. The difference is night and day. The ability to make quick synchronized shifts maximizes your hp enough so you can drive in normal traffic. Being able to downshift saves on your mechanical breaks.

The OD gives you more top speed while lowering you limited RPM's and prolongs engine life.

Did you have to shorten the torque tube?

It is a F150 Transmission 4 speed w/OD. The pictured installation uses a Model A bellhousing. They are excellent transmissions. I did my own conversion using a AA bellhousing. Have driven it several thousand miles on cross country road trips with no trouble. The AA bell housing eliminates the need to cut the center crossmember plus the gear shift lever is very near the original location. Three OD ratios are available. They are getting hard to find as well as replacement parts.
