The Tremec T170 RTS TOD is getting harder to find hard parts for too. The one thing that favors it is the shift tower location is closer to the old Fords and at least it does have an overdrive even if it is only a 4-speed. The use was from 1985 through early 1987 in Ford F150 and Bronco 2WD and 4WD. There are several applications depending on engine and rear axle gearing. Some are better than others on the highway. All this puts them in a less used and less available category than the multitude of T5 transmissions. The T170 TOD was made at the Tremec plant down in Mexico and the hard parts have not been manufactured since the 1990s. They get mixed up with their close relative like the SROD and the SMOD but only some of the gear parts interchange plus shifters & cases are different. Many TODs ended up in Model A conversions and quite a few were set up for the later Fords of the flathead V8 era. The popularity isn't what it used to be due to lack of support. The T170 TOD works just fine for regular driving. It's not the strongest unit and it wasn't made for heavy load hauling but it will take the place of an old Ford top loader just fine since they weren't all that strong either.
