The 1984-87 Ford F-150 top shift overdrive (TOD) is a four speed manual transmission with fourth gear as an overdrive.
This overdrive transmission was made for Ford by Tremec, and it is known as a T170FT RTS. It was produced in three different overdrive ratios for use in Ford F-150 (and some limited F-250) full-size light-duty 2WD and 4WD pickup trucks.
This transmission has been a popular choice for Model A and early V8 Ford overdrive conversions, and a number of people have made complete kits available to do the conversion swap.
Ford Parts and Service Division
Service Manual Description:
The top shift overdrive (TOD) is a four speed manual transmission with fourth gear as an overdrive.It is fully synchronized. All forward gears are helical-type and are in constant mesh. The forward gear changes are accomplished with synchronizer sleeves.
Reverse is provided through a reverse idler sliding gear which slides on a reverse idler gear. The reverse idler gear is in constant mesh with the countershaft gear. In reverse the spur-type gear on the reverse idler sliding gear meshes with the gear on the 1-2 synchronizer hub.
The top mounted shifter operates shift rails in the transmission cover assembly. The first-second fork and the reverse fork are attached directly to these rails.
The third and overdrive shift fork is attached to a shift rail which is mounted in the transmission case.
Third and overdrive are shifted by means of a shift pawl mounted on a rail in the transmission cover, contacting an overdrive shift control link in the transmission. This shift control link contacts the shift fork in the transmission.
A shift interlock system located in the transmission cover prevents the engagement of more than one gear at a time.
The transmission case, cover, and extension housing are aluminum. The mating surfaces of these components are sealed with Anaerobic Sealer (Gasket Eliminator).

Tremec T170FT RTS TOD Specifications
The overdrive ratio of a Tremec RTS transmission can be identified by a sheet metal tag which is riveted to the front RH side of the case. This is useful when evaluating a loose transmission at a junk yard or swap meet.
The first three characters on the tag should be 'RTS', and be immediately followed by a two-character alpha code as shown above and in Column 1 in the table below. The two-character alpha code will identify the overdrive ratio as originally built.
Beyond identifying the OD ratio, the various Tremec two-character alpha codes identify the original up-assembly as being for a 2WD or 4WD, and which speedometer drive gear they were equipped with. Other than identifying the OD ratio, the RTS alpha code is unimportant in adapting the Tremec to the Model A or early V8 Ford.
The various other codes stamped on the tag identify the production date, the Ford service designation number, and the Tremec unit serial number.
Additionally, there is a Ford part number and a Tremec part number cast into the LH side of the aluminum case. The first style case is marked RF-E4TR-7006-AA and C-2604877, and the second style case is marked RF-E5TR-7006-AA and C-2605524 (8 hole butterfly front mount).
You may also find similar four speed top shift aluminum case transmissions, but with no Ford casting numbers or logo, and having only a Tremec case number C-2605275. These were made by Tremec, but are not marked 'RTS' on the steel tag. These may not be overdrive, and may be 1:1 fourth gear ratio.
For reference, the Transmission Codes table below also shows the Ford and aftermarket part numbers and tooth counts of the various gears in each RTS transmission configuration.
Specification compilation courtesy of Al BerryGreen-shaded cells indicate parts which are still generally available new in the aftermarket.

IMO, the 'Goldilocks' Tremec transmission for a Model A would be a combination of the the 1st and 2nd gear ratios of a Ford 'Code C' transmission, combined with the 4th gear overdrive ratio of a 'Code B' transmission.
Ipad apps free writing. Unfortunately, however, such a 'combination' cannot be physically configured from the selection of component parts ever produced for the RTS. Refer to the Drivability and Suitability ~ Recommended Combinations section at the bottom of this web page for further explanation of why that configuration would theoretically be the 'Goldilocks' solution.
The RTS/TOD transmission overdrive ratio as-built can also be identified by the Ford transmission code printed at the bottom center of the VIN/GVWR/Tire Information label (applied inside the drivers door opening) of a Ford F-150 pickup truck, as shown below.
1987 F-150 2WD Regular Cab, Six Cylinder with Tremec 27.6% OD Code B
The transmission will be a Tremec T170FT RTS overdrive transmission if the label identifies the transmission as a code 'B' (27.6%), code 'C' (37.9%), or code 'D' (41.1%), respectively. This information is illustrated in Columns 2 and 3 in the table above.
Installation Considerations
It is recommended to use the Model AA truck four-speed transmission clutch (bell) housing rather than the Model A three-speed transmission clutch housing as the basis for the conversion.
The 1929-31 Model AA truck clutch housing is shorter fore-aft than a Model A three-speed housing and its use requires less (if any) modification to the frame center crossmember for clearance to the transmission and U-Joint covers.
Both the Model AA and BB truck clutch housings have the same critical dimensions. The inside diameter of the opening for the transmission front drive gear retainer is 4-3/4 (4.750) inches. The fore-aft dimension between the flywheel housing contact surface and the transmission case mounting surface is 5-9/16 (5.5625) inches.
The Model BB clutch housing does not have any front radius rod (wishbone) mounting provisions compared to a Model AA housing, but the BB housing is necessary when using a Model B/BB flywheel housing and oil pan. Model AA and BB housings are not interchangeable with each other.
Use of either the Model AA or BB clutch housing does however require fabrication of brake and clutch pedal mounting provisions. A provision for mounting the emergency brake handle to the transmission must also be fabricated.
The shift lever opening position in the floorboard and mat is slightly affected, moving rearward.
The system conversion based on the Model AA clutch housing also requires the shortening of the Model A torque tube, drive shaft, and rear radius rods approximately 1-1/2 inches.
Modification to the Tremec transmission itself involves:- Drilling and tapping the front of the case for the Model AA clutch housing attaching bolt locations.
- Reduction of the front main bearing retainer diameter size to fit the Model AA clutch housing.
(for reference, the stock Tremec diameters are 4.850 inches and 1.430 inches) - Enlargement/sleeving of the front main bearing retainer diameter to match the AA throwout bearing hub.
- Shortening of the (main drive gear) input shaft pilot nose length by about 5/8 inches, and removal of about 1/4 inch of spline length from the front of the shaft.
- Replacement of the tail shaft extension with a suitable rear bearing retainer adaptor plate.
(for reference, the stock Model A rear bearing retainer thickness is 1-5/16 (1.3125) inches between the gasket mounting surfaces.) - Shortening, splining, drilling and tapping of the rear of the transmission output (main) shaft for mounting the Model A universal joint.
- Adaptation of the shift lever to suit the user's needs. A 1980-86 Jeep T176 one-piece cane shift lever can be easily adapted to replace the Ford stub shifter shaft. Search for Crown Automotive 5359835 shift lever.
- A very nice 1-7/8 diameter black engraved 4 speed shift knob (3/8'-16) is available from core-shifters.com to fit the Jeep lever.
The Model AA throwout bearing hub, clutch release shaft, arm, and pressure plate are used.a 1949 Ford clutch disc. A Ford 8N-7550 clutch disc, A C5NN-7600 pilot bearing and C0NN-7580-A throwout bearing can also be used.
Alternatively, a 9 inch diaphragm pressure plate and matching clutch driven disc for a 1983-88 Ford Thunderbird or 1984-86 Mustang SVO 2.3L turbocharged four cylinder can be mounted to a lightened and faced Model A or B flywheel by drilling and tapping six additional holes. The Thunderbird's 9 inch clutch disc hub has the same 1-1/16 inch x 10 spline as the Tremec RTS input shaft.
Drivability Considerations
Overdrives are a Physics problem, not just a Mathematics problem!
Increased Torque and HP at the right RPM are required to go faster, not just mechanical overdrive gear ratios!
Any vehicle would benefit from the added engine torque and horsepower of a 5.5 or greater compression ratio cylinder head and a Stipe IB330 camshaft.
Essentially, top vehicle speed will occur when aerodynamic drag equals power output.
Proper gearing keeps the engine RPM in the useful range between 'just below max torque' to “around max power” for all road speeds.
Proper gearing keeps the engine RPM in the useful range between 'just below max torque' to “around max power” for all road speeds.
Improper gearing results in lugging the engine at low RPMs and destroying Babbitt engine bearings!
Lugging occurs when the engine is operated under load at below peak torque for any length of time.
Also, don't forget to improve your brakes!
