F150 tranny with overdrive

[roddyb34]

Macs in New Zealand makes an excellent B/H and is the correct dimension so you dont cut your input shaft ,Graeme is very helpfull when you ring and has the F150 trans on open drive set up in his Riley OHV powered pick up ,check his website WWWmacspeed.com

Correction,,, actually the 91A7563 has the weights, the 8N or 9N 7563 do not. The 91A7563 is listed as a heavy duty replacement for these tractors.

Shifter on the rts is closest to original. The t5 comes up through the floor quite a way farther aft. Rich

How do you measure RPM while in motion, do you have a dash mounted tach. or some other way? If so what drives the tach.

[Jim Parker Toronto]

Yes, I have a steering column mounted 0 - 4000 Sun Tach. It seems to be accurate. Electric, off the coil.

I just wanted to thank Al in NY for the chart on the F150 transmission.

I have an '86 F-150 OD aluminum case tranny for sale. I had it behind a flathead and went to a t-5. PM me if interested.

trctrdr. i am one of the kit builders Al in NY mentioned. Name is Ken Parker. If you will call me or email me I can give you the info you need to "fix" the input shaft and the throwout hub. [email protected] or call 903-963-1650.

You want the T170FT CODE RTS. ...You will not disappointed! No modifications required to the cross member or brakes!!!

The best choice by far!!!

Another source for a Ford F-150 OD transmission is Sheridan's Repair in Nunica, Michigan. Call Tim Sheridan at 616-836-6477. His is a "drop in"
tansmission, not a kit, that does not require any cutting of the center cross member. Tim has made and sold his conversion for a number of years. I purchased and installed one earlier this year and am quite pleased with it. Tim explained to me that there are 3 different OD ratios that Ford offered with these transmissions and I strongly recommend that if you purchase one get the OD gear ratio that best suits your engine and your normal driving conditions. If you live in hilly or mountain region you would not want the highest OD gear ratio available as it could result in lugging your engine too much. Sheridan transmission conversions use the standard Model A bell housing.

Could someone explain how to determine the different OD ratios by looking at the metal tag on the right side of the tranny?
thanks nick

Go back to the chart from Al in NY...... Post # 8. That's my transmission RTS BV. Find that on the chart, and then go across and look at the numbers.

[AL in NY]

MurphyJ, it's not possible to install an F150 transmission in a Model A using the standard Model A bell housing and NOT modify the crossmember and brake cross shaft. I think you mean that Tim sells his kits using the Model AA bell housing, which then make sense.

[MurphyJ]

Thanks Al, but recently did install one of Sheridan's F150 tansmissions in my 1930 Model a pickup without having to us a AA bell housing or modify the crossmenber. Granted it is a tight fit between the rear of the tansmission and the crossmember but no mods to the crossmeber were needed. I did have to shorten the drive shaft, torque tube and radius rods and a slight alteration of the brake crossover shaft, and that was all.
I have a couple of photos that I can share if you or anyone would like to see.

[AL in NY]

MurphyJ, Yes, please post. Would like to see how you did your install.

I too would like to see pictures. If the drive shaft was shortened, it means some big stuff was moved back--I wonder how. There wouldn't have been much room for the U-joint in my car.

I'm not sure, but I think this is the table for the F-150 trans we're dealing with:

[MurphyJ]

Below are some photos of the Sheridan F-150 OD transmission I recently installed. Keep in mind that I purchased only the tansmission from Tim Sheridan, not a kit. I specifically did not want to cut or modify the cross member. Also, if I or a future buyer wants to reverse the OD transmission and return to the original transmission set up, it is possible. Upon receipt of the transmission, I had to shorten the torque tube, drive shaft and radius rods, all approx 4 1/2 inches, working with a local one man machine shop. All the labor of the installation I did with the help of another shade tree mechanic. The first photo shows the transmission installed between the cross member and the "A" bell housing. Photo 2 shows the slight interference between a bottom bolt and the brake cross over shaft. Photo 3 shows how that interference was eliminated by altering the brake cross over shaft.

[Jim Parker Toronto]

Yes, that would be the correct table to look at when you are going by the tag. My tag said RTS BV, as posted in reply #8 of this thread. So then it would be in the first group "302 V8, Trans ID RTS-" and then follow down to the "BV". This would in no way mean that someone has not changed the gears inside, but could be used as an indicator.

[CarlG]

My tranny does not have the tag on it, but I have been told (by the builder) that the gear ratios that are in there are: 1-3.25, 2-1.92, 3-1.00, 4-0.78, R-3.25. Don't really know if that is what this particular tranny had in it originally or not, but that's what's in it now. Per the builder, this is what is optimum for use in a Model A. This is also the same as what Jim Parker has in his.
