I'm sure glad I don't have the 41 in mine. It might be ok in a real light model, or coupled with a 4.11 rear end, but too steep for a town sedan even in the flat lands, IMHO.

The 27% is the one I have in a Fordor. It works fine! 63mph, or 100 kilometers at 2150 rpm.

trctrdr · 09-13-2011, 07:08 AM

The 26 it is.
By the way, if anyone needs a V8 clutch, it's exactly the same as the one used in an older Ford tractor (8N, 9N, 600, and 800) The part numbers are 91A7563 pressure plate, 8N 7550 clutch plate, C5NN7600 pilot bearing and C0NN7580A T.O. bearing. These parts are readily available from any Ford (New Holland) tractor dealer. I have one in my 29 coupe now and it works great.

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.

John LaVoy · 09-10-2011, 09:05 AM

We are working towards installation of a T-5 into the sedan. There is another kit being worked on and as soon as they have things perfected we agreed to install one for the trip to Michigan next year. This kit is suppose to install with out cutting the frame. We will post something as soon as we get our transmission and kit.

Jeeze, if we are talking $3k now, I can install a new Mitchell synchro-ed transmission with a faster 2nd gear ratio, and a 3.27 gear ratio in a fine - point car and do everything you guys are doing and still look 110% stock.

40 Deluxe · 09-14-2011, 01:53 AM

Well, not quite the same! V8 pressure plates have the centrifugal weights on the fingers to add clamping force as the RPM's go up. You can notice this in a V8 car or pickup by revving the engine with the clutch pedal held down. As the RPM goes up you can feel the clutch pedal push back harder. Tractors had no need for these wieghts as they were half the power of a V8 and only ran at 1600-1800 or so RPM.

trctrdr · 09-14-2011, 06:42 AM

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.

Hi there,
Mac's Speed Shop in New Zealand makes a alloy bell housing for this gearbox and I believe they are available in the States?
We have done away with the torque tube and use an open prop shaft, but then you have to deal with the radius rods and possibly fit a torque arm to resist the diff's attempt to rotate

roddyb34 · 09-14-2011, 03:46 AM

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

Jim Parker Toronto · 09-17-2011, 08:31 PM

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

kenparker · 12-13-2011, 07:45 PM

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.

amedic · 12-13-2011, 08:47 PM

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

The best choice by far!!!

MurphyJ · 12-13-2011, 09:41 PM

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.

nick c · 12-13-2011, 10:03 PM

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 · 12-14-2011, 02:31 PM

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 · 12-14-2011, 03:45 PM

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.

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

Tim Sheridan's number is 616-837-6477 not 616-836-6477
