Ok, i have this ford t 10, was told its a super but i dont think so. I got it to use with a 390 and anyways, started digging around the hamb to try and identify what I have. After stumbling across some other bummer info, that being the ford transmissions are small and big block specific. As in small blocks have a smaller diameter pilot shaft in front and a smidge longer than the FE i think I read. I also measured the tailshaft at 14" so is this a small block falcon transmission and wont work on the 390? So, I think I have a ford 4 speed I dont need if thats correct. Pictures included and as always thanks for the info! Timothy And if anybody needs it, holler
The pictures show me a small block trans from a falcon. Is there still a tag bolted on with the tail housing? That will tell all. That trans can be used on a 390 by just shortening the polit bearing area as already mentioned. But before doing anything with it, count the out put splines. I think it is not going to be 28 spline which is common. If it's the 25 spline, good luck trying to find a slip yoke!
The output splines fit the driveshaft we have so we p***ed that hurdle. The transmission in the truck (66 f 100 short) now is a granny low 4 speed. Now the next hurdle is the clutch splines. We have had the engine out before doing freeze plugs etc and I remember the trans (t18 i think) was a co**** spline so am thinking we might be good there. We will pull the trans out today and get to checking the basic stuff and if the shaft is correct splines and diameter, we will jump the length hurdle next and chop and shave to match. Thanks! Timothy
Dang, further inspection reveals my old ***ed brother cant see and our driveshaft is bigger than the little 25 spline tailshaft we have! You were absolutely 100% correct! Thanks Timothy
I know nothing about T18's, but basic clutch splines were 1 1/16 - 10 spline and the big one at 1 3/8 - 10 spline. No T10's ever came with 1 3/8 spline inputs. You should be able to find a disc in whatever size you need with your 1 1/16 spline.
Somewhat related........... In the early 70's I had a 57 Chevy with a T-10, started popping out of second gear, found a rebuilt one at a transmission shop that had built it for a drag racer that never got picked up, it had the stronger Ford ge****t installed in it, had to use a Ford clutch disc, worked great, I bet someone had a big surprise when time came to change the disc!
Yes, the input shaft can be shortened. Yes, clutch discs are pretty universal; no problem finding one which will fit. Since it's going in a truck, make sure you get the largest diameter which will fit your pressure plate. Yes, the output spline yoke is not common, but still available. A driveshaft shop can match the yoke to your driveshaft. Yes, you'll be making your truck less butch by installing the car T10 and not changing the highway RPM at all. Yes, you'll need a longer shifter handle. jack vines
That T10 will directly bolt up to your truck bell. Virtually all Ford car/light truck Manual trans had the 1.125"/ten spline input up to about '64, most after, only the big-block Ford-built toploader had the bigger one. DO NOT shorten the pilot shaft as the truck FE bells are .350" deeper than the car bells just so they could use the longer pilot shaft. You'll find that the truck trans will have the identical longer pilot shaft. Should you use it behind a 390? Weeell, maybe. Ford stopped using them behind most FEs as soon as the new toploader was available in any numbers in '64 after experiencing multiple failures in '63. Ford had intended to just drop the T10 altogether, but getting their new transmission factory up to full production and more demand than anticipated caused shortages so it soldiered on behind many small blocks until about late '66 when the toploader fully took over. The T10 was a '50s design for mid '50s power levels, by the early '60s it was obvious to all the OEMs that the larger motors were exceeding its limits, and the big 3 OEMs moved on from it. Don't beat on it hard, it'll live. Besides its power limits, these are also known for popping out of gear on deceleration if the syncros get worn, finally addressed when they did the 'super' upgrade.
My 51 willys is same way. I have a ford 302, a gmc transmission, a willys transfer case, Herm overdrive and full sized dodge axles. I kept a list of part numbers of clutch, pilot etc etc for when /if I ever sell it.
Gteat info, thanks, I am already in the mindset of keeping the very beefy t18 and keep and eye out for a 5 speed maybe for the 390. I dunno, I do know, this transmission wont be in my f100. Thanks! Timothy
