Sounds good but our delimna is the y-blocks. There is no easy way to modify the engine to put a modern auto or manual without spending serious money. It prevents you from keeping the y-block. Ed

Y Block Trans
Many of the mid 60s thru 80s stick trans had both the early and late trans bolt patterns . Sometimes the input shaft retainer has to be turned downed to fit or the throwout fork has to be modified to use the larger throwout brg some of the old trucks have . I hope this helps . GOOD LUCK !!!! HOTWRENCH

Y Block Trans
I have put 70s 4spd car trans [ mustang fairlane ] in my 55 @ 59s With a 292
without too much difficulty. The pilot bearing was the same, i had to turn the
front bearing retainer down, Unless you use a big shaft car 4spd the throwout
bearings are the same, as is the clutch splines. I modified a shifter to fit. Started with one from a 67 Fairlane. Some tailshaft houseings have the shifter
mtg holes at the back these require a little more work to make the shifter work
Fabricated driveshaft @ crossmember mts. Some long tailshaft 3spds @ 4spds
are the same length.

The bolt pattern on the T5 is different. I bought a 3 speed bellhousing that was modified for the T5 from John Mummert but when I saw how it was done, anyone that can weld could do it. 3 of the 4 bolts match up. The fourth bolt was made to fit by welding a threaded bung to the bell housing. That's all there is to it. You will need a modified throughout bearing and the bracket from John to use the original clutch linkage. The input shaft will fit but you may need to trim a little off of the pilot depending on how deep your crank shaft is drilled. Be sure you get a T5 from a V8 car. The pilot on the 4 or 6 cyl trans is too small for the pilot bearing in the flywheel. Learned that the hard way.

The shifter on the T5 is at the rear on the trans. This may put it too far back for a bench seat. I will have to do some measuring to find out for sure.

I am going with the T5 since I have seen how easy that is and I can keep my y-block. Plus it is the cheapest way to go so far and will get me on the road by the end of the year. Ed

You can buy an adapter or ask someone here that has one to send you a template. Go to www.ford-y-block.com for the part if you want to buy one. Ed

A lot of the Ford top loader transmissions had both bolt patterns on them the wide one and the more square one. so they could be bolted up to early model bell housings and the late model hosuings. I have also seen bell housing that would accept either bolt pattern. I have had bell housings that where not drilled and tapped for one of the patterns but had the bolt boss's cast in them that allowed me to drill and tap. The point is do some searching around some of the older salvages and you will come up something that will work. Also the Fmx auto transmissions bell housing is a bolt on unit and can be changed to fit different blocks

I have a tranny out of a 84 F150 I thought was a T18 / T19 The tranny pictures on the Novak site confirm this However the top cover is Aluminum?? The T 18/T19 according to the site have cast tops. The casting #'s on the side are as follows

Were it me, i would go with the late 60's FMX, not only is it a strong transmission, but i knoew of one being installed, and i think the torque convertor bolt up was the only issue that had to be fabricaticated..That FMX was used on many of your cleveland egines in pickups, you can find one at a salvage yard. they are rather easy to ifrntify, because unlike most automatics they had cast iron for your mid section, i would go that route..Janet
