T45 5-Speed to FE--Possible?
« on: September 01, 2019, 08:54:40 AM »
Hey guys. Sitting here thinking about putting a manual transmission behind the 410, when I get it installed in the '89 F-150.
I have a 1999 Mustang GT Convertible 5-speed car sitting here. It's beat. The 4.6 has a rod knock due to an oil pump failure, and I got to thinking, hmmmm, I wonder...….
I know I'd have to do something about the speedo drive as the Mustang T45 uses a sensor to drive it rather than a cable.
However the biggest thing I think, would be the bell housing. It is part of the transmission if I'm not mistaken.
Heck, the shifter may come too far back as well, I don't know, I've not done any measuring.

You guys ever hear of someone installing one of these behind an FE?

The easiest way would probably be to install the 4.6, T45 and pedal assembly from the Mustang but I really want the 410.

Anyhow, too much work? Would it even be possible?

Thanks for any input.

Found this on the web, so it looks like it's possible but is it worth the trouble? Scroll to the last post.

First of all, you need a 4.6 engine. The T45 won't bolt up to a 289.

You'd need a custom bell of some sort, I would think. There is a reason that T45 swaps in classics are rare... and its because you could do a T5 that is comparable in every category and will bolt right up.

But, then again, there is value to being unique and doing it your own way.

i had a 302 on my engine stand and i swapped it with a 4.6 and the block to bellhousing bolt patterns were the same so im sure its possible... the only problem i think is the pilot bearing and clutch combo..... i checked with D&D transmission. they said it was not possible and that the T-5 was a better option... or tk-500/600 or if you want to spends wayyyy to much money go with the t-56... someone in the 5.0 tech section may know a little more about this... the fox guys are pretty good about fitment questions... id try posting in there too.. or call D&D transmission (248)735-6220... located in michigan. wixom i think. google "d and d performance" it will be the first result. they are very helpful.

I bought it anyway. I am not in a position of finding these kind of things second hand in any way. I am in Turkey. So if it is possible, I will keep it. If not, I will try to give it back. I cannot change the engine by the way. So is it possible or not with my 289? What do I need to buy / do? Thank you very much.

First step is confirm that the bellhousing will or won't work. Find a 289/302 or take your trans out and see. If it works, then one major hurdle averted. If not, that could be an issue.

Second, you'll need to figure out how to do a crossmember, and this will likely have to be compeltely custom fabbed by you or some machinist. You'll probably need to fab it up, or at minimum take some incredibly good measurements.

As someone else said, you'll also be challenged with the clutch cable positioning. You'll have to fab that up to make sure there is room between the transmission and the car's frame/body to have a clutch cable.

Do all that and report back. Let us know.

ok.. Today my mechanic called and told me that he will definitely install the transmission. I understood that he tried it on some other engine.. The thing is the shifter will move 4 cm backwards and we will have to use a custom shifter. Other than this I will write the updates. I just hope that he is not calculating anything wrong

I decided on a T45 for my 67' GT with a 428cj
Being a Ford dealer tech and having spare parts around the shop, I put together a T45 with the adapter from The T45 Source. Plus another adapter/ spacer to rotate the assembly 7.5 deg. CCW and space the trans an half inch to correct the input shaft length. Picture are on photobucket in hubstang's albums.

Won’t hold up too well. They are only rated for 400 lb-ft of torque so your 410 will likely break it pretty easily.

That adapter doesn't seem to be available any more and i'm too cheap anyways. I was going to use my T45 behind the V10 but that isn't going into the Ranchero any more and thought i'd use it behind an FE>
 looks to me like if I cut the OD of an FE flywheel down to take a 164 tooth smallblock ring gear it will fit inside the Mod Motor bellhousing then the only thing to adapt is the bolt pattern and dowels.

Have you decided what you are going to put in that thing yet? If I could find a decent pinto and a moon tank, I'd bang a straight axle under it, buy the V10 off you and fab a 5x94's ram log for it, like we talked about... :o ;D Gasser! GASSER!! ;D

I think I need to find you a Pinto! Nobody with a 2005-up truck works on them so that market is dead.

Then i'll use the T45 behind a 428 and test it's strength.

That would work, not sure why the adapter needs to be so thick.
