If I had a t-5 out of a mustang 5.0 can the input shaft be changed out to a 2.3 one and it would work? I can get a 5.0 bell housing clutch,pressure plate and an adapter to get it to bolt up but the adapter is 185.The tranny I can get has no bell housing or clutch parts.It is off of a 91 5.0 mustang. I am guessing the adapter is going to make it not worth it? I am looking for cheaper if possible. Thanks for any input.

Scapper:

I'm not 100% certain of your question so some of my answer might not make sense:

The input shaft of T5 (and many other transmissions) consists of splined shaft (which goes into clutch and gear (which mates with front gear of counter shaft). And the T5 has about a dozen different options... (length, # of splines and # of gear teeth).

The cool part: ALL Ford T5s have 10 splines of diameter 1.0625". So, with correct diameter clutch and appropriate depth bell housing you physically could put any T5 on any engine from 2.3 to 5.0.

But the internals have over 200 different options.

A '91 5.0 Mustang has 23 tooth gear/9.25" over all length input shaft. (later models <'94/95>are longer and take a corresponding longer bell housing)
The 2.3 Mustang has a 19 tooth gear/9.546" over all length input shaft.

So, you can physically put a 2.3 input shaft into a 5.0 T-5 (19t gear is smaller than 24t), but the teeth won't really engage (and the 1st time you drove it hard it would wipe the teeth off. The converse doesn't work: 23t gear of 5.0 T5 is too large.

This because 2.3l has ratios of 3.97/2.34/1.46/1.00/.79 for 1st-5th gears, while '91 5.0 has 3.35/1.99/1.33/1.00/0.68

Actually, there are 2 different 5th ratios for the 2.3l as both the counter shaft and output slide on, so you can have some interesting OD combinations.

There are at least 7 different main cases (Chev(3)/Ford(2)/Jeep/Nissan) and a dozen output housings (2wd/4wd/rotated/forward-mid-aft shifter/etc). But the gears (mostly) interchange between cases (just keep each set all together)*.

And don't blame me if they don't.

Hopefully, this helps. If not try this: http://www.allfordmustangs.com/Detailed/349.shtml

Thanks but I was just wondering if I took a ford 5.0 tranny and removed the input shaft could I install an input shaft from a 2.3 and have it work without any other mods.I watched a video on utube and it looked like it was really easy to remove it. Thanks for the answer. I have done a little research and the chevy's will not work with a ford. They are mounted on an angle.

If you want to use a 5.0 trans on a 2.3 in a RANGER???

The Bellhousing you want is the one off of an 88-89 thunderbird turbocoupe

ONLY these TWO years work, because only these two years used a hydraulic clutch
(All earlier Turbocoupes used cable clutches like mustangs.

Correction: 1987-88 only. 1989 was the first year for the newer body style, no such thing as an 89 TC.

No, different gear ratios. What most do when they are in that situation is either A: run the aftermarket adapter pilot bushing (its an actual bronze bushing unlike the normal roller bearing one) or B: have the v8 input shaft machined down to 4cyl specs.


If you were closer to NY I'd trade you my spare 4cyl box for your v8 box haha.
