I'm putting a 1993 5.0 in my 55 truck. I found a t5 that I can get at a pretty good price but I have some questions. First is how do I tell if it's a 4 cyl or a v8 transmission? Also the transmission supposedly has a s10 truck back on it? I was told a normal t5 out of a car would put the shifter to far back to use in my truck? Does this sound right? Can the shifter part of the transmission be changed? Also if the transmission has a S10 truck back it I would imagine it would be a 4 cyl tranny? I am nowhere near knowledgable on this so any input would be greatly appreciated. Thanks

 

Well, you have potentially the worst of all worlds - a tranny that has been modified and you don't know what it started as.

The only way to tell what engine the T5 was originally behind is with the tag.

IF there is a tag still on it, it will have a number that has something like 1352-xxx. That 'xxx' tells us what the tag was on originally, and what the tranny is likely. However, it is also likely the tag is missing. If it's a late '80s GM T5, there is a possibility there is a green and white sticker on the top of the tranny with a barcode. There will also be a 1352-xxx number on this sticker...if it's still intact and legible. However, if the shifter has been changed, this may only be the top cover that went with the shifter and not anything inside the tranny.

Yes, it is possible to put an S10 tailshaft and shifter top onto another T5. This will likely affect the speedometer drive.

I think a T5 out of a car, might be usable in a truck depending on how you shape your shift lever and your seat configuration. It will likely be better with an S10 tailhousing/shifter.

If it is indeed an S10 T5, there is no way to know if it's from a 4-cyl or 6-cyl without the tag. Both of the S10 gearsets were available behind all engines.

Looking at it visually without opening it up and without the tag, you can look at the following areas:
Tailshaft shifter location: Forward shifter = S10, Rear shifter = car
Shifter box: rectangular = Mustang, Square = GM
Transmission case bolt pattern: narrow square-ish pattern = Ford, wide rectangular-ish pattern = GM
Input shaft: measure length, diameter, and count splines - many variations, but can narrow things down
Front of case countershaft bearing: solid one-piece (like freeze plug) = NWC, two-piece with 'shiny' narrow race ring and dark center 'plug' = WC

Other than that, without the tag, all you can do is open it and start counting teeth.

Bottom Line: Without the tag, it's a wildcard and unknown. I'd keep looking for a T5 with better history that can be validated.

 

Man thanks a lot!! That's a lot of info! I think I will keep looking. What would be a good 5 speed tranny to use in my truck behind the 5.0?

 

The T5 should work fine behind a 5.0. I have a Ford T5z (wc) behind a Ford 6.7 with no issues in my 48 F1.

Ford put the T5 behind the Mustang 5.0 from '83-95. But you want to stay away from '83-84 - they're NWC. The '85-88 were slightly weaker than the '89-95 due to a change in the alloy used in the gears. The '94-95 input shaft are almost 3/4" longer, so you have to use the corresponding bellhousing (or swap input shafts with an '89-93).

So...I'd be looking for an '89-93 T5, but wouldn't turn by nose up at an '85-88 if the price was right. You'll need the matching bellhousing, but be aware that Ford used a cable-type clutch. Most folks swap to hydraulic.

I've seen folks put these in the trucks w/o swapping the tailhousing. The shifter is right up against the seat, but some judicious bends in the shifter will have it clear. Alternatively, you can make or buy a remote shifter.

 

Ok let me ask a question. I looked at the tranny. The guy said it was a ford and it has the timpkin bearing and the torx head bolt so I'm gonna say it is a WC tranny. Now did the WC transmission come in 4 and 6 cylinder or is the WC always a v8?

 

^ I can't answer that for sure, I think if you can prove it is a WC then your good. In other words I don't think there is a light duty version of a WC that would be put in a 4cyl. Flaternie has offered you amazing info and can probably answer that for you for sure. But here is a link that may provide some more details for you to help ID it.T-5 Identification Without a TAG!

 

Yes, the WC was offered in some of the SVO 4-cyl cars. The input shaft will be long and skinny, but if you've never seen either, it's hard to compare or know what you're looking at.

The WC did come in 6-cyl too, but these are later 3.8 V6 used in Mustangs for the most part.

It's far more common to find the V8 WC that came in the Mustangs, than either of these.

Without the tag, you're stabbing in the dark.
