I've never rated the shift quality of my T5 over a nice fresh single rail, I reckon the latter is a very underrated box.
 
If they'd developed and made them, I would take a 5-speed version of a SR over a T5 any day of the week. T5 gears have too much helical angle in my opinion, more like 30 degrees compared to SRs which are easily half that. This is why SRs are a bit more whiney. More helical cut causes more end thrust. This is the main reason why non-WC boxes are considered weak: they only have plain thrust bearings on the layshaft, not tapered like WC has.
 
Clutch diameter can affect shift baulkiness too. If there's a greater amount of clutch mass, the syncros have to work harder to speed up/slow down the whole lot to enable synchronisation.

Here’s a story I wasn’t going to share, but it’s Friday night so what the hell..

I had a T5 which I brought new from a certain well known Tremec Gearbox supplier in Warwick QLD, it was for my 32 Ford Roadster. The new box cost me thousands $$$$$

To be honest, it was one of the worst boxes I’ve ever owned.

Everyone raves about them?
Phk me, what a piece of junk.

Went through about 4 of his crap internal hydraulic slave cylinders, that no matter what , just kept on leaking. So gearbox in out x5 to fit all them. The only lasted a few months and started to leak. Yes they were set up correctly.

Oil leaks at the speedo drive which was oil from the gearbox leaking internally into the speedo drive unit. Replaced that unit didn’t fix it.new one kept leaking no matter what.

The box came with one of his “short shift” gear selector housing.

Nothing short about the throw of the stick that I could see, it was long stick throw like a old bedford bus.

Also you couldn’t slam the box through the gears when you were frying the tyres. You felt every tooth on every synchro.

And backed up on top of all that the worst ever customer service in history from the supplier.

So anyway....

this is only my second ever T5 I’ve owned, this one cost me almost nothing.

This one brought it out of a wrecked sh$t old XF ute that had been driven around the clock about 10 times , doing the Wagga mail run and taken more hits than Mike Tyson.

I drove the ute to test the box, it was smooth and good!!!!

So we’ll see how it goes, I’d suspect a whole lot better!

Anyway I thought I’d share my only T5 experience and tears
from a few years ago.

Haha

Anyway back to my beer

Cheers

if that bloke has a Wood in his name, then he's the one that FIXED BGDAV's issue on his T56 that DELLOW FUCKED becuase of a bad bell housing casting.. (suggest you don't use a dellow bell housing)
 
i think oil into the speedo housing is normal, leaking out of the cable is possible if it was a cable set up and not seating well. 
 
i had a CRS bell housing from Castlemaine Rod Shop for the T5 to 6cyl XE i had,  and also used a CRS bell housing for W58 supra box onto lexus V8 in XE also. (but this was supplied by Bullet Super Cars in Qld with their clutch and flywheel kit and checked for center/alignment as there were complaints of the odd one not perfect at the time)
 
T5s are pretty agricultural, even more so if the clutch isn't releasing enough, and even more again if changing gears at high revs. 
if i had My time over doing the lexus into falcon again, i'd use a T5 for less mods..(factory tailshaft, cross member, speedo, for starters, possibly clutch set up also.. AU one in this instance due to where the shifter would have come out due to engine position)

from what i know, and remember, the WC ones (or at least EB series 2 onwards have it)

If they have syncro on reverse, mine's fucked. Crunchy like a fresh bowl of coco pops

would need @SPArKy_Dave to date code it.  supposedly the WC has syncro on reverse?  

Mine came out of an EA and it is definitely WC. XFs have exactly the same ratios so I just assumed that they were the same box.

Yep seeing the layshaft end plug will need removal of bell housing. You could possibly go off the numbers on the casing but I'm not sure if the casings differ between them.

I have that exact box behind a pretty torquey 302, haven't popped it yet



4.1 never came with the pretend 5 speed. Yours will be a T5 100%. I have read that Falcons only ever got World Class T5s, never non-WC. The way to tell if it's WC or non-WC is if the front layshaft bearing plug is either an inverted Welch plug (slightly domed), or a machined plug with a dimple in the middle (actually a blanked tapered bearing cup). I am pretty sure that you'll have a WC box. I wouldn't put a non-WC box behind anything bigger than a 4 cylinder

T5 Reverse under 5th, correct . its the good one

sigma type, is Reverse next to 1st. i've had one, it didn't die with My driving back in the day on a 250.. can't be that bad(didn't have the car for that long though)
 

XE had that sigma box also ., but the T5 was available in XF, probably from 1987?  

For reference, an easy way to tell the difference between the 3.3 5sp and the T5 is reverse location, T5 has reverse under 5th whereas the weak 5sp has it next to 1st.

Boxes also look quite different externally.

it will be fine, they are fairly strong.. they break if they are worn out and you thrash em though.. 

The vehicle the box is coming from is a 1990 XF Ford Nissan Ute , carby crossflow 4.1.

It’s going into a XY wagon ,
bog stock Log6,

I figured it should be ok?

I don’t drive it like a WRX
or Ken Block.

V8 T5 box is much more rare/expensive than a 6cyl one though..  
 
i did see a transit van once with a commodore V8 T5 adapted .. wondered if this was the reason also.. or if it was a commo V6 one.. shifter location is spot on for the XF to EL 6cyl T5, is another to consider. and cross member issues potential etc

XF series 2 4.1 was available with the proper T5. Same ratios as EA, quite possibly exactly the same box.

XF 5spd ain’t much chop, came with the 3.3, from memory same as a sigma. Better off with a 4 Spd. Hunt up a e-series 6 cylinder. This is a bell housing I modded a singlerail bel housing the bottom two are the new

The Mustang and E series V8 T5s have a 5/8" longer input shaft which suits such an adaptor but they aren't cheap either. The bastards know the troubles you can have trying to adapt the boxes to these older engines so no matter what option you choose, it won't be cheap. The other problem using that type of box is shifter location. Might not make too much difference but worth researching first. I resorted to some serious DIY on mine to fit an EA 6 cyl one and 6 years on, still going strong.

Maybe ! Good thinking.

I think the v8 T5 has that longer input shaft. I’m not sure of the cost of that.

CRS have that adapter at half the price of a bell housing.

Anyways thanks

Haven't done this at all, but, could you make an adapter plate.? Like a sandwich plate, 20mm thick, and then get a longer input shaft.?  Just thinking out loud.

I know for my V8 I had to start with an old mechanical clutch toploader bell and mod that to take the T5. The single rail bell I already had (hydraulic type) had the same problem you saw with the lower bolt holes of the T5 sitting way below where the mounting face ends.

If you can find a 250 hydraulic single rail housing, that might fit. Some single rail and 3 speed housings have enough mounting face on the bottom to line up with the T5.

I had to turn the input bearing retainer on my T5 down by about 1.5mm to fit the locating hole in the bell.

would depend if the T5 tailshaft is from a sedan or (longer wheel base such as wagon, ute/van) 

the CRS one is a lot easier,
i did buy one back when Rod Hadfield was running the shop, the one i used could have either a hydraulic clutch on the left ,or the cable on the right side(leaded cars side.. )  assume this is the same bell they'd still have.
not sure if you would need the tail shaft cut down, i do recall XY having a different length auto than the later ones, but you might be able to measure it and for eg, use an XF sedan tailshaft in your wagon.. just depends on length difference, and budget of coarse.
 

if i can find my photo, i drilled 2 new holes in the T5 and bell housing higher up
