No sure where to look on this site as there isnt a search option
But im looking at doing a T5 gearbox conversion to suit the 292..
Tried searching the net but can not find the exact answer im after.
- -OK so with the 292 i know that i can use the 3 Speed bell housing that i have already and mod it to suit. But what i need to know is can i use any pre 1993 T5 gearbox and replace the input shaft to the mustang 7 1/8( 180 mm) one.?
- -If i end up using a adapter plate wouldn't the input shaft need to be approx 19 mm longer anyway .?
- -Also do you have mix match the clutch and pressure plate ??

You can also link from the opening page here to John Mummert's site. Just scroll down a bit. He has an adaptor & other info on T-5 conversions..

Paul's suggestion of looking at the information on John Mummert's web site pertaining to the T-5 installation is a good one.
See if this will get you to it... http://www.ford-y-block.com/t5in-cars-bird.htm
Hope this helps.

To answer your questions, the input shaft should not need to be swapped, only trimmed.
You don't have to mix and match the clutch pressure plate but that is an option.

This is a picture of a292 and Z code (see 251 stamped on the trans) T5 (pre '94) mounted to a standard bell housing and a Modern Driveline adaptor. No trimming involved but two new holes need to be drilled in the Bell Housing. Some prefer the Mummert adapter, whic I understand requires some minor shortening of the input shaft. This apparently puts the clutch disk a little further on to the splines. A feature favoured by hard drivers.

Cheers for the help and the links....=D
It will be going in a 1929 ford tudor ,thou i will be using the bellhousing from the 3 speed gearbox thats on the motor now as i will need to use the original mounts for both font of engine and bellhousing ones
The main thing im still trying to work out is if this T5 gearbox which was from a VN commodore 1988-1991 will work or not
Or this one that is the V6 model

If you have mounts on the bellhousing, it is from a truck.
Pic here shows the truck ears.
http://www.ford-y-block.com/t5in-trucks.htm
You may be better off looking for a car bellhousing, all the Cussos in 55/56 here were manual
(i think).
I don't think a commode T5 will handle the torque of a Y.

By Reaper5054 - 10 Years Ago

yeh i have the bell housing with the ears/ gearbox mounts
was just looking at the gear ratios for the VN and the mustang one and they about the ratios ...so should be strong enough
|
|
By slick56 - 10 Years Ago

Although the ratios are the same, there are T5's and then there are T5's.
Here is a link to the ratios and torque specs for the different models.
I would suggest a minimum torque rating of 300 ft.lbs., the Y is a torquey engine.
http://moderndriveline.com/Technical_Bits/transmission_spec.htm
A bit more info (WC is World Class, more info here http://moderndriveline.com/Technical_Bits/t5_history.htm )
GM WC About this time (1990) GM entered the WC T-5 with the S-10 and Camaro T-5. Borg Warner produced both a 2x4 and 4x4 T-5 for the S-10 with different gear ratios depending on motor type. The 4x4 model was connected directly to the tranfer case with a short main shaft and tail shaft housing. GM used the T-5 in both the V6 and V8 Camaro’s, but the gear ratios were different, as well as, the bellhousing to transmission bolt pattern. The V8 Camaro received the same bolt pattern as earlier four speeds but with a 22 degree rotation to place the shifter closer to the driver. It is believed that GM changed the bolt pattern of the V6 T-5 so that it couldn’t be installed behind V8 motors. From looking at the outside of a Camaro T-5 it is difficult to tell them apart. GM used the WC T-5 2.95 gear set only in 92-93 IROC Z Camaro’s. In 1994 GM switched to the new T-56.
The bold is from me.
Good luck, post some pics and keep us informed of your progress

Cheers "slick56"...good info right there....
After days of researching the many ways in which i could of installed /modified the internals of a Vn T5....as finding a mustang T5 or even one that is not over the $2000 mark in Oz is a task...
I think i will just stick to the Standard 3 speed that came with the 292 out of a 1956 ford f100.
because the last thing i want to do is spend all that time and money on the T5 only for it to break under the torque of the 292...
But cheers for everyones help in info

Unless you are drag racing the T-5, it should live quite well behind a 292. I have the T-5Z behind a 351W +040, 3.750" stroke for 385ci, and it had been driven on the street for years, and raced occasionally with drag radials. I also have another stroker 351W +.030, 3.680" stroke and 14psi boost with "Z" trans that has gone as quick as 9.82 @ 141 mph in '88 GT with AC, PS, roll cage, etc. I have a daily driver 91 LX with "Z" that has been on the rollers with 293hp/303tq to wheels. The stock T-5s will not last long with abuse, but don't give up on the idea, since the newer upgrads will live quite well on the street if you do not use slicks. JMO, but I have driven the "Z" transmissions since 1988 in Fox mustangs. Broke axles, but not transmissions. Joe-JDC

Just to let everyone know, my WC T-5 out of an 89 Mustang has stood up surprisingly well behind my basically stock 292. This is also with a stock 10" clutch (which also survived quite well) considering how I drive my car! Everyone who knows me will tell you I drive my car like I stole it! I even snapped my 9" housing in two, but the clutch and tranny, no problem! I leave the line at about 3500 RPM on a clutch dump and shift it right up to 5500 RPM (I get rubber right into 3rd
!). 
It will be interesting to see how it holds up, now that I am building my Y with a Mummert Performance engine kit!!!!!

That's a shame, because I LOVE my T-5! Car comes out of the hole sideways due to that 3:35 to 1 first gear and I have gotten over 27 MPG in 5th due to the .64 overdrive!

Earlier in this thread I suggested you read the Modern Driveline article that delineates the development of the T-5 since 1980. The point of the article was that ALL T-5s are NOT the same in their design and construction. There have been engineering changes that make some T-5s better choices for putting behind a Ford y-block than others. While how you drive your vehicle is a factor, the torque output of a Ford y-block makes some T-5s a bad choice for reliability and service life. There's nothing wrong with sourcing a T-5 from a salvage yard, but you want to know what vehicle to take it out of...
Here's a piece of that Modern Driveline article...
The "Z" Spec T-5 In 1993 Ford started offering a new service unit to the Ford Motorsport crowd. The nick name T-5z comes from Ford’s part number, 7003Z. The T-5z is best described as a 1993 Mustang Cobra T-5 with 2.95 first gear set and .63 over drive. It has the best of everything. Hardened gears, short throw factory shifter, steel front bearing retainer, and tapered output shaft bearing and a seven tooth drive speedometer gear. Best of all it has a torque rating of 330ft/lbs. based on 100,000 mile usage. The stock T-5Z can handle up to 450hp with a soft locking clutch and is not shock loaded like in drag racing.
_______________________
Just as all FoMoCo 239, 256, 272, 292, and 312 y-blocks are not the same, not all Borg Warner and TREMEC T-5s are the same.

This is with a "World Class" T-5, which is found in Mustang GT's from 1987 to 1993 (this is what John Mummert recommends for his adapter). I was told NOT to use pre 87 Mustang models or ones from Camaro's or S-10's (these are far weaker models)! I have read up quite a bit on on my W.C. T-5 and found only a couple of negative things about them. First was that power shifting from second to third could damage (jam) the syncro's. This is corrected with a good shifter with stops (I use a B&M "Ripper" shifter, with a Hurst Stick). Secondly is the aluminum "slide" for the throw out bearing. This can wear and hang up the bearing. I haven't changed mine yet, but steel replacement ones are available.
As per post 93 T-5z, I am afraid I know nothing about them. Oh and by the way, not sure if I mentioned, I am using a stock, aftermarket, Ford 10" replacement clutch and was REALLY surprised when I pulled the motor that my clutch looked like new! (The clutch dump in my vid is common practice for me! LOL)
Good Luck my friend!

World Class does not mean anything in regards to strength. It was more of a creature comfort and usability upgrade. Weaker ones can be world class and stronger ones, up to the Z can be world class (the Z is world class). World class T5s came later in production and as the T5 aged, it tended to get stronger, so following that logic, you can say that a world class unit is generally stronger but it is not due to the world class designation. If you pick a T5 solely on the fact that it is a world class unit, you can pick one that is not technically suitable for your application possibly over a non world class unit that is. The world class T5s were not limited to Ford.
Ideally, you simply want a T5 from behind a V8. The reason Camaro T5s "don't work" is that the bolt pattern does not match the pattern on Ford transmission adapters. There may be other issues (input shaft?) that make it more difficult but a V8 Camaro T5 should work fine, if you can get it mounted. The 2 - 3 shift is a problem (not really a problem since it is not designed as a competition transmission; it works perfectly for its intended use) with any T5.
That said, Tim and Bill have 4 cyl T5s behind a pretty stout street and turbo charged engines, respectively, and so far there do not seem to be any issues for street driving. That is certainly not to say that there won't be problems, but they are working behind a V8.
T5's have tags, just like rear ends. That tag is the only way to positively identify what you have and determine if it is one that you want.
Regarding aftermarket shifters and their shift stops, see this for consideration:

Thanks for the info Charlie!!! That being said, my T-5 came out of an 89 Mustang,so technically it COULD be a T-5z??? I will have to check the tag when I get home. Will it have the "Z" designation on the tag?

Since the Z did not come around until 1993 and I don't believe it was factory installed in anything, it's not likely that a transmission from an '89 Mustang is a Z. If it has a 3.35 1st gear, like you said, then it definitely is not. The Z is 2.95. I'm looking at a picture of my transmission which is a Z and it looks like the tag has M-7003-Z on it. The picture is not of the tag and it's not clear. My tag is on one of the tail housing bolts, on the side where the speedo cable attaches. I've seen websites where you can decode the tags, just like you can with rear ends.
Here's a chart. Yours should be #169 if it is the original transmission for the '89.

Charlie where does the shifter come through the floor at on your truck? What shifter are you using? I have been told that the shifter will be about 8 inches in front of the bench seat and I would like to verify that number. I am about to place an order for a M-7003-Z transmission.

The shifter came out right at the edge of the seat. However, I am using bucket seats so the shifter position doesn't really matter for me. I started with the factory shifter. I'm using a Steeda Tri-ax now. The Steeda seems pretty good but since the Z comes with a shorter throw shifter, I didn't notice any improvement there. It does feel better but if I was to do it again, I wouldn't spend the money on an aftermarket shifter, at least not until I need to replace the factory one. This picture is with the factory shifter.

Thanks Charlie. It looks like it will work with the Lokar shifter (MSL6B2) I am going to use. It has a double bend which will move it away from my bench seat.

I used a B&M "Ripper" shifter in mine witch came with an "S" shaped, 2" offset for the stick (forward or back). I set it so it moved my stick 2" forward and installed a Hurst (for nostalgia look) curved stick which is perfect for a bench seat!
