Jeep T5 trans in the torquetube

I've got a lend of an adpter plate to suit Y-Block to Packard, and it is thicker than the one required to suit Chev to Packard, so I thought all ford and GM input shafts would be different lengths.

On second thoughts about this - why would they make different shaft lengths, when you find Camaros with ford bolt pattern T5's in them from the factory???

Is not easy trying to figure out things from the other side of the world!!!

 

Looks like crazydaddyo's Jeep T5 to Ford torquetube adapter can be used with a number of automatic transmissions, also.

Did some looking on the Jeep web sites and found that the T5 used the Dana 300 transfer case, so I assume crazydaddyo's adapter has the same bolt pattern on its front (trans end) as the Dana 300.

Turns out that that Novak (and maybe other Jeep adapter specialists) have adapters / parts to allow the TH 350, the later 4L60-E, the Chrysler 904, and a couple other automatic transmissions to bolt to the Dana 300.

So the way I figure, crazydadyo's adapter, a few other parts and you could run a automatic trans and keep the closed drive / torquetube rear axle in your early Ford.

That is all i think I know.

I don't have input shaft lengths here at my disposal, but believe the GM & Ford (common input shaft lengths as both have some oddballs) are close - probably close enough you can make it work with either minor trimming of the pilot snout or a "proud" pilot bushing...

 

Thanks Ernie.

I wonder if the holes to locate the bearing cover in the bellhousings the same.

 

Which bearing cover??

 

If you are talking about the front main shaft bearing retainer on the trans (Snout), then yes the Ford and GM NWC T-5 are the same.

 

Piper,
Yes, the tranfer case mounting for the manual and automatic are the same. I have not cheked the spline though. I believe the S-10 4wd automatic is the same as the S-10 T-5 as well.
Thanks for pointing that out. I forgot about that.

 

The main shaft bearing retainer (aka snout), as described by CDO

 

It should be - it has to mate to the same transfer case (Dana 300) & it wouldn't be very cost effective to have different input gears for the x-fer case based on manual/auto, but you never know (that's why I said "should be" )

 

http://i104.photobucket.com/albums/m177/49Cosmo/Threegeninputshaft.jpg Check out this T-5 hybrid next to a regular 3 speed Saginaw and an overdrive Muncie. I say hybrid cause I carefully turned the shaft and got a 2.95 estimation 1st gear and a .63 overdrive. This is backed up by the green/white bar code sticker.

This makes it a '88 Camaro front with a S-10 rear that puts the shifter in the middle of my AD floor. Notice the input shafts are the same length (only separated by 20-25 years), collars are the same diameter, shafts a different spline. Same bolt patterns for mating up to an engine that's 30+years older. Here's the proof that GM guys need to shorten their driveshafts http://i104.photobucket.com/albums/m177/49Cosmo/Threegenlengthdiff.jpg

 

Thanks for the Pictures Cosmo. That Helps us with the front end. The tail shaft that you are showing is for an open drive line and we have been discussing closed drive lines.

 

I've had some conversations with different people in the past week and There might be some confusion about which trans is which.

The first three photos are Jeep T-5










These next 3 are S-10 4x4. This example is in a Model "A" frame with a 40's V-8 drive line. S-10 adapter will not have provisions for mounting the rear trans mount. You should use the provisions on the trans for the rear trans mount.




Please PM me if you have any questions.

 

Good news, I spoke with the patern maker today. He said that the patern for the S-10 adapter should be ready next week and I should get about 10 castings in the next few week to start setting up my machining procedure.

 

Good news for the Model-A guys - now get cracking on the V8 version for the Jeep!

I'm going to send another email your way...

 

Ernie,
This first one will work with the V-8 too. This first one is for the S-10 FWD trans. The next will be for the Jeep.

 

Cool!!

 

Crazydaddyo put me down for a S10 one. Here is my TT its going to have to be shorterned a bunch

 

2.5 hours at the Pullapart covered in shit and 60 bucks later and I got me a filthy transmission. S10 4x4
You can see the F1 front transmission case poking out from the whippet cowl. Just need the flap plate adapter and I am good to go!

 

Good Score!!!!! See guys, You don't have to speend a bunch of money for this. Clean it up, flush it out ant it should be good to go. If you want that extra piece of mind that goes with a fresh trans, You can buy a rebuild kit for under $100. Simple trans to go through. Kit comes with all of the bearings, neadles, seals, and blocker rings (syncros) needed. Bingo......new trans for under $200

 

Not a hard thing to do. And from the looks of it You won't have to shorten your radius rod. I shortened my TT and drive shaft, but if you are worried about screwing it up or you don't have the means to do it yourself, any good driveshaft shop can do it.

 

Ok, so please give me some advice here. I am working my 39 deluxe coupe. Its got a '37 21 stud and a side shift tranny. I had written off the t-5 angle once because I have a 46 columbia. Could this work for me with out allot of hassle? I do like the idea of having syncro's, course I like the idea of having a/c too, but I don't think thats going to happen. What say Ye Crazy-D? and how much shaving is there?

 

How far are you into the build? Is the body off? Do you plan on using the Columbia with the 5 speed? Can you post some picture?

 

Jeep also made a T4 that is simply a 4-spd tranny - same physical size as the Jeep T5, so you could use that & your Columbia together I suppose....modern trans & classic overdrive....

 

so daddyo i've kinda been looking, and that cj t-5 is from 80 to 86 roughly. what is the 5spd in the xj's(cherrokee) or does that mate to the 300 t-case?

(edit ok i found the 30 diffrent trans' but sitll wondering if they have the same t-case patern. it looks like it and maybe the same inpunt patern?)

 

I sent ya an email with some pictures Crazy D. Yeah This build will be a tribute to my dad, and thats one of the things he specifically wanted was the columbia. I dont remember what year the trans is, but I'm thinking its older than the 21 stud. Its a 37 I believe, and it has a 46 rear end with the 9-34 gear. It is frame off right now in all its original glory.

 

I wish!
Input gear is broken and other problems I took it to a transmission place (I dont do transmissions) and it needs $1000 of work and parts oh well hopefully its going to be worth it.

 

That a shame. I've seen rebuilt units on Egay for $875.

I'm not a trans guy either. But I enjoy tearing things apart. I bought a S-10 2wd trans that was in good shape and transfered all of the guts from it and put them in the 4wd case. The trans is very simple inside and if you go to the Tremec web site the rebuild manual is there and can be down loaded. It has complete instructions about how to dis-assemble and re-assemble the T-5.

 

Check the tech link in my sig - there's not only a link to the actual manual (avail on Tremec site as mentioned above), but also an extremely well done pictorial rebuild. It is a dead simple tranny to rebuild - I like to set my end clearance on the tight side, otherwise, follow the manual.

 

Heres what I'm working with Crazy D

Ok collecting parts my adapter came from Dwight Bond the transmission has been rebuilt and I cleaned up the bellhousing and hogshead.
