Re: T5 FAQ - Everything we know about the T5

Hey guys, I'm wondering if anyone can tell me the lenght of the 3rd gen T5 V8 bellhousing is?
(etc. the distance from where it bolts onto the engine and to the transmission it's self)

I'm merging a V6 4th gen bellhousing and a 350 auto transmission housing together so i can fit my WC T5 to my 350/383 engine.
The reason for the 350 housing is that i only have a 168 t. flywheel with the 400 weights and the customs here in Iceland from the states is ridiculous.

I appologize for my bad english, after all I'm from Iceland

Ps. it would be awesome if measurements would be in centimeters or millimeters

Re: T5 FAQ - Everything we know about the T5

Quick question, need answer ASAP...

Does the tail housing from a WC work in a NWC? For some reason I can get a WC cheaper on eBay than a NWC and I need one NOW...

Yeah, far as I know, there shouldn't be any difference on the tail housing between WC and NWC T-5's.

I know this reply is a bit late, but both the V6 and V8 input shafts should use the same pilot bearing.

If I remember correctly the counter shaft bearing pocket is different on the WC Tail and is not interchangeable

Re: T5 FAQ - Everything we know about the T5

The WC and NWC use different bearings on the counter shaft, so the tail housing is probably different.

Re: T5 FAQ - Everything we know about the T5

Old thread but I'm posting to clear up the WC verses NWC housing differences and can they be interchanged.

The difference is in the thrust surface for the counter shaft thrust bearing. They can't be swapped straight across.

The WC has a flat surface as in the first pic, and the NWC has a recess. I'm buying and selling S10 T5's now and have run up against this. The NWC tail can be modified by cutting the thrust surface deeper to work on a WC trans. I have done this because several customers have bought S10 NWC tail housings for me to modify to cable drive, but they have a WC trans and didn't know the difference in the two.

So bottom line when your buying a difference tail housing, make sure they match.

T-5 = manual, 700R4 = automatic.

Re: T5 FAQ - Everything we know about the T5

ok so everything I see on my trans says it's a w/c by the bearing being a Timken, the numbers on the tag being 1352-197, the stick on tag being 1352-197 yet on the shifter tower there is the numbers 13-52-066-923 and R5 and on the trans body in kinda script lettering Basic 2A..... what is up w/ that? I need to change out the oil to atf if it's a w/c it is in a 84 SE, so I would think originally it had the t5 and then it got changed out to the w/c ,,, and like I said being that I thought it was a t5 I put gear oil in it..... hmmmm. never did trust those tags in that anyone could stick one on and.... oh one other thing as I understand it the bearing is Timken for the w/c and not marked on the reg t5... correct me if I'm wrong here. replacing the clutch which the center of the clutch plate broke free from the friction surface outer.... never seen that before.... thanks for the excellent thread..... ok so how does one go about making about four hundred horse out of the 2.8... lol

Re: T5 FAQ - Everything we know about the T5

The 13-52-066-923 number just refers to the part # for the transmission case, that's all. Have no idea what R5 refers to, but yeah, going off the 1352-197 number, you've definitely got a WC T5 trans.

Re: T5 FAQ - Everything we know about the T5

I actually have a T5 behind a 79 camaro... hence why my username is 2.5 lol. But anyway, I'm tired of my mechanical linkage, would like to go hydraulic and I was curious to see if there were any years of T5 camaro that got a hydraulic clutch, and where it sat on the bellhousing.

Madias is correct, and to add to what he said the transmission sits at as I recall is a 17 degree slant to the left. The stock shifter is angled to compensate for this.

I have a couple of shifters I'll give you, and have a bell housing, but no clutch fork I'd sell.

Re: T5 FAQ - Everything we know about the T5

I have a 1984 Camaro V6 transmission that is like to consider changing the 5th gear on. Is there a reference out there for NWC tooth counts?

i have searched a lot with google and no success. Could be good to record that on here.

For the V6,
Input shaft gear - 21 teeth
front counter shaft gear - 37 teeth
5th countershaft gear - 53 teeth
5th mainshaft gear - 23 teeth

for the V8 with the .63 5th gear
Input shaft gear - 24 teeth
front counter shaft gear - 31 teeth
5th countershaft gear - 51 teeth
5th mainshaft gear - 25 teeth

for the V8 with the .73 5th gear
Input shaft gear - 24 teeth
front counter shaft gear - 31 teeth
5th countershaft gear - 55 teeth
5th mainshaft gear - 31 teeth

Re: T5 FAQ - Everything we know about the T5

Here is a an awesome rebuild video from Eric the Car Guy on complete teardown and rebuild of a T5 along with Paul Cangialosi from www.5speeds.com What's interesting to note is that Paul is the original inventor of the cluster support plate and he shows how the counter shaft wobbles on the stock plate and why he built it from Steel originally. There's also a little hack that he shows which is to grind flats on the revers shaft to make it shift better and he also points out the weakness in the shift fingers.

Check it out. Part 1 below.

Re: T5 FAQ - Everything we know about the T5

So I've got an odd one, I have a T-5 in a second gen Camaro, and I run a modified 2nd gen mechanical linkage to work with the T-5 mechanical fork, as the T-5 is probably out of an 83 camaro. (not sure on that one) I recently built a one piece rear main motor (vortec, to be specific) and I was sort of confused about which clutch to use. I will be running a flywheel for a 91 Camaro, to accomodate for the balance and difference in crank rears. I've been leaning towards grabbing a clutch for a 91 camaro as well, but I wasn't sure if that would work with the mechanical fork. Do you suppose the mechanical release would work just fine with a clutch for a hydraulic throwout?

Re: T5 FAQ - Everything we know about the T5

82-92 Camaros didnt come with hydraulic throwout bearings, 82 was a 4 spd cable clutch, 83 was a cable clutch t5, and 84 to 92 is hydraulic clutch pedal master and slave cylinders but thats it, as for your fork if itd the same diameter as the t5 one where it holds the throwout bearing than go with a clutch kit for an t5 V8 camaro, i like the centerforce stage 2 clutch myself.
