I got boned on a t5 off ebay was saposedly a V8 but it turned out to be V6. So i am wondering what internals are interchangable between different T5's. I was thinking of getting the guts out of amustang T5, or a 94 and newer Fbody V6 t5 and swapping them with mine, but i am not sure if the inputs are the correct legnth and if the guts would even fit the case. Aslo i have found a V8 t5 locally but the input, input retainer, top cover, and shift forks are missing would it be possible to use that tranny, with the top cover, shift forks and input retainer out of mine, and just get a new input? On the 94 and newer V6 T5's i noticed they used completely different speedos so i was figuring on reuseing the output from my T5. If any one has any insight i could really use some help thanks.

 

not sure where you are located, but ill be pulling the engine and trans from my TA in a lil while... stock 305 T-5 as far as i know, it has handled my 350 no problem...

 

I'm located in SC midway between Charlotte and Atlanta. How much would you want for it?

 

There's your best option right there. Just get the correct trans instead of trying to swap a bunch of different parts. Then throw the V6 trans on ebay and try to recoup some of your money. I know it sucks, alot of people get screwed by getting sold a V6 T5, but the easiest, most painless way outta this mess is to get the right trans.

 

I know that would be easiest but I have been unable to locate a good T5 for less than $400, and after shipping it would cost me $500. Which is why i was hopeing that i could get the local one that was just missing a few parts. Then just guy the input shaft and swap some of the case parts off of the V6 one. I was trying to see if anyone knows what parts are interchangeable in the different T5 trannys.

 

Here's how to turn a 6-cyl trans into a V8 one, in 1 easy step:


1. Buy V8 trans


OK, now you've got a V8 trans.


Now, here's how to change a 6-cyl trans into a V8 trans, in a few more steps:


1. Buy V8 trans

2. Buy rebuild kit (bearings, selective fit snap washers, seals, etc.)
3. Take both transmissions apart
4. Put all the V8 guts into the case that came with the 6-cyl trans, using the new soft parts in the kit
5. Sell or throw away all the 6-cyl guts and the case that came with the V8 trans


Now: if you can explain to yourself in terms that you are satisfied with, how steps 2 - 5 add value, then go ahead and do it.


Like Pat said, you basically got boned by buying a 6-cyl trans. That was a mistake, pure and simple, however hard it may be to admit it and however "expensive" the right trans may appear. That 6-cyl trans is WORTHLESS TO YOU, no matter how much cheaper it was than the right one. Forget about that, and move on. You need to find the right transmission in order to have the right transmission (duh). There's not really any shortcuts to it. That 6-cyl transmission doesn't get you any closer to the goal of a V8 transmission. Sorry if it's not what you want to hear, but it's the way it is.

 

I get the idea but like I said I can get a V8 tranny minus input shaft, top cover and shift forks for cheap. If I get that and a new input can I use the top cover and shift forks out of the V6?

 

Yes that would be physically possible; execpt that the countergear in this hypothetical V8 transmission might also not be any good. In fact, if the clutch gear (the part you're calling the "input shaft") is/was bad, then so is the countergear; and you'll have to buy a new one of those too, because they're also different between the 6-cyl and V8 versions.

You'll also need the "kit".

By the time you do all that, you'll have as much money tied up in it, or more likely MORE, than if you just buy a working V8 transmission. Except, you won't know whether it works or not, unless you have experience building manual transmissions (I'm guessing you don't, or you wouldn't be asking all this?).

Meaning, you're still money behind, and taking more risk.

The cheapest, safest, most correct alternative still remains, to just accept that the whole 6-cyl transmission rip-off was a left turn down a dirt road into the weeds; quit worrying about it; and just do the right thing.

 

The guy who has it had removed it from one of his cars because something was wrong with it, he can't rember what, so he tore it down, and lost some of the parts. I've already inspected the counter shaft and remianing gears the're all there and are in good shape. I figure i can get the tranny for around $50, a rebuild kit for $100, and an input shaft for $100, and have an working tranny for $250. the cheapest i've seen a working V8 T5 go for on ebay lately is $300-$400 plus shipping. i've rebuilt a couple trannies in the past i'm just asking to see what parts are interchangeable.

 

Pretty much every part is interchangeable other than the main drive gears, so as long as you get all the V8 gears, you should have what you need. I'd make sure to get the 5th gear stuff too since some of the V6 ones had screwy ratios for 5th gear too.

 

Thanks Pat

 

id also like to know what the difference is in the two trannies(v6/v8)?
arent they both the same thing or are the gears different?

 

It's just like you said. The case, tailshaft, shift forks, top cover, shifter, pretty much everything is the same except the gears. The V8 has a 26 spline input, whereas the V6 is 14 spline, and the ratios are very different. Most V8 T5's have a 2.95:1 1st gear while some of the V6 T5's have a 4.03:1 1st gear. The 6 cylinder trannys have steeper gears to make up for the lack of torque. Thirdgens are a pretty heavy car for a 6 cylinder to get moving.

 

ok so wouldn't this still be a nice trans to use because of the higher first gear? then again, does anyone have the gear ratios off hand by chance? ill take a look and see what i can find. because i also have a v6 trans swap that i got in a trade for a spare honda motor i had. just curious but can i still use the trans temporarily until i can get like a t56 or a munchie 4+1?

 

You can but you will need a special clutch disc for the 1" 14spline input on the V6 tranny ($120 at summit) also the tail shaft has different mounts for the torque arm. Other than those two thing she'll bolt right up, if it will hold together is anoter question though.

 

yeah thats the other thing. itll be on a modded 350 so i think ill just stick with my th350 until i can actually get a hold of a t5/56 or a muchie. im not so mad about trading half a motor that i couldnt even use in my honda for it though. anyone have a v8 tranny they will trade? lol......

 

Alright i've decieded to say screw and go for a T56! Anyone need a V6 t5, T5 bellhousing w/ shift fork, Hurst T5 shifter, T5 VSS, or T5 (V6 or V8) torque arm mounts?

 

v6 t5 is holding up 4 me after 6moths and i got a 305 with a cam.

 

^^^
is this under normal driving conditions? just from point a to point b? if so thats all im looking for really. i just prefer a stick rather than a auto(also the girlfriend cant drive a manual), just to add to insult so she cant drive the car. have or do you take your car on the highway at all, and what is your rpms around 50-70 mph? thanks if ya help me on that one.

~~~***nevermind another thread just answered my question***~~~

 

does anyone run the steeper v6 gears in their v8 t5? also what is the 5th gear gear ration in a v6 t5?

i also would like to know the rpms with a t5 at about 70-80mph with like a 3.42 or 3.45 gear in the rear?

 

^^^^
lovin' your iroc man!!! especially with those chevy rallies like i have on my TA in my sig. they would look much better with the beauty rings though. there is also a post in this section about what you had asked about rpms on the highway which i found(2000 seems to be accurate).

 

Here's a great chart with all the different thirdgen T-5 ratios, model #'s, etc. http://www.thirdgen.org/techboard/tr...ion-cross.html

 

82TransAM_45= hey man thanks alot! ya the rallys looked suprisingly good on my car with the fatty tire out back but the only reason they were on there was b/c i busted my tire on the irocs... btw i have a extra set of beauty rings lmk if you want em?

Pat Hall= thanks for the info man

 

no i have the beauty rings. that pic was with them off. that pic is from like 4 months ago. right now i hae steelies with 215/70r15 for winter. does pretty good for a winter beater too.
