Im not condoning the use of a T5 behind one, but the question does come up frequently

To use it you need:
BBC bellhousing PN 3899621
LS1 style clutch
Adapt a VSS of your choice. This build used a 40 tooth 4L60E reluctor and S10 4WD VSS via brass adapter fitting from lowes

Happy motoring

 

Great to know! This information does come in handy when you have an aftermarket T56 that is bolted to your T5 bellhousing and you are now about to do a LSx swap. Only question is if the bellhousing can handle the same (or near the same) amount of horsepower... searching now.

 

I thought about this as I was going to do it but wont the 621 rotate the transmission into the 3rd gen wrong? Don't the 3rd gen bells rotate it like 30 degrees towards the driver? I wasn't sure of the implications of that

 

I do know there was a rotation issue for the t56 to the t5 BH, but I had an adapter plate to straighten it out. But now that I think about it I am guessing you are asking if the t5 would be rotated wrong...

 

Im not trying to start a war or flame fest here but anyone whos going through the effort of doing an LS swap would be VERY wise to avoid the T5 imo. Ive roasted a couple T5's with stock engines in the early 90's and they are not upgradeable. Unless you want to drive like a old granny ( in which case I see no reason to swap to a more powerful engine anyways )

If you want a cheaper/newer/stronger 5 spd try the truck NV3500 its about the same size as a T5 and came on a lot of gm trucks and even some LS powered trucks so the bell/flywheels/clutches are MUCH easier to come by, and they are considerably stronger than the T5

Of course t56 is the best way to fly imo but they are damn pricey

 

I only considered it because I have a complete T5 setup in my basement

 

Just go easy on third gear if you run it as in rollllll it on and shift slow. Do that for third? and just maybe it'll survive. At least thats how I see it

Good luck whichever route you go

 

I agree with you to some extent, but on the other hand, I'm starting to see a bunch of stock 5.3 style swaps popping up, and I think a T5 will do ok in that environment if it's treated right. Chances are, if somebody is doing a stock 5.3 swap in the first place, it's probably a budget oriented swap, and in that situation the T5 can play a roll, although it should still be considered a temporary option with the intent to upgrade the trans at the earliest possible convenience.

 

4.8's. A nice, low-torque, economy-oriented engine...

 

If one happens to do a ls swap, and happens to have a T5 setup to use, I personally would find it wise, and cheaper in the long run to sell the t5 swap to help fund the t56. T5 swap reasonably bring 450-500 ( atleast here), and a t56 swap can usually be had in the 1200 range ( again, atleast near me). Rather than break a t5 and wast a 500 dollar swap, to go buy a 1200 t56 swap, it makes more sense to me to sell the t5 before it gets broken and atleast you get that 500 or so instead of throwing it away. I have broken 2 WC T5s with stock 100k mile plus TBI 350s.... And we all know the 5.3s can run circles around those too.

 

what if you already had a TKO or other T5 based performance trans, you have something that IIRC bolts in place of a T5, and will take abuse all day.

 

Jumping on a really old post here...

I've seen a thread that said a new hydraulic throwout bearing was needed to run a LSx in front of a T5.
Can anyone confirm that?

It is not required

A fork style external slave can still operate the clutch, but you run into exhaust clearance issues with LS
OEM SBC ran the exhaust under the oil pan towards the PS side
LS, the oil pan takes that space so you have to go rearwards past the trans. Thats where the slave cyl is mounted

Use a 4th gen T5 bearing retainer to get the internal HTOB mount on a budget

 

Maybe the T5 is actually an option now. I remember reading this article just as I started my lsx journey.

Here's the archived version if the article doesn't load. It didn't for me. It is quite old...

I remember the G-Force upgrade being too expensive, and there were threads that said the T5 was still too weak with the case upgrade., So I bought a used T56. Jegs is selling the G-Force case for $326.
