Can a 3800 T-5 be MADE to work on an LT1?

I searched for awhile.

Say this REALLY needs to happen.

Custom clutch can be built. All the stock 3800 clutch "stuff" can be used. Custom flywheel built.

Will the 3800 T-5 BOLT TO an LT1. WHY?


Thanks

no bolt pat diff

cause there was some v6ers wnating a T56 in there 3800

yep what he said.

anyways isn't the T5 only rated to like 300 ft lbs. of torquel that is why it was never put on anything bigger then a 3.8L, 4.3L or 305?

all 3rd gen 350s were auto only, and vettes had 4+3 trannies or T56s.

It might bolt up, but it wont hold up.

Yeah Bell Housing Problem. I guess you guys arent familiar with the 2.8 L T-5's in the 80s using that ford bell housing.

So an LT1 era 3800V6 T-5 WILL bolt onto an LT1.

Is there an input shaft issue, or do those rumors stem from the 3400V6 tranny.

I know the 3400 T-5's have different input shafts from the regular V8-T-5'S from the 3rd gens. So maybe this is why people think the input shaft is different.


Anyone have a 3800 V6 T-5 W/bellhousing attached, that they can measure the input shaft on?


Thanks for all the help guys!!

Wont work out real well, you would need adaptors and what not to make it work. Recall they do bolt up to 2 totally different engine configurations, LT1 is 90 degree, and the 3.8 is 60 degree.

I thought that the 3400 was 60 degree and the 3800 90 degree.

I will double check that later on tonight. But reguardless of degrees it wont bolt up nor hold up.

3.8L is 90 degree, 3.4L is 60 degree

thats right...


fitment issues or not, you put a t5 to a lt1 the torque is going to die realy quick 2-3 t5s with custom adapter plates is more expnesive then a T-56 swap

I wouldn't expect it to hold up real well. And I planned on yearly rebuilds.

But the stock 3800 clutch setup would be easier to adapt to a 2 or 3 disk 5.5" or 7.25" Tilton clutch.
Plus the trans has to be lighter and 1st and 2nd gearing is MUCH better.
Plus the initial cost would be lower than a T56

But if it won't bolt up it won't do me any good.

weekly rebuilds sounds more realistic... don't bother. its like putting plastic wheels on a locomotive.

but technicly any transmission can be made to fit to any engine (provided the input shaft is proper). all you have to do is get a custom forged bellhousing and you're set! of course, you'd have to really want to throw your money down the drain really bad to do something like that.

well it looks like others got back to the 60 vs 90 question first.
It definatly wont hold up, it couldnt handle the torque of the 5.7 in 3rd gens, it definatly wont handle LT1 Torque.
