Default 6 speed transmission on a 4.0?

Hey there,

Is there any 6 speed out there that would mate up to a 4.0 without a whole lot of experimental fabrication?

Would the "final drive ratio" be lower, increasing mpg's ?

You can mate a TR6060/T56 (these are both 6speed) onto a 4.6L and 4.0L engine; I believe the modular engines have a universal bell housing bolt pattern.

The only difference I could see is that you might have to order custom made crossmember, but I think there might be an aftermarket crossmember.
Or, I could totally be wrong and the stock crossmemeber will fit on a TR6060/T56 directly, since the TR3650 is also a Tremec.

That sounds great!

I plan on trading up to a GT within a year - and having a 6 speed would do wonders for my wallet. I might be able to get one for free since my uncle owns a scrap yard. Do you know any cars that have that transmission stock?

Thanks

You will need this for the TR6060 or the 3650.... I am about to get one for the 3650 I am getting Sunday.

Hold on!
The input shafts are different between those trannies and the stock POS T5.
So you need to have that 6spd altered.

I forgot who it was now, but in our V6 section someone did that swap successfully...

Yeah, NicePony did the swap. I think he's the one who made the conversion piece too.

Hello, wonder if you'd relay NicePony contact info on the 6 speed conversion? I rem'ber seeing something on this a year ago, but am now in need of a better trans-namely one that will actually shift when the throttle is under duress! Mine is a '07 V6 with the Xcharger supercharger kit, Auburn posi, a few other things. I've replaced one 5 spd under warranty & had the new one upgraded-it's still a 'real piece of work'! Thanks, Makadidle
