First off all why do that swap when you can get a tr-6060(new version of the t-56) that bolts directly to our cars without too much custom parts for 4k. Second of all the tko600 is only about 20 lbs lighter than a tr-6060.

^^^Most people don't know about the TR6060. Tremec's site is ancient and never updates the world about it's changes apparantly and a lot of people are too lazy to call and ask. But it is a good tranny. And yes, you're right, most people asssume the 6spd tranny's are heavy, but its only like a 20lb difference.

 

I still don't need or want two OD gears.

 

I like the idea of the 6 speed. I don't need it, but with 4.10 gears it would drop my cruising rpms about 10%. I'm not sure what the ratios are for our 5 speeds, but 6 speeds generally are closer in ratio, keeping your car in the power band longer.

Plus it's something different. If I really wanted a track queen, I would get a 3 speed auto with a transbrake. But I love rowing through the gears.

 

If I ever need to upgrade my trans after my blower install I am getting a 6 speed just for highway cruising. I am keeping the stock 3.55's in the rear but It would be nice to loaf along at 2000 rpms in 80 which is my normal cruise speed. I figure it would be worth a couple extra MPG as well.

 

When I talked to D&D, they said the 6th gear (now they are putting in the 6060 transmission) was 0.62, which is what our 5th gear is now. They said nobody makes a conversion to get the 0.5 gear (which I wanted for highway use) put in.

I thought it was .68?

 

Simon, some places list the 5th gear in the 3650 as 0.68, but more sources and people have told me that we have 0.62 as our stock overdrive gear.
