RPM VI T-56 or VII TR6060
 

Next year I plan on finally building my drivetrain. This may or may not seem a dumb question but I have an 06 Z06 and was trying to figure out if I should go built T56 or pay however much it is to convert and get a built TR6060.

Thanks

Depends on what you're doing. If you have plans on 900+ whp then go 6060; if not go T56

You should check out Tick Performance. Much cheaper than RPM and just as good.

I have a 2006 C6Z. I asked the same question about the T56 or TR6060. Many people warned that the "T56 shifts better, TR6060 is notchy". I wanted a performance 5th gear and that would have been difficult to achieve with the T56, so I went with an RPM Level VI TR6060 with C5Z gearing. I love the new trans, it shifts absolutely incredibly, no notchiness, just effortless shifts that make regular drivers into amazing drivers.

Don't overthink it like I did. Get the TR6060. You'll spend around $5k if you give them your core T56. Customer service is amazing. Call up Jeremy Jones and get a quote.

Did you stay with the factory gear ratio in the rear end?

is a tr6060 a bolt in?

More or less, you have to fab up something for cooling.

I have a T56 built built to level 5 and has a C6Z06 mainshaft and C5Z gears; shifts awesome and not notchy at all, no way you're missing a gear with the way it shifts.
Also has stage 3 C6Z diff.

I've heard that the 6060 doesn't shift as good but every one I've tried shifted fine. T56 is a little lighter so there may be some power gains there.

Are 5th and 6th paired together the way 1-4 are or are they individually selectable?

Pretty sure they are paired, like I got a .84 5th but they could only give me a .56 6th because of this, whereas I wanted the stock .50 6th.

interesting, .56 is a lot more useful as a 6th than .67 at least

I got the .80 5th and kept the stock 6th with my 6060

I've been swindled yet again.

.80/.50 sounds perfect, I'll have to look into that.

Lol. One day Josh...its gonna be payback time.

Gonna take the Miata for a drive after I take an upper decker :)

:rofl: There really should've been a sequel.

Yes! I thought it was a hilarious movie, especially Kristen Wiig's character, same haircut same vest.

When I took my C5 transmission apart, 5 and 6th are paired. They came out, one piece with two gears, one at either end.

Here is a T-56 pic I took off of ebay - couldn't get to my pics when I took my C5 trans apart:

They are paired. I have the same setup that Josh B used.
