The new 6 speed auto trans has its own separate computer and harness, whereas the C5 the PCM controls the trans functions as well as the engine. From what I've been told it would be a nightmare and many dollars to make it happen. There may be fitment issues also in mating to the C5 driveline. I'll sit back and wait to see what happens.

 

Any updates on this Nick?

 

Nick is off on a cruise at the moment (the kind on a boat...in the ocean) Im sure he'll be back on the board when he gets back

 

I'm keeping my eyes on this as well.

I think the key will be once an Alpha controller is all in and functioning, then guys like RPM will get it to live thru 1200HP, then as Nick has said.

Build it and they will come!!!!!!!!!

from what i was told that "they" are working on a "universal" trans controller..... as far as 6l80e still wasnt available last time i callled gean@fred beans. i have late model vette yard looking for trans, diff, torq, tube.

 

This Six Speed trans sounds like the way to go. I'm sure it will be released eventually just like the LS7 engine.

 

Hello guys, don't mean to butt in on you, but I thought you might find this useful. I've been watching the 6L80E closely for another application. I may be wrong on some of this information, this is simply what I have been able to obtain thus far.

A friend of mine can get the 6L80E, if I remember right the price was $1,800, but you'd need the bellhousing (or whatever they may call it in this application) to fit it to the rear. That also doesn't include the TC or the *ouch* $1,000 core charge. Prices may have come down since I looked at that. At the time she looked it up, it didn't even have a part number and they were making them about as fast as they were being put in cars. If she ordered one, it was coming straight off the assembly line.

Also, as near as I understand it, you need NO computer to run it, it's all internal. You might have to give it some inputs, such as RPM, but the only real connection on it is diagnostic. You might be able to reprogram it for shift points, but that's unknown as far as I know of. The best bet is to hope the shift point on this one matches the one you need. I believe the C6 is at 6,500, and it varies by the application. I believe the Yukon has the shift point at 5,500. Since they are modular, basically any 6L80E, as long as it's an 80 series, should work should you need a different shift point.

Another problem is the torque capacity. While it's fine for a mostly stock car, modified could be a problem. The only real difference between the 6L80 and the 6L90 is the number of clutches, the other being programming. They do share the same case. So if you needed more torque capacity, you can buy a rebuild kit and use the clutches out of it. Unfortunately, this has its limit, but I've been assured that there is an aftermarket kit coming, but when is up in the wind.

Anyway, the morale of this story is...if you want the 6L80, you can get it and you might need a different driveshaft and you might have to play with the wiring a little. You also might need a different bellhousing. Other than that, it's about the size of the 4L80E, so it should work just fine for you guys. If you need a little more capacity, you can get that also. I have no idea on the shifter though, but you should be able to get one out of a C6 and wire it up. The paddle shifters would be gone, but you could wire up buttons, or use the shifter out of one of the Caddies that use a slap-stick shift method. The shifter and the driveshaft will be the hardest part of the install as far as I can tell, although there could be some issues with the stock ECM being upset that it's missing something, but that could probably be programmed out. When you shift more, torque management hurts more, so remember that.

Hope that helps you guys, I'm in a different situation with the tranny so I have to wait until the aftermarket rebuild comes out.

thats hot!

 

Wow, I have seen the Ohio Boys driving their turbo cars to the track running 8's and then driving home on the 4l80E. Anyone dare to ask how much for the setup yet. I'll start the biding @ $4,500.00 without the diff but but I'm shooting to low.

mike i think your way off!

BTW

new 6l80e will be 1800 then the torque tube 850 then the diff is 2100
then the stall....... then beefin' up the 6l80e
oh yeah the tcu......when it comes out

 

just got off the phone w/mike @ yank....oh no!!!!! i want one!

 

But you just have to go through a couple of Rodney or SLP 4l60e's to make it more than worthwhile.

I'm all over this when the hardened race version comes out from Rodney

 

What was the price Nick????

It looks very nice!

 

 

I say give it up Nick

 

I'm still confused as to why you think one is required. According to all of my information, it's internally controlled, even the lateral g-force sensors are within the unit.

Aside from changing shift points or diagnostics, that is.

 

Interesting .
