The new cars apparently have the ECM programing to handle the 6speeds, not sure about our older ones (OBDII might be more flexible). So say taking a 6L80E from the Vette and putting it into a LSx car, think that'd work? I'd love to put one in my LT1 car, but I'm quite sure the bellhousing won't bold up :\

Just figured I'd start a lil discussion

I've read that the 6L80E is pretty similar physically to the 4L60E. We've discussed this swap some on corvetteforum, but I haven't seen any installations.

I'm hoping somebody will take the plunge because I'd love to do that when my 4l60E fails. With the 6l80E and 2.59 gears I'd have the same first gear overall ratio I have now with 3.54s, while having the same top gear ratio I had with 2.59s.

Oh, but you'd want a 6L80E from something other than a vette. Unless you're building a car with a transaxle.

Right, I keep forgetting about the tranny being mated to the rear end lol But yea it's a sweet tranny! Hopefully they can make a tranny brain box like they have for the 4LXXE's.

you could swap the whole tranny and rear in.... it would be some work... but would be an awsome ride if done right.... you should go for it...lol...

lol I have a Conquest that has a independant rear suspension (RWD car if you're not familar with them) and I'd love to put it in like, a Volvo 740 Turbo or SBC.

Trust me, I thought alot about putting an older vette IRS into my 91 Firebird lol

I really want to put in the newer ride control Corvette shocks in my 93, the 3-setting adjustables.

What other cars use the 6Ls? I don't think the GTO does...

if i remember right GM has a car out or is coming out with a rear wheel drive car with the 6L.... it may just work... i will see if i can find more info on it...

Since the G8 is out, I figured I'd bump this. I believe it uses a 6LXXE (haven't googled yet to see which model exactly), and also has the tap shift ability, so it would be able to utilize that paddle shift steering wheel kit.

Anyone want to take the dive and do this?

dude having a paddle shifted 6 speed auto would be effin awesome! plus some added strength our 4l60e's dont have.

Yes, indeed it would be I think the paddle kit (which does work with 4L60Es btw) is like $600~

I don't believe the LTX, PCM is capable of controlling the 6LxxE series transmissions. I know the LT PCM will not control the 4L80E truck series transmissions. When people use the 4L80Es with their LTs, thay have to add one of the GM transmission controller modules and I think they are $3K+. Ouch!

Yea, I figured a trans computer would be needed, but I don't remember them costing $3K.
