wish this guy would at least come back on here so i could get his name so the drive shaft company can look up his data for future cust. that want to do this swap also.

Looks like I'm going to do this swap too. I was just about to do a 6L90 out of a 2500HD truck but the tail shaft output is way off. The length and mounting points are much longer and farther back. I don't want to risk it being hard or imposable to make those mounting points work. Would be cheaper if it worked, but I'm not going to risk it.

I'm really questioning if you actually have to reflash the TCM at the dealer. Both transmissions seem to function the same, so the operating system and firmware should be the same. It may take some different settings and adjustments in the tuning. But that's something any tuner should be able to do. Even if you just copy and paste the stock ZL1 values, that should work the same as a ZL1. Tampa Tuning, what do you think about that?

there has been many changes to the valvebody / tcm over the years ( remember the tcm is built inside the trans along with the valve body), the correct o/s file must be flashed to the tcm, if you order the zl1 6l90e then you need to flash it with a zl1 file to start with , then read it out and modify it for your vehicle

flashing it with the wrong file will brick your valve body/tcm

Really sorry I have been on in a while guys, been a busy summer Kart racing and fishing . Trans is working good so far, customer is happy with it. Do not have any track times yet to see if there was any improvment but at least its holding up on the street.

i dont know why you guys are wasting your time with this swap..

Z1500

More clutches per pack seems like a good reason. Why are you saying it's a waste of time?

The Baron

I had one of the first 6l80 corvettes in the country in the tens, I own a ctsv coupe that runs 11s and is a daily. The amount of time I have WASTED with these six speeds is large. You have great company s like RPM doing nice reliable 4l60 swaps that will support 650-750 hp all day, even in heavy cars like the fifth gen for what I can't see being any more money money than this 6 sneed swap you guys r doing.

Z1500

You are certainly not the first person I have heard this from. My hopes and dreams are that newer techniques by the aftermarket are maybe greater now than anything you had tried? Maybe starting with a factory better trans that has 150hp greater power capacity than the 6L80 to begin with. I know a couple guys making 900+whp through built 6L80's in Camaros, but it has only been a couple months. It seems like it can be done, but may require expensive rebuilds at a much shorter interval. Maybe a rebuild every other year. I could live with that.

not an expert but i play one on tv... anyone that is spending money on a 6-4spd swap and doesn't go to a 4l80e is wasting their time. a stock 6l80 is equivalent to a th400 in terms of max torque. My friend's 950whp pro charged camaro still has the stock 6l80 in it and it shifts fine. car is on 20" camaro wheels (Nitto DR's).

If you're really hard on the car, like non stop beating the **** out of it then i could see the 90 swap, but it's still not as strong as a 4l80e. the 4l60-65-70 is a joke compared to the 80. for almost the same cash, i would go 4l80..Turbo LS3 Impala at my friend's shop obliterated a built 65. Car makes 750rwtq. That trans was top of the line. He's now going to do the 80 (which he was advised to do in the first place by the builder). Maybe one of the trans builders can come on in and straighten some of this out.

The Baron

The 80 has its place. But being a much heavier trans and the fact it requires a lot more hp to run it ( loss through the trans) and the fact rpm has 4l60s GOING IN THE 8s in fifth gens really the 80 is most likely overkill..

I have a customer wanting to do this swap on a 2010 Camaro.. For reasons of keeping a 6spd, cruise control, paddle shift, etc he has adamantly stated that he would NOT go with a 4spd automatic.

Anyway, would the stock ZL1 driveshaft work? Is there a difference in the rear end, or in overall length (aside from the transmission) that would affect the driveshaft?

This is very interesting

Fire67, I wondered that also but never had a ZL1 to take measurements off of. And even being a GM employee my cost was like $750 if I remember correctly for a stock ZL1 shaft. This is why I didn't waste the time ordering one and take a chance of paying the re-stocking fee if it didn't work.

No Hope

any updates on this?

The 6L90 has been in the car since spring or summer of 2012, still running good and is now more of a daily driver. Guy that I did the swap for actually sold the car to my neighbor (his wife drove it every day this summer). Seems to be holding up good, runs a low 12 at full weight when it makes it to the track. I think there could be some fine tuning make to the trans tune but very happy with what Phil at Tampa Tuning was able to due from the other side of the country in a short amount of time. Bringing this thread up makes me want to get in touch with him and see what he could do now that the A6 has been out a while now.

DirtyBird- do you have any info from when you called DSS for that driveshaft?? any account reference? save me a trip of having to drive there just for measurements.

nightmare2012

Thinking about doing this swap as well I wonder if the 6l90 off a truck (2500hd) will work the same.

Did anyone ever figure this out?
