Camaro 6L80 switch to a slip yoke
Anyone know the part numbers required to switch the Camaro version of the 6L80 over to a slip yoke. Or know of anyone that is doing that?
Thanks!
Cheers,
Jay

The 6L80 has the same 32 spline pattern as any turbo400 or 4L80. So almost any 3/4 ton or bigger GM truck should have the slip yoke that you need. As long as the Ujoints are the same size. But make sure you don't get one from a truck with the 6L90. That's a 34 spline. I don't know if you do your own work or buy used parts, but this would most likely be the best way to go. Hope it helps.

I'm interested in the part numbers if anyone has them. Even an exploded view of one of these transmissions would be helpful. And yes I would probably do this project myself if I could get the right information. But at this point, I’d be happy to send it somewhere to have it done too.
I've tried the dealership, they are clueless. I've tried about ever transmission place in Denver. Driveshaft places here don't seem to know either. I ended up buying the driveshaft for the 2010 Camaro that bolts to it. But I’m not a big fan of how it’s going to mount and the driveshaft place here said they would have to send it to California to have it altered for length since it spin welded. I’m willing to eat that purchase if I can get this transmission switched over so that I can use a standard driveshaft.
I’ve seen pictures in the Conversions and Hybrids section here at LS1 Tech before of someone’s swap that they had changed out the tailshaft with this bolted connect to a slip yoke. But I can’t remember who it was or even what car it was.
Unfortunately my whole project seems to be at a stand still till I get this figured out.

I was doing some looking and this thread has pictures of all the transmission in a new Camaro: http://www.camaro5.com/forums/showthread.php?t=20654
Since the 6L80 is used in trucks and cars, they won't change it specifically for the Camaro. The trucks have a slip yoke, so theoretically you should be able to unbolt the flange on your output and just use a slip yoke in its place. Here is a part number that "should" work for you. 699-7685
If anyone can confirm what I'm saying, I know you would feel more comfortable about it.

Exactly my point! I was pretty disappointed with the dealer, but unfortunately those guys just aren't car guys. Since I couldn't tell them a part number or a year or model of truck to get the parts from, they couldn't come up with it on their own.
So hopefully if I keep this thread alive someone who has done this will see it.
Thanks guys!

It's not that they are not car guys, it's the system they have to use, number of models they have to deal with and the way they normally look up parts for shop.
They need to know year and model of vehicle, and if transmission or engine, the code LETTERS for them as model may have more than one engine or transmission used for that year.
Before I walk into parts dept, (I don't call them) I know that information. If I can get a Caddy dealership parts man to look up 6L80E and 6l90E parts numbers for me, you should have no problem with a Chevy dealer, I don't and Caddy parts man just took a little more looking pitiful and telling him I was working on swapping trans into and older car...
You can find the information for 2010/2011 make and models on GM power train website. Most of the times that info is same for prior year models too, are close enough for them to find the part.
Another interesting fact is 6L80E gear ratios for trucks are slightly different from what the Corvette uses an if you think about it, it's easy to understand why.
Now when it comes to yokes for my A6 6L80E and my A6 based 4L80E, they are not alike. MY 6L80E one is huge compared to the 4L80E yoke....LOL

Try PM'ing member here by the name of John McGraw. He did a G8 A6 conversion into a Chevelle wagon and had to convert it to slip yoke. It's not a simple cheap change either, if I remember correctly. Best to go with truck 6L80E instead.
Also read through RSZ228's thread and write down part numbers that might be of help to you later on.
Street and Performance (Hot Rod Lane) has a couple of 6L80E conversion parts that might be helpful also.

Digging around for close to 10 plus hours on the internet I came across a couple of part numbers and diagrams. One is for the Camaro’s version of the 6L80 and the other is for the Escalade version.
Makes it look simple, but it doesn’t show the output shafts. That’s where it could get a wee bit technical and a whole lot more expensive. I’ll keep you posted.
Thanks guys, today is a good day. Haven’t had one of those in a while.
Cheers,
Jay

I was trying to source this 2 years ago and there were no people that could help me then. Now through my own research I figured that you would need to change the output shaft/drum Assy, the tail housing and bushing and seals, and the yoke. From memory these parts were around the $900 to $1000usd mark
So if you can source a truck trans and sell you're existing you would probably be in front. Otherwise do as I did and attach a machined down t400 truck yoke and fit a slip joint in the tai shaft. If you can find the parts to do this let me know as I still want to convert mine to a slip yoke like the truck trans.
Tomorrow I will dig up the part no.s that I collected and post them

I agree with 68sstt. I wouldn't screw around trying to convert the transmission, I would just sell the current one you have and buy one for a truck with 2wd. I was in the same boat over a 1 1/2 ago only finding 4wd versions of the 6l90e. I looked around and found a 2wd version for $800 and used it.

then i had to machine the yoke to replicate the 3 bolt yoke, it required some length machined off and a step machined from the inside at the trans end.
Then i got a slip joint installed in a tailshaft that i had made a per these 4x4 shafts.
http://www.dennysdriveshaft.com/c4_4x4_driveshafts.html
The only thing that has to be done is the alignment spigot on the end of the output shaft on the trans needs to be machined back to allow the u joint to fit. I'll try take some photos of my shaft and post.

Thanks 68sstt, I would be VERY interested in seeing some pictures.
My biggest dislike with the Camaro driveshaft is the center bearing. What I don't like about it is, that the bearing is fixed to the slip joint side and not the fixed side. It just doesn't make any sense to me and kind of the major reason I'd like to go a different direction now even after buying it. So putting a u-joint at the bolted trans connection and using one of their shafts, that don't require a center bearing, seems like a MUCH better idea.
The local driveshaft place jokingly said not to worry that we'd get it right the second time. I know he said it jokingly, but those words are haunting me right now.
Thanks,
Jay
