It will work. The factory LS1 cars have a longer yoke than the 700R4, don't know why. Otherwise it's the same and will work.

Cool. I had a 700R4 behind a 350. Maybe I won't need to modify my driveshaft at all. I've been told that the length is the same too. Hope that's accurate.

Well. It turns out that it does NOT work. Here is a picture of the yoke to my 700R4:

Here is picture of the 4L60e splined shaft:



(Ignore the dirt and crap...I will be cleaning it up )

Notice that on the 700R4, at the bottom of the pic inside the yoke, that there is one wide slot. On the 4L60e, the splines are all small, no wide slot.

Now the drage is, that if I have to get one for a 4L60e, and it is longer, then I'll have to have my driveshaft shortented.

Bummer.

The 4L60e yoke has the same wide slot. I'm running a 4L60e yoke in my 700r4. If I remember right the 60e yoke is only like 1/8" longer, so it shouldn't make any difference.

If you look at the picture of the 4L60e above, there is not matching wide slot, just all small splines.

Are you saying then that 2 of those splines fit in the wide slot?

I had thought maybe that was the case, but I'm having difficulty putting the shaft in. But maybe I'm just not getting it aligned up good. (I'm fighting an X Member in the convertible).

If that's the case, I'll proceed, but I want to be sure as I don't want to mess up the splines trying to get the wrong yoke on.

LT-x7

That's it, I have no idea why so don't ask.
But it WILL work.
Good luck.

It's more like a missing spline, it will go on there.

If you don't like the way it looks, go buy a new one.

I could care less how it looks. I just don't want to be forcing it on if it isn't supposed to go there. Thanks for nothing.

LT-x7 and 8a8mfh: thanks for yoru useful replies. I'll get get it put on.

Ok. Once I knew that it in fact should work, I got it in. I had to jack the tranny up a little, as I found it was just too tight in the crossmember.

Now, I have a new question. Apparently the mounting of the LS1 is somewhat forward as it realates to the transmission, and the yoke does not go as far into the transmission as it did when I had the 350 and 700R4. This based on teh length of the drive shaft, and once I mount it up to the yoke on the rear end.

Check out the pic to see how much of the yoke is outside of the tranny. I'd say I have about half, or maybe a little more, of what could go into the tranny. Anyone think that's a problem?

Based on the rust line, you can tell how much less is going in than did on the 700R4.

Thats not enough. What are you working on there and what are you doing to it. I ask because it doesn't sound or look like a basic trans swap.

Don't blame me for you being an idiot, blame your parents.

ewingr

I was afraid of that.

You're right, it's not a basic trans swap. I'm putting a 2004 Corvette LS1 and a 4L60e into a 1956 Chevrolet convertible. The tranny is the same lenght, etc, as the 700R4, but the engine being different from teh 350, has to sit forward more, which brings the transmission forward.

Sigh...this has been an expensive project. Fun. But expensive.
