Something you guys with 700r4/4l60e and custom exhaust might want to look at
 

So I won an auction with Hawks 3rd gen (camarohawk) for a used crossmember for a 4l60e , but instead this is what showed up ...

So naturally I thought maybe the picture doesn't meet the description ...

The ONLY thing I have to do to make this cross member work is weld a plate on to capture the bolt on the mount .. its already sitting on the member I just can't do it up proper because the bolt is just shy by about 1 inch..

This is awesome because I was just going to modify the 4l60e cross member anyways .. This is going to work soooo much better ..

I dont understand? that cross member is made for the 4L60e tranny. Mine just bolted right in. Not sure why yours didnt??

He has a 700R4 according to his signature, but he modified a 4l60e crossmember to work with the 700R4.....or atleast that's what I get from it.

Yes Exactly.

Looks nice

I would have chopped the extra material off the rear of the crossmember before sticking it back in there

bringing this back....how is this working out? I am looking to install one and was thinking of doing the same for a 700R4. However, I was just going to drill holes through the mounting sides to get access. Anyone done this?

The frame rails arent parallel so drilling holes to shift it forward wont work. The simplest solution is to weld an extension like he posted. I prefer to build trans crossmembers from scratch because they never fit out of the box regardless of brand/chassis

... and building the crossmember around the exhaust is easier than the other way around.

Can you try something like this instead?

To build my own is there special materials I need or just go to HD or Lowes and get some angle iron.

Re: Something you guys with 700r4/4l60e and custom exhaust might want to look at
 

Angle iron and commonly available plate is typically made from A36 steel (36ksi yield strength), which is less of a concern in your application than the material thickness, the geometric configuration of your design and the quality of your welds.

Two 4' sticks of 2"x1/4" mild steel from lowes/HD is more than enough. Will have left overs for future projects and frame tabs. Weld sections together to make angle instead of sourcing it

So when you did this, did you have to slot the new trans mount hole? I am doing the same, but when I did the test fit, the transmission was not in line with the hole in the crossmember.

I can't shift the transmission over, because it is already in contact with the new crossmember (I have already cut that portion off so it won't contact now.) Here's what mine looked like before I added the extra metal.

Yeah , I had to drill a new hole and cut the excess from between the new and old holes.
I wish I could show you a picture, but I already got rid of this setup for a T56.

Did you also have contact between the fuel/brake lines and the crossmember? That's the only other thing that I have to modify for this to work; and that's not to bad, IMO, considering this wasn't built for a 700r4.
