Default My BMR 4L80e crossmember doesn't fit right

Kinda miffed about this, because I found two other threads about this exact issue from a few years ago, and apparently it's still a problem.

I have a 1993 4L80e that I am swapping into my 2002 Camaro. I bought the BMR 4L80e crossmember/tq arm relocation setup and can't install it because the cross member rubs on the rear passenger corner of the transmission case/pan area.

Here is another thread on it:

https://ls1tech.com/forums/automatic...ossmember.html

Here is the part that rubs:



In the thread linked above, someone talks about notching theirs with a cutting wheel then re-welding the hole which I don't want to have to do considering it was a $250 piece of hardware. I guess I don't really know what else to do except contact BMR on Monday for advice, but thought I'd see if anyone else ran into this problem because I know a lot of you have swapped 4L80e's into your F-body's.

Bummer. I had to cut, reposition, and reweld the torque arm mount on my 4l80 cross member. (I can't recall for sure who made mine, but I know it wasn't the one shown in your pic.) Any chance it would clear if you could heat it and put a good dent in it there?

It sucks but that's the way it goes with many after market parts...

I dunno, it feels like it's pretty thick metal.

What other options are there? Not that it'll help me at this point, but maybe someone else can avoid this part if it's defective, which it seems to be.

I have a moroso deep pan that it wasn't clearing at the lip. Looks like about the same problem here.

Mine is just the "regular" factory pan. What did you end up doing to get it working?

Can you put a small spacer between the trans mount and cross member? Just be sure to check the angle at the back of the trans.

I dont know that a small spacer would give enough clearance, unfortunately.

I didn't want to jerry rig it so had a chassis shop make another one like I should have done to begin with.

Yeah, I got right through when I called and spoke with someone very friendly and helpful. Guess I should have done that to begin with.

From what I gathered, they are aware that some out of spec ones made it out to the market and are offering replacements to anyone that got one. I don't imagine it was intentional, but hopefully I get my replacement soon because I can't really make further progress on my build until the transmission is secured in place.

Would there be a problem if I made the slots bigger on cross member to where it would slide back far enough from trans, I didn't think of any. Just wonder if anyone would know.

Thanks justin

I must got a older one then, bought it as a whole setup from a buddy, was going to cut slots in the way I need the cross member to slide on a mill. I will have pics to up date on how it works out, be Mon before I get a chance to do it.

Sorry to bump an old thread but I am also have the exact same problem. My transmission pan is rubbing on the crossmember and the trans mount does not line up. It's about a half an inch away. BMR TC0021. Going to call BMR tomorrow, supposed to be on the dyno Saturday ughhhh
