AT crossmember correct? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

ccautoupholstery · 11-15-2015, 03:48 PM

I can't tell if I have the crossmember in the correct location or if it's upside down. I still need to swap the new mount with the rubber on the trans itself

It appears to be upside down to me, seems it would fit better the other way, try it...

I think it's upside down too. I just installed a tubular one yesterday. Never saw one like yours. The tubular one I have is nice because it's got better clearance for exhaust pipes. It was $72 to the door on evilBay.

I was thinking it was upside down too...can you post a pic of your tubular frame? I got mine as a complete kit, tubular motor mounts and the crossmember you see in the pics

EARNHARDT#3 · 11-15-2015, 06:29 PM

This is the one I have.

ccautoupholstery · 11-15-2015, 07:11 PM

Any chance you have one of it mounted?

No but the next time I'm under there I can take a picture.

Your transmission crossmember is correct. I believe that's a gmc Paul crossmember. The ends that mate to the frame are a C channel right? If you flipped it over the trains would be above the top of the frame. Your pictures ( or truck) however, are upside down.

ccautoupholstery · 11-16-2015, 01:37 AM

Not sure if the gmc Paul but yes on the c channel. I put a pic of the kit I bought. It fits great but came with zero info and I don't wanna have to pull it all apart bc it's upside down :/

put mine in yesterday. and the flat side on the trans mount is level with the upper frame rail. I hope that is correct. My frame is completely bare, I have nothing to go my except memory

Now that I see a good picture of the mount you and the OP have I believe his is mounted correctly and that yours is mounted incorrectly.

ccautoupholstery · 11-16-2015, 11:10 AM

So I've seen both answers, should the flat side be sitting flush with the top rail or drop down?

It definitely can't sit flush with the top rail. Your transmission tail housing would be pointing WAY high.

How's that ol' saying go? A picture is worth a 1,000 words. Here's my truck.

**tjc** · 11-16-2015, 02:16 PM

I guess I better change mine today, before I go any further. Thanks for the pictures.

EARNHARDT#3 · 11-16-2015, 08:02 PM

Here's a picture of mine as requested.
