Crossmember is $116.18 (INCLUDING SHIPPING) from GMPartsDirect.com

 

What does this crossmember look like? Does it have 4 mounting holes?

 

I couldn't find a pic of the crossmember, but my parts guy said that it was definitely for a 1500-series truck.

I would think/hope/pray that it will bolt up to any 1500-series frame. Anyone have or know someone who has a 1500HD to check?

 

well, if it's FOR THE 4L80E, then i would assume it would have the proper mounting holes for that particular transmission.

 

I'm not worried about the mounting holes for the tranny...I'm worried about where it MOUNTS TO THE FRAME.

 

will it bolt to the truck is the question, i would have to see it to believe it.

i know my ecsb had a diferent cross memeber than the rcsb i have now, completely diferent.

 

i'll call a dealership over here tomorrow and see if they have one in stock....maybe they'll know if it will work on a RCSB halfton...

 

Check out this thread for some pics of 4L80E 2500 and 1500HD(same thing ) crossmembers.

ok here are some pics of mine. had to cut the hump out of it for pan claearance and when i boxed it back i angled the new metal downward and towards the front so the 4l80 pan can come off without removing the crossmember.
