WTB three speed cross member - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Don Brace** · 07-08-2009, 09:40 AM

Looking for a three speed cross member. Is this the same as the auto cross member? Would like to see a picture of the three speed cross member so I know what I am looking for.
Thanks

Don,

From what I know the Auto trans is the only trans that needs a cross member. The Manual trans dosent. I may be wrong.

Hope that helps.

Brian.

Don,
The picture in Prathbun's post is a good representation of what you are looking for..
The manual trans mount is technically a crossmember that is riveted to the frame.
One thing you need to look out for is Chevrolet used two different versions, (not sure about GMC's) a 6 cylinder one and a V8 one,, they look almost identical unless side by side.. the V8 one sits farther forward than the 6 cylinder one..
Sorry I can not help with any pics..

Thanks for the information. I am going to the IOLA Wi swap meet today and will look for one. Looks like the one in Prathbun's photo mounts under the bell housing. Is there one that goes under the trans mission?
Thanks

I have two here camne get a pic later, but $10 plus shipping for eithr one, I am not sure if they are 6 or 8 as stated above. I do know they are for a standard tranny. SHipping would be 20 or less I would guess...Randy

Randy
Are the two you have the same or are they different from one another?
I am off to IOLA WI car swap meet and will get back to you on Saturday. My guess is the only difference between the six and eight cross member is the mounting holes which is no big deal. I looked under my truck and there are two sets of holes to mount the cross member.
Thanks
Don

No, not with standard transmissions. Automatics only.

Yep I am purty sure not under the tranny, just the bell housing

**Don Brace** · 07-08-2009, 12:31 PM

Currently I have an automatic crosss member under my 3 speed overdrive and none under the bell housing. I have lots of clutch chatter and think that not having the member under the bell housing maybe part of the problem.
Thanks for the replies.

Don..
from the factory all the trucks used one under the belhousing..
GM cars used one under the trans, if you have the surface on the tailshaft of your trans for a mount you can use the stock truck automatic crossmember.

oops, replied to your original post before I saw this one..
If you have alot of clutch chatter it is more than likely for some other reason than the rear mounted crossmember... probably either a warped flywheel, bad clutch disc.. pilot bearing worn out.. bad input bearing in the trans etc..

I'll check on the clutch and the pilot bearing and let you know.
Thanks

Don, did you find your parts at iola? If not, i will see if i have something here on a parts truck if you still need it. Eric

Eric
I am still looking for the three speed cross member and the inner passenger side rear bumper bracket. Also trying to figure out why my power steering pump is so close to the alternator bracket that I cannot get the P/S cap off.
