auto trans crossmember same as a 4 speed crossmember?

[mopar4don]

Is the auto transmission crossmember the same as a 4-speed crossmember in a 69 Charger?
I can't find it in the parts manual.
And this is all I could find in the service manual

no, i did not know this ether until i i had them both out. the mount actually sits out board of the cross member an the auto were as the mount sits in the center of the cross member.

When I swapped a 4-speed into my auto 1970 road runner, I used the same crossmember but turned it around backwards and it worked fine.

It is the same cross member, but the auto has this extra bracket on the side to drop the mount in.

Turning around is a good idea!

You can modify the auto crossmember to work...done it!

The trans crossmember on a 69 is different from a 4-speed to an automatic but as mentioned can be adapted by cutting out the center to let the mount go down in there. In 70 4-speed or automatic are the same crossmember that is providing you are using a 70 4-speed trans if you are using a 69 or earlier 4-speed trans it would be a different one for automatic or 4-speed. There are also differences in the bolt hole size in 70 crossmembers on the body and trans.

Yep did the same here.

HI Moparparts- i just started a thread a few days ago on my auto to 4 speed conversion in my 70 RR. I have a 69 trans. From your post it sounds like my 70 auto trans crossmember won't work on my 69 4 speed. Can I just reverse it like it was mentioned in this thread or do I have to get a 69 crossmember? Thanks.
