4wd and 2wd transmission mount orientation

Recommended Posts

backstory: 2wd converted to 4wd. I left the passenger side transmission crossmember frame member intact.

I cut off the driver side bracket and welded in the bracket from a 4wd.

 

From NPORA on facebook, someone pointed out and showed me the correct orientation of the transmission mount but I for the life of me cannot get it to line up with the holes. The only way it seems to work is when I reverse the orientation.

 

Can someone with a 4wd and 2wd go under and snap some shots of the frame mounts and transmission mounts and get some quick measurements of the bolt holes on the frame mounts?

I can't help on the 2WD but I'll see if I can get a shot of mine when it's not caked in snow. You're looking at the crossmember between the transmission pan and the transfer case, right?

Here's the tranny mount itself. The two sides of it are shaped differently. The one with an edge facing the ground is on the trans side, and the one with a 90° bend facing the crossmember is on the transfer case side.

Here's the driver's side where the crossmember meets the frame, looking forwards (frame rail on the left, exhaust pipe on the right). I'm noticing the frame mount has extra holes in it--possibly for mounting a different crossmember? Or mounting the same one shifted back a bit for some reason? I don't know if it's even possible to bolt to those holes, but if it is, and you did, that could be why your trans mount isn't lining up.

And the passenger's side, also with an extra hole showing just behind the crossmember.

(The lot of these are at https://www.flickr.com/photos/158412646@N06/with/39419842172/ if they're not showing or you want higher res or something.)

I took a rough measurement bolt center to bolt center (eyeballing center) and got around 3.58 cm (probably more like 3.6cm, looking at how centered that left jaw isn't). This measurement appears the same on driver's and passenger's sides.

 

Let me know if any of this is what you're after, or if you need more/better measurements.

Thanks for the photo confirmation. So how I have the mount orientated is the correct way now. I guess it's just a matter of me pulling the right bank of the engine and transmission rearward so the right side of the transmission bracket will line up.

Yours looks a little different underneath than mine! Good luck getting the bugger lined up.

I got the bugger to finally line up. It was a damn balancing act for sure. The bottle jack on the jack did the trick. I just need to refab the RR engine bracket to fit my bent frame. 30d33317ac1c87c24a4f1f0efaf6f7fd.jpg8726d2eba2fecd052be9f1f8107b3ed5.jpg
