brox Posted February 8, 2012 Share Posted February 8, 2012 I've got an '87 GL wagon with an AT and I'm planning on swapping in a d/r MT from an '85 wagon. The MT is shorter. I've got the longer drive shaft and all of the otehr transmission related bits. My problem is the transmission crossmembers are completely different. And the mounting points on the car for the AT are further back. I plan to keep the MT crossmember on the MT and the AT crossmember on the car frame, then fab something that connects the two crossmembers. I assume I'm not the first to do this swap. Can anyone tell/show me what they have done in this case? Much appreciated. Link to comment Share on other sites More sharing options...
Gloyale Posted February 8, 2012 Share Posted February 8, 2012 The MT crossmember bolts into the chassis at the rear/ inner bolt for the radius rod plate. Ditch the AT crossmember. FWIW, there are some rubber washers with a spacer that are supposed to go with the crossmember.....they may or may not be in the MT crossmember ends. Big washers will work, but the vibration will be more. Link to comment Share on other sites More sharing options...
brox Posted February 9, 2012 Author Share Posted February 9, 2012 Wow. Good thing I asked. That's a lot easier. One side of the MT crossmember has it's washer. Might have to hit the junk yard. Also, one of the rubber dampener things that connects the MT to the crossmember has separated. Is there any way to re-adhere the rubber to the metal that it has separated from? Thanks.

Put all the pieces together in the proper sequence Set them on top of the cross member where the bolt hole is Insert the bolt and tighten That's all! The pressure will hold it together Link to comment Share on other sites More sharing options...
man on the moon Posted February 11, 2012 Share Posted February 11, 2012 And welcome to USMB. And don't be afraid of that search tab up at the top/right-of-center, a lot of information is already here and will save you waiting for a response if you use it.

The pressure will hold it together Uhhh....... I don't think you get it. He's talking about the trans mount....not the rubber washers for the crossmember. Once the trans mounts rip, get new ones. they don't get held toghether by the mounting bolts. You can use ones from any EA82 4wd 5spd, Single or Dual range.

MilesFox Posted February 11, 2012 Share Posted February 11, 2012 THe MT crossmember has longer bolts then the AT crossmember. This is probably what he means. The at crossmember bolts in with the radius rod plates, but the at mounts to the tunnel further back. So to use the MT crossmember, you need the longer bolts and the rubber washers to replace the shorter bolts as the mt crossmember bolts where the radius rod mounts bolt to.

I was not talking about that. I think in this statement : "Also, one of the rubber dampener things that connects the MT to the crossmember has separated. Is there any way to re-adhere the rubber to the metal that it has separated from?" He's talking about the trans mount itself. And if it's torn, he needs a new one. Simply bolting all toghether won't hold the trans down. The trans will sit fine under acceleration, but the tail will lift in reverse, or under decelleration/engine braking.

Idasho Posted February 11, 2012 Share Posted February 11, 2012 yeah, he is talking about trans mounts. Still available from Rockauto BTW Link to comment Share on other sites More sharing options...

You are right--I apologise! Thank you for correcting that. Link to comment Share on other sites More sharing options...
brox Posted February 12, 2012 Author Share Posted February 12, 2012 I should have checked back sooner. I could have saved a little confusion... but you got it. I was talking about the mounts that connect the MT to the crossmember. I'll need a new one. After putting everything together, I noticed that I'll need longer bolts to mount the crossmember to the chassis. (As well as a rubber washer/vibration dampener since one is missing.) Thanks for all of the help. I'll make more use of the search function. Now let's see if I can get it the engine all hooked up... Link to comment Share on other sites More sharing options...
