Thanks, but is that for the nut goung through the crossmember or the mount to trans? I need all the specs including crossmember please.

it is 18 for the mount to the tranny. i am not sure about the ones from the mount to the cross member or the ones from the crossmember to the frame.

I saw the 18 for the mount to the trans. The nut on the bottom (mount to crossmember) and the crossmember (to frame) are not listed. They are for the t56 in the link you provided.

I see that they are only giving the spec's for the cross member and the mount nut for the t56. However the mounts and the cross members are basically the same and I think that you will be just fine using those spec's. I will have to look at the service manual when I get to the shop today and verify this for you. Vince

Thank you!! I was going to use those as well because I figured the same as you...it can't be much different.

if you tighten the bolt past 18 ft/lb torque will that cause a lot of vibration from that area since there is more pressure? when mine was put on it was just tightened really well. we didn't go by torque specs.
