Transmission mount help

[JerryL27]

I'm putting a 700r4 transmission in my 1983 cutlass. I have a G force crossmember to fit it as well. Is it a certain transmission mount I need because I'm having trouble getting the transmission to line up with the crossmember so I can bolt it down

I used the stock mount for the 700 and modified the mounting tab on the crossmember for my El Camino.

Ok my transmission isn't lining up with hole in the crossmember. It's off line

That's because the strock A/G bodies used a crappy offset transmission mount. Trying to use the standard mount doesn't line up. What I did was cut off and relocate the tab on the stock cross member and then a poly mount fit. I would have thought the G-Force would use the better mount location. Maybe try both types and see?

Ok I will try to modify it. It would seem that the g force would go in with no problem but it want. Thanks for the info.

Here's a pic of my adapted poly mount, and the stock crummy one. The tab was moved about 3 inches to starboard.

I have a 700r-4 in my 84 cutlass with gforce crossmember and used a stock 700 mount from camaro and had no problems. There might be another issue there.

Do u remember the part number for the mount you used

 

[Bonnewagon]

What kind of misalignment are we talking here? Left/right or fore/aft? If left/right then what I said applies, but fore/aft could be the cross member attachments at the frame rails.

The transmission mount bolt is sitting to the driver side of the crossmember hole. I'm not sure if I need a different mount or what. Looks like the motor is sitting in like it suppose to
