Question for tranny swap.

[MazaM]

Hi to everyone. I'm turning to the board for some needed advice. I currently have a '80 2WD with a 305/350 tranny with the reverse starting to go out. I've been keeping a eye in the local classifieds for a used 350 trans to swap out. I may have located a 350/700 setup out of an 85 for a good price but not sure if it would be a direct swap. If possible, I would like to use the old 350 engine as a core for a reman, then bolt the the 700 back onto it and place it into the '80. Would that be a relatively easy exchange or would some modifications be involved? If not, what trans should I be looking for?
Thanks in advance.

You would have to shorten your driveshaft and most likely move your tranny cross-member back. Other than that it is pretty painless. Make sure the 700 is in good shape. Stock one tend to go at 145,000 miles.

it is an easy swap but the driveshaft and crossmember do have to be adjusted the only thing that i can remimber.

The only other things I can think of are to make sure the TV cable is hooked up and adjusted correctly, and you will want to make the lockup work as well. I used the painless wiring kit in my Blazer, but there are instructions on www.73-87.com as well, I believe.

You might want to have a transmission shop go through the 700 and make sure everything is in good working order. I know you dont want to put it in, and then have to take it back out to have it rebuilt. I know that my 700 went out at about 170,000 on the dot.
