In my post, he recommended '89 and newer which offers most of the upgrades and redesigned oiling system.
I'm not aware of any particular problems with the '87 model year. You will probably have it rebuilt when you have the output shaft installed. Any reputable trans shop will put them together with the most recent updates.

I haven't had much experience with overdrive autos. I've always taken my stuff into the local trans shop to be built. A guy that I worked for had an AOD in his Bronco. With 4.10's and 33's, it was geared just about right. Much higher gearing than that or taller tires and you will rarely get into overdrive. The AOD has a really high OD (around .67, I believe).

After you get it installed, take it to a transmission shop to have the throttle valve cable adjusted. This adjustment, which controls shift points and feel, is critical for long transmission life according to my rebuilder.


HTH,
