1990 and I-6 should be an AOD.

Cooling, cooling, cooling. If you don't already have one, get a tranny cooler (don't rely on the one that just goes through the radiator). You might also consider a secondary filter; there's a picture of mine in my signature link on the Bronco.

if you have the pushbutton OD on the dash then you have the E4OD. cooling is the best thing and anual service as well. B&M makes a nice cooler that mounts in front of your radiator.

Hayden Rapid Cool ....

If your Bronco doesn't have one get the Rapid Cool from Hayden it's been top rated in almost every performance test.

Get the 10,000 lbs one. It's fairly easy to install.

I also use Mobil One synthetic ATF.




If you get so motivated you can install a higher capacity deep tranny pan with magnetic drainplug too. I use this one from PML.

Then to monitor the tranny temperature I installed a Cobalt tranny temp gauge from Autometer.



These guys had the best price, other than Ebay.

I think that's about all you can do for it. It's a big pain in the butt to replace a Bronco tranny, so good routine maintenance is very important to the life expectancy. Good luck.
