Check the electrical connection on the O/D button, does the light on the dash stay on?

big jim

The light comes on when I push the button then goes off when I push it again

Hey Jim, is the engine getting up to operating temp? I know with my 2nd gen it does not go into O/D until then.

The ATF has to reach about 170 degrees Fahrenheit before O/D kicks in. This is also true for the converter lockup. ( At least, that's the way it works on my 92 model 3.0 )

Check the plug on the tranny????

There's a bundle of connectors on the passenger's side, near the alternator which comes from the harness and goes to the various solenoids, sensors and switches on the transmission. This is a problem area for some vehicles of this age. Check them out, make sure there isn't any corrosion or disconnects, etc. Also, might want to check the ECT box under the console in front of the shifters, make sure it's plugged in securely and that there aren't any corrosion/dirt problems with it's connector as well. I'm not sure if the light will come on or not if that box is unplugged.

I'll check the temp thing it doesn't have a thermastat as the guy that had the truck that I got the engine from said he could not keep it from overheating with one

Thans guys. it was the temp. I got it good and warm and it shifted into o/d I am going to put a thermastat in it. and it should be good to go. what temp thermastat should I get?

If your cooling system is in proper working order,, go with the 180. You'll appreciate the fuel mileage improvement.
