For three years of messing with this car I've changed out the transmission fluid twice. In the fall I cleaned the bottom elongated screen and one tubular screen. Never helped. Getting on the interstate today on a unusual warm and sunny winter day. The thought came to me to try and use the overdrive. I felt some hope that it might work for some reason.

Attempted it and the overdrive kicked in. Cruised over 70 somewhere around or below 2500 rpm. Over 75 was still quietly under the 2900 rpm mark. Quiet motor and the feeling of wanting to go faster. Never felt that yet in this car. It handled pretty well other than the front suspension needs replacing and the pan hard bushings are shot. Not sure how the IPD Cam gear is adjusted but it kind of feels like its got a little less torque than my 86 but with the rpm's staying lower too. Maybe I'm imagining things.

On the way home the OD slipped out of gear when I hit the brakes dropping my speed from 70 to 60. It seemed like the transmission was in neutral with my rpms having no or little effect on the driveshaft. I shifted out of gear and then back into 4th at 55 mph. After the construction zone I got back into OD and it ran fine. 2200-2400 rpm at 70 (might be more since speedometer is under by 3 or 4. My guess is that its still in need of servicing or possibly it needs more fluid. Drips a slight bit. But I've now got overdrive.
