Converter & Track Results

The car is back on the road as of tonight. With the help of my brother, I was able to get the transmission back in place and get everything else bolted in. Everything went pretty smooth, except for trying to get the converter to seat in the transmission. I had been running a Lentech hardened input shaft and for what ever reason, the new converter would not seat with it. After 3 hours, yes, 3 hours, I finally yanked it out and stuck the stock one in there.  The converter slid right into place.

The car now has a Lentech valve body and re-worked Art Carr converter. The valve body not only firms shifts, but adds an electrical OD shut off solenoid and changes the shift pattern from 1 D OD to 1 2 3/4 so you can hold gears for as long as you would like when shifted manually. No need to do the AOD shuffle. The converter is a 9.5" 3000 stall with a stator upgrade and direct drive eliminated. It actually started life as a 4R70W converter and was changed over to an AOD application.

I'm a little uncertain as to how I like the converter. The stall seems pretty high for this car, as it is hard to do much driving without the rpm's being around 3000rpm under any sort of load in all gears. I'm sure the smaller diameter affects the feel of it as well. I guess it will take some getting used to. It certainly likes to smoke the tires more than it did before.

I do not have too many pictures, as there wasn't anything too exciting going on. I did do some work on the center console for the OD lock out switch that turned out pretty well. My Cougar did not come with factory fog lights, where as most (all?) of the Thunderbird SC's did. So I took a console top from an SC and used the fog light switch for my OD switch. Ford was nice enough to run the wiring harness for it so all I had to do was splice in the 1 wire from the transmission and plug it in. Now I have a nice lighted factory switch that pretty much no one but myself will know it shouldn't be there. While I had the console top out, I took the time to sand it down and repaint it. It turned out really well, except I should of masked off the rubber shifter surround, as the paint does not seem to be getting along with it. It's still a bit sticky

After getting the transmission installed on Tuesday, I thought it would be a good idea to take the car on 730 mile trip this weekend and make 6 passes down a track before heading home.

Other than a small vibration at 70mph, the car ran and drove very well for the entire trip. Even with the new gears and converter, I averaged 22.4 mpg on the drive home. I am extremely pleased with how the car ran at the track. The new setup really gets it out of the hole in a hurry and it ran cleanly all the way down. My best run of the day was a 13.57 @ 98.72. My best 60' of the day was 1.849.
