So the pressure switch activates the lockup based on the pressure in the transmission? I'm terribly unfamiliar with how lockups are controlled. Curious also how the overdrive one works.

When you don't know what you're doing, it's best to do it quickly.

And when Iím gone, you can call me foolish but hopefully not boring. I will have lived.

The more I learn about women, the more I like my car.

Great minds think along the same lines I guess.
I've even put them on the lathe and turned them down to fit different applications in the past.
Not to mention they are cheap.

The only thing that is electrically controlled in a 518 46RH Dodge transmission is the over drive solenoid and the torque convertor lock up.

Instead of controlling them through the ECM, which I did away with, you can install the the 2 pressure switches in the pressure port. One is a 48-50 psi for the over drive clutch. I like the 50 psi so it engages at 50 to 55 MPH.
The other is to lock up the torque convertor (52 psi) after it shifts into over drive.

I've used this set up in 4 builds with great results.

You can do away with the pressure switches by using toggle switches and engage them manually if you're so inclined.

Most guys I know with lockups in hot rod have them on a switch, which I find pretty clumsy. This sounds like a much more elegant solution. Thanks for explaining!

We went to our friend Linda's "celebration of life" today. Still a funeral to this old guy.

Eric and Linda were the best friends in our lives and meant a lot to us. They will be sorely missed.

It still blows my mind that they both died with in 4 months of each other.

I had to do some thing other than think about the woes of life so back to the shop....

I got the drive shafts installed-again. Then it was time to snake the exhaust into place. I had to modify a stock cross over pipe to clear the starter and go around the front drives shaft. I was able to keep it above the bottom of the frame rails so it should work.

Now to clear the three cross members. Right now there is no clearance over the top of the 1st one. After the cross members it will a piece of cake to install the muffler and tail pipes. It's all fun and games.

The good thing about exhaust work is it comes toward the end. I agree with OI.
