2004 Mystery Switch with Pedal and Pressure Switch complete and WORKS!
 

I finally got around to installing my "Mystery" Switch.

I found a nice pedal switch at Harbor Freight for like $10 or so. I cut the cord off and rewired the internals. Then I used the cord plug for the "out" connection. Real easy. Mounted the pedal on the floor up by the e-brake pedal.

I installed the Hobbs pressure switch that I mentioned earlier.

I decided to do the relay mod instead of the resistor. I pulled the trans relay (#59) and put a small wire, wrapped onto each pin of #30 and #87. Pushed the relay back in place.... no solder required.

Works like a charm. I can hit the pedal at a stop. It will lock up as soon as it gets to about 10-15 mph. Anytime it's chugging more than I like I just hit the pedal once more to unlock.

Downshifting is not pleasant. I turn it off as I'm slowing down. I see me using this more for pulling my 10,000 lb trailer up the steep hills to keep the trans temp down.

That's pretty ingenious, and keeps the hands free at the same time.

Nice thinking outside the box.

Thanks..... yea I really miss the old floor mounted high beam switches.

I think I'm gonna coat the PosiTap connector with liquid electrical tape to make it waterproof.

Next I gotta install my air bags. Gonna do some camping this year with the new (used) trailer I picked up last year.

I pulled it last fall right after I got it. What a big surprise. Now I know why people get manual trans. The trailer is 10,000 lbs loaded. I wasn't loaded. Up some short steep hills I needed lockup real bad because the trans temp was going through the roof. I don't know how Chrysler expects this trans to live pulling it's rated capacity up hills. Fluid was hitting 300 deg coming out of the torque converter. Trans temp gauge and a lockup feature is a necessity. Tow haul doesn't help if it doesn't get out of second gear and it still didn't lock in third cause I wasn't going fast enough.

I changed the filter/fluid last week. Full flush by disconnecting the rear line. Fluid didn't smell but was discolored. Just wasn't the bright burgundy of the new stuff.

This is a Goerend trans with about 15,000 miles on it. First fluid change. Very little debris in the pan. Basically just some real fine fuzz on the magnet and nothing at all in the bottom of the pan. I was really happy to see that.
