Mike's 1993 Dodge Cummins Truck Blog

So I have been researching in the Cummins forum for info on the transmission. It’s basically a 727 with overdrive. The tps or throttle position sensor is used to tell the transmission when to shift into overdrive. As it turns out my transmission works fine as long as the overdrive is shut off. I found that several owners had taken out the factory tps and put in a pot that mounted to the dash. This seemed to fix many of their overdrive issues. So this morning I took off the tps and found that it is not being turned as the throttle is moved. The female hex on the throttle shaft was a bit damaged. The adapter that connects the tps to the throttle shaft is adjustable. I made sure the tps would rotate as soon as the throttle was touched. That cured the overdrive issue!!! Now it shifts into overdrive right around 35mph just as it’s suppose too!!!

Jackie and I saw wasps flying into the vents of the truck. So I found that the vent grille could be removed. Once I got it off and used a mirror, it was very clear there was a large wasp’s nest up under there. I bent up a piece of music wire and began scrapping the inside of the cowl area for the nest. Of course we were dive bombed by wasps during this sortie. I gave Jackie a spray bottle to fend off the wasps with. It worked great!!! Here is what I dug out of the cowl. My sunglasses are there for scale.

Today I showed up at dmv at 7am thinking I was an hour early. Turned out they opened at 9am on Wednesday’s. So I waited for 2 hours. The fees were $200 total. The truck was now mine!!!! No smog required!!
