TCC switch in 46RH location?
I have a 92 Dodge 3/4 ton w/ Cummins 12 valve and I believe a 46RH auto transmission. I was trying to figure out where the TCC lock-up switch is in the transmission to clean it. The problem is the truck shifts in and out of overdrive going highway speeds. If anyone has any other ideas, it would be most helpful. Thank you for your answers and opinions in advance. And this truck did come with this tranny model, correct?

that's not the tcc switch that's making it go in and out of over drive ,over drive is 4th gear on it and that transmission has lock up converter on it,the switch your looking for sets above the valve body on it so you have to drop the pan off to get to it,you need a repair manual because you may get in to more than you can handle on this one,its not as easy as we make it sound sometimes,good luck on it.

Should be a vehicle speed sensor on the end shaft of the trans or transfer case, that may be bad, the connectors at the sensor, or the engine to trans connector near the firewall may have a bad connection, clean every ground from the engine, trans, body, and battery, there should be a strap near or above the starter, maybe on the rear of the head. Use sandpaper. And make sure the gear on the VSS is ok. The lock up sol. is usually on the valve body, and the lock-up is inside the converter stator. If you need a schematic, need year, and the size of the engine. the overdrive is a 46RE. now
