Hi, I recently swapped a 47rh transmission into my '93 Dodge 1 ton, behind the Cummins. So now I have a lockup torque converter. I am operating it with a toggle switch on the dash. I thought that would be no problem but I ran into a situation where it was. Somebody pulled out on me when I was doing about 60 MPH and I had to do a panic stop. Jamming the brakes, steering the truck, just paying attention to what was going on, I didn't hit the switch to unlock the converter and it pulled the motor way down. It was like driving a manual transmission truck and not stepping on the clutch.
I have heard that there is a way to wire a pressure switch in series with the toggle switch so that the torque converter will unlock at a certain mile per hour.
Can anyone clue me in on what switch to get, and where to screw it into the transmission? Thanks, Joel
