Hi all, I’m having a problem with my 94. Tranny is freshly rebuilt. My problem is getting it in overdrive. Before the rebuild it started acting up along with the torque converter lock up so I put them both on ground switches and ran a 12volt wire to the plug. Which by doing so I’ve bypassed the pcm and all the sensors. I still only occasionally have overdrive. The lock up works fine no problems. I do have both switches ram to the same ground in the cab, but was going to move the overdrive one to the battery. I also bought a new plug and put in new solenoids. I used the plug from the patc website and it says oem, but seems to snap into place good. Any ideas would be much appreciated.
 
Put a pressure gauge on the od port and see what your getting. Once you figure that out we can go to the next step
