I know its the Governer Pressure Solenoid. Told my dad to have them replace the GPS, and the Governer Pressure Sensor, just in case. AND MAKE SURE they put ATF+4 in. I wanted to check his TPS, but couldn't get a good reading on anything. I know on the ZJ its the middle wire, and to check with key on engine off. Is it the same on the WJ?
Here are the symptoms...feels like its pulling out in 2nd sometimes 3rd gear. And it just had a transmission flush, which I understand could stir up some debris and cause this problem. Any other suggestions?
