Intermittent Reverse and 3rd Gear poblems
Took the pickup into a shop because it shifted up and down, couldn't make up it's mind. The shop put in a new "updated" ICP sensor, now the pickup does not have Reverse and 3rd gear. Sometimes it works and sometimes it doesn't. When Reverse is not working you can force it by revving the engine and building pressure and it will go. They also stated that when they pull the electrical harness to the tranny, Reverse works. When the pan was pulled, fluid is nice and pink and there is NO debris in the bottom of the pan, yet they state they have diagnosed everything and I need a new transmission. I am questioning this and would like to hear what some of you would suggest.
