When I use the O/D button on the shifter my O/D does not work..........most of the time. Fired up the SC this morning and started down the road like I do most mornings. Pushed the O/D button and the O/D came on and held the tranny in 3rd. Drove for about 5 miles and pushed the O/D button to go into O/D. Nothing happened! So, like I have for the past 3 months, I pulled the shifter very slightly back toward 2 (the tranny does not go into 2nd gear) and pushed the O/D button. The tranny shifted into O/D. Then for the rest of the day I have no control over the O/D. I can push the button all I want and no O/D green light shines or shift is felt. The tranny shifts up and down great. I use Royal Purple synthetic tranny fluid. I also installed a TransGo shift kit and a ProTorque 2500 stall speed torque converter before the O/D problem started. However, the tranny worked fine after those 2 mods and the O/D probelm just got worse over time to it's current state. Anyone else been lucky enough to have this problem? If so, how did you fix it?
My prognosis is I suspect the 3-4 shift valve works OK when the fluid is cold and sticks or the coils fails when the tranny fluid gets hot. I have no CE codes. Any help would be appreciated!
