Just installed my 6 position chip into my 99 PSD 7.3L
When I turn the truck on the overdrive light on the shifter column flashes off and on.
When I put the truck in drive or cycle through the gears it goes off but I am unable to press the button to manually and can not engage the overdrive on my own-
Anyone familiar with this problem or know a fix?
Thanks-
