TS 6 position chip issue

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-
Jimmy Mac

Jimmy,
It sounds like your chip may have a different code on it than what your truck has. Give us a call at TS Performance and we will see if we can help you figure out the problem.
