[QUOTE="Coolit, post: 1539142, member: 32093"] I just noticed today after driving it for a little bit without the chip in it will start coding/ flashing the overdrive off light I'm not able to scan it because as soon as i get down to 10 mph the overdrive off light stops flashing or while it's flashing if i kick it up in neutral and shut the engine off and restart it it turn off and does fine when it starts to code it is constantly going in and out of what seems like is overdrive but it's 3rd and then sometimes it goes into overdrive and 25 mph and it making lockup on the Tc, it's doing all kinds of crazy crap I get a good 1 - 2 shift then everything goes haywire but only when it's warmed up good. I hope all that makes since I know I shouldn't be shutting my engine off running 55 mph down the road but it's a long straight road and sometimes ya gotta do what ya gotta do lol. I'm starting to think I have a bad speed output sensor or on it way out completely at some point my theory is with the chip out the sensor works good enough until it gets good and warm the codes but with the chip in it's weak enough the chip just causes it to code as soon as it shifts 1 - 2 then codes I don't know I'm just guessing at this point I'm just glad there's folks around such as yourself to helps us numbskulls out that don't have a clue as to what we are doing. Thanks for the help I really do appreciate it [/QUOTE]
