O/D off light on, help!
So i recently purchase a 2003 dodge durango, has a 4.7l V8 in it. It has 65000 miles on it.
Well heres the problem, when i bought it i was driving it, and it was all good, i stop'ed some place and was just testing all the stuff ya know, hit the o/d off button at the end of the shifter and nothing happend, no o/d light off light or nothing, so im like hmm, maybe there has to be some other circumstance for it to be on or used. Like if proper conditions not met wont let you override the overdrive. Drove it home witch was like a 60mile trip. So had it parked for a day, was the weekend had to transfer title insure it and get new plates (wife wanted the pretty plate with habitat stuff on it) So she gets in it on monday and im in the passanger seat, and i look over and the o/d off light is on, and im like wtf, and hit it to see if it would come off and nothing happend (maybe it can be engaged or disengaged while its in motion or in gear?).
So my wife parked cause i told her to put it in parked turned the truck off, turned it back on, light was still on, hit the o/d off button and it turned off and on our merry way we went. Than about 15 min i looked over at the dash and bam, light was on again.
And i noticed, that it would be on, and then if we parked for a while got in, the light would be off and after driving it for alittle bit the light would turn back on, you wouldnt feel the car shift or nothing, it shifts normally and everything but ive been reading that you can feel it or hear it or somthing shift out of overdrive, when the light is on nothing happens that isnt normal, shifts very smooth still, everything seems to work fine. Also been reading that its usually followed by the tranny temp light and check engine light, but this doesnt happen, granted we have only been driving it a day or two and only put on like 120miles since we bought it.
Now my questions are possible fixes, should i flush the tranny and go from there? should it be ok to keep driving it? how can i get the temp of it without the fancy equipment like obd readers.
sorry about the run ons and errors but im at work trying to type this up quick.
