Code P0717

Thanks for the test parameters. The picture is the pickp end of the bad sensor. My concern is the potential amount of material that seems to have rubbed or broke off the end. I could hear a faint noise that sounded like a heat shield rattling but inside the tranny near where this sensor came out. Any recommendation as to dealing with any plastic or metal that may have gotten inside. When I find the correct sensor I'll have a better idea how much was missing off the old one. I'm also drawing a blank on how it broke the end like that. It's not supposed to touch.

Well I put a new sensor in and the car started normal and as soon as I put it in gear the tinny sounding rattle stopped. I drove it and it shifted from first to second gear but as soon as it hit 20 plus mph it disengaged and the engine revved. Below 20 and it would pull it down the road. After test drive I pulled the new sensor and it was destroyed like the original one.
I got a used one from another transmission and put it in with maximum amount of spacers and it didn't read it. I dropped it down one spacer and it wanted to run better (almost 30 plus mph) but wouldn't shift into third gear. At 30 it disengaged. At that point I pulled both speed sensors and found the input sensor (short one) still physically in good shape but on the output sensor (long one) now had a slight scrape mark across it. Also there was a bit of metal shavings on both. More on the input sensor. My daughter and I looked at eleven CRV's before we bought her this one (it's her second one) and we both thought it seemed to shift smoother than all the others. Do I need to replace this transmission after she's only drove it 3,000 miles in the three months she's had it?

The original input sensor that came with the car was found damaged when the problem 1st happened. The 2nd one I purchased from Honda (part#28820RWE003) came up damaged in the same manner as the original after driving a few blocks. The 3rd input sensor was installed with spacers that weren't originally there and came up undamaged but still no signal code P0717 and an additional code Intermittent Signal P0718 which wasn't there at all before. I'm thinking that was because the spacer had it too far back from the tone wheel. New to the equation was the original output sensor (the longer one) had a scrape mark across it. Not as bad as the other and not all the way thru the plastic. I'm thinking that the tone wheels are wobbling and giving intermittent readings and destroying the sensor when it's set at the appropriate distance from the tone wheel. How else could what was a working set up for so long suddenly start eating sensors? Is it heard of for the tone wheels to spin off its axis like that?

So either way the transmission has an internal issue and needs to come out probably replaced. Do you agree with replacement?

With that much labor involved to dissect the transmission it would be better to just replace it. Thanks for the help.
