99 Rx300 With P0500 "vss Vehicle Speed Sensor"

[android0103]

Today is March 14th, 2010. I own a 1999 Lexus RX300 with only 21,000 miles. I recently got a "check engine light" so I stopped at AutoZone for the free scan and got "P0500 Vehicle Speed Sensor". For the past week when I first get in it for the day. The transmission shifts at 3-4000 rpm.. much later than normal. It only does this for the first shift out of first and sometimes second gear. After that everything shifts normal. The check engine light will stay on for anywhere from 1 hour to 1 day, go off, then not come on for another 3 days, then suddenly there it is again.

I know that there are two VSS's. From what I have read, if the speedometer is not working, it is the sensor with the 3 prong connector that is bad.

The one that looks like this ----> http://shop.advanceautoparts.com/web...980-_-10720525

Since my speedometer is working perfectly, is it the sensor with 2 prongs that I need to replace? The one that looks like this? ----> http://shop.advanceautoparts.com/web...980-_-10720525

Thanks so much in advance for any help! I'm assuming if I get the correct information from this forum and I'm able to replace this myself, I will same myself several hundreds of dollars!
