RX won't move, codes say speed sensor
 

Is THERE A WAY TO DIAGNOSE MY RX300. IT MIGHT BE TRANNY BUT CODES SAY SPEED SENSOR BUT IT JUST WONT MOVE. IF THERE IS A WAY TO FIND OUT WHATS WRONG WITH IT DOES ANYONE KNO WHAT THAT MIGHT RUN PRICE WISE? I WOULD HATE TO PUT ANOTHER TRANNY IN IT AND IT BE NOT THAT!! I MEAN NO TRANNY CODES NO TRANNY ISSUES EVER. THANK U

What does "won't move" mean, and what is the exact code

We hear you.

Can you roll the vehicle in "N"?

ECU codes are typically emission related and overdrive not engaging is the only transmission code that pops up when it fails to engage overdrive [speed greater than 50mph].

Any update on this? Has it been fixed?

Cjheck if you a roll the vehicle in "N". This will eliminate brake lock up etc. All symptoms point to a transmission failure .
