#20 of 23 2008 Scion xB Automatic Transmission Problem by ds329

Aug 10, 2011 (7:09 am)

I have a 2008 Scion xB. The automatic transmission will not shift from 3rd to 4th gear. Took it to dealer and they indicated that it is because of the Knock Sensor. The Knock Sensor issue showed up when they checked the "Check Engine Light". I knew about the Knock Sensor, as I had my local mechanic check it out before taking it to the dealer. However, I had spoken to a couple of other mechanics and no one can understand how the Knock Sensor is preventing my transmission from shifting from 3rd to 4th gear. I never would have known there was a problem if I did not drive on the highway. On the streets, going less than 45 miles per hour, you would never know there was a problem. My gas mileage had suffered greatly and whenever I fill up, the "Range" light indicates 254 miles instead of the usual 323 miles. So I am losing about $15 every time I fill my gas tank.
 
Any thoughts?

I had the exact same problem with my Scion which is also an 2008 Automatic Scion xD. The code read something was wrong with my transmission, and I was not able to go into 4th gear which was using my gas faster. Wires to the code reader had been chewed by rodents (rabbit or squirrel probably). It was hard to find but a simple fix. Be careful because some auto mechanics might sell you a new transmision for this.

Thanks for the reply and believe it or not, it was the exact problem you described. However, when I first took it to the Milford, CT Toyota/Scion dealer, they never mentioned the rodent/mice issue. There was debris left by the critter and the wires had been chewed through. The Aamco transmission place never mentioned this either and told me it might cost up to $4,000 to repair. My son finally took it took a local mechanic near his job who did checked it out and told him the real problem. I thought honesty was something that you could take to the bank with Aamco or even the dealer. No such thing. Thanks again for the information.

Its of dude not if you idiot, and that clutch should last 150k. Additionally scion clutch assemblies arent very good because mine sometimes will not shift or get hung up in between gears for no reason at 30k
