We have an 08 Quest “base model” (doesn’t have a S, L SL or any letters after it, really a base model LOL). Owned it since new, and it’s been a great vehicle.
How often should the transmission be flushed and the trans filter be replaced on this car, if at all? Ours has 74K on it, and the service has never been done. I can’t seem to find any info on it in the manual (manual says things about CVT trans, this one is a 5 speed), and my mechanic seemed clueless. There is a trans specialist in town, he’s a great guy who has done work on many of my work and personal vehicles over the years, but I wanted to see if anyone here knew the answer first.
Also, yesterday when I went to get dinner, I started the car, and it took 3-4 cranks to get the car started. When I accelerated, it seemed like it was stuck in one high gear (low rpm, virtually no power, even when floored). Got to a traffic light and it stalled… cranked it back up, and I had to keep revving the engine in neutral for it not to stall again. No lights came on the dash. Got it home, ate dinner, started it back up, and drove it around town. This time it drove perfectly fine, even on the highway. went through the gears as normal, good power, etc. I have been reading about crank and cam sensors… is that likely the issue I’m looking at?
thanks for the help,

You might have a bad Camshaft Sensor or both. Easy fix and you can do it yourself. Look for a OEM part online and you can buy for about $50 each. Dealer is about $125 each. This might fix your problem. Replace crank shaft Sensor also if possible.January 21, 2016 at 5:22 pm #10582
Get an OBDII sensor and pull the codes first, don’t just blindly replace expensive parts! The codes may just point you in the right direction.January 21, 2016 at 8:12 pm #10591
Yes, OBD II sensor will narrow down the problem to 5 or 6 possibilities. The only correct diagnose is supposed to be at the Dealer who has a factory diagnosing machine. Even that in my case was a wrong diagnosis. Dealer said I have to replace just the two secondary chains (in a Timing chain issue), secondary tensioners and the guides. The problem was the main guide and tensioner. My scanner gave 7 possibilities from a car specific code. Dealer had to fail Emissions 2 times but DEQ would not pardon the vehicle. I Had a white elephant at home with no emissions and no registered tags.
The symptoms above directs me to my conclusion as I did a thorough research even with Nissan USA. After market 2 sensors would not undo the SES light and only the OEM parts did the trick.
