I want to purchase a 2005 / 2006 Nissan Quest. But a friend told me not to. He didn’t give me a reason good enough not to. Please house, I need your suggestions on this

If foreign used go for it. If Nigerian used stay out would have been heavily brutalized. Had one came in to my workshop last year. The reconfiguration of wires she had would even be hard for nisssans themselves to comprehend

The 2004-2009 Nissan Quest has a 3.5L VQ engine mated with two transmission types. One is 4-speed produced by JATCO (owned by Nissan) which was used on models between 2004 and 2006. The other is 5-speed produced by AISIN AW (partially owned by Toyota) which was used on models between 2004 and 2009. The Aisin AW transmission, known as RE5F22A, is also used in the Maxima (2004-2006) and Altima (2005-2006). Unfortunately, the valve body in this transmission appears to be underpowered to run high hp generated by the VQ engine. The 2004-2006 Maxima, with 265hp@5800rpm, became most infamous for this defect. The 2005-2006 Altima, with 260hp@5800rpm, became unpopular also though not as much as the Maxima. The Quest did not so much experience these transmission issues. Here’s why:
2004-2006: 240hp@5800rpm
2007-2008: 235hp@5800rpm
2009: 230hp@rpm.
The fact is Nissan got wise after 2006. They discontinued the use of the REF522A transmission both for the Maxima and Altima and progressively reduced the hp in the Quest. In sum, the transmission was more successful in the Quest for the obvious reason that it had a lower hp. If the Quest you are proposing to buy is 5-speed there’s a possibility (not certainty) of a valve body issue later. But then if it’s a high mileage car the issue may have been addressed by the/a previous owner.

Hearing this for the first time - valvebody mishandling torque in REF522A? How is that?

GAZZUZZ:
schmoopiesecret I hope you are reading? When motor get long tory like dis you have to be careful.

Costee:

There's always a first time . But seriously, I don't think it's coincidence that from 2006 when Nissan dumped the RE5F22A for their own CVT transmission, the hp in the three cars has been on corresponding increase. That in the 2017 Maxima has gone as high as 300hp@6400rpm; the last time there was a 3.5L Altima was in 2012, and it had 270hp@6000rpm; the 2016 Quest has 260hp@6000rpm. I just can't run away from the hunch that the VQ preferred to relate with the RE5F22A at some lower level.
PS. An updated version of the valve body was released from 2006.

Kashif:


My point is - it is better to tune the power down, than updating VB. The update in the VB must have been for something else, not power handling.

Costee:

Isn't this my original observation, which you queried? At any rate whatever defects there are , are usually manifested in valve body failure.

Kashif:


What were the complaints, and how was it determined to be caused by inadequate power handling capacity of the transmission? Any TSB?

Are you saying that the 4-speed produced by JATCO is better and secondly, how will I know it's a 4-speed
So you finally understood the lecture. The term better is relative here depending on the state of the car you're proposing to acquire. I was only trying to draw attention to a likely hitch in the 5-speed. Check the label on the driver's side door pillar or the engine room for the type of transmission. If it's RE4F04B it's 4-speed, if RE5F22A it's 5-speed.
