You got a problem a sense on the accerlator .Or on the air intake senser.If it's not that I would put gas cleaner in the tank.That would be the cheaps thing to try. Buy your gas at walmart and in the insle that has the tech gas cleaner and buy it there ,it will install it has you pump.

Hello you will need transmission repairs sometimes when a filter and fluid is changed when a scheduled maintenance has not been followed by owners manual you might have trouble as you do believe it or not sometimes when you exceed the suggested service millage you better off just to leave it and do not service or you can experience trouble as you are having.My solution is take your vehicle in to a transmission specialist you will need a hoist to determine the extent of your repair you might have to rebuild your transmission.

This is known problem with Nissan pathfinder.There is no actual recall called by the Nissan service center.But this problem is faced by many other Nissan pathfinder users too. ------------- The reason for this problem transmission failing.-------- First get the transmission fluid inspected.If it its dirty then replace the transmission fluid.------- In this problem the radiator fluid fails into the transmission, causing both the radiator and transmission to fail. The antifreeze to observe traces of transmission fluid. Checking the transmission fluid, the fluid gets darken and above the high-level mark for the fluid level. ------------- The problem occurs due to radiator getting failed, leaking coolant into transmission which required both to be replaced. Transmission failure is an obvious safety issue for many reasons. The loophole appears to be that since the failure is due to the radiator, anything relating to the transmission is null and void.--- ----------- Click this link below to get more details about this same problem faced by other nissan pathfinder users:--- http://howtobyme.blogspot.com/2011/08/nissan-pathfinder-shudders-around-60.html ---------- This will help.Thanks.Helpmech.

It must be giving you a code as to what is going on here. It sounds like you have a bad silenoid to me. It will be inside ya trans on the valve body. Check and see what codes are comming up on it.
