In owners' own words
Coolant fron radiator entered transmission causing shuttering. Vehicle was brought to Nissan for repair. Engine coolant had entered the transmission causing failure to transmission.
Hello fellow "Nissaners"! Well, was so happy with this truck and my wife as well, because that was her first idea to purchase this good-looking vehicle.
Transmission/radiator failure resulting in mixed transmission fluid and coolant. I have just discovered this since I was having transmission problems.

Recalls for the 2006 Nissan Frontier: 7
The intelligent power distribution module (Ipdm) assembly contains an engine control module (ECM) relay that has a diode for electrical current noise reduction. This could cause engine stalling increasing the risk of a crash.
The lower control link assembly has two cylindrical collars forming the inboard attachment points to the chassis. Due to an improper welding process some collars may contain welds that do not meet strength specifications. If the collar weld separates, the vehicle handling will deteriorate, possibly resulting in a vehicle crash.
The molded fuel tank shells can deform, causing the fuel sender float arm to contact an embossment molded into the tank shell causing the instrument panel fuel gauge to show that the vehicle has approximately one quarter tank when the fuel tank is empty. This could cause the vehicle to run out of gas and stall in traffic, increasing the risk of a crash.
In those areas of the country which use heavy concentrations of road salt in the winter, a mixture of snow/water and salt can enter into the front crash zone sensor (Czs) housing. If this occurs, the czs may internally rust resulting in a signal interruption. This issue could result in the non-deployment of the driver and passenger front air bags in a crash, increasing the risk of personal injury.
Certain hopkins aftermarket trailer brake control connection harnesses sold for use on certain models of Nissan vehicles which are listed above. The internal part numbers within hopkins are: 1010476025, 1040376025, 1110476025, 1170376025, 1290376025, 1010476035, 1040376035, 1110476035, 1170376035, and 1290376035. This harness would result in power from the trailer brake controller going to the towing vehicle dash light circuit rather than the trailer brakes.
Certain tradesonic combination lamps sold as replacement lamps for use on the above listed passenger vehicles. Combination lamps not equipped with amber side reflectors fail to conform with the requirements of federal motor vehicle safety standard no. 108, lamps, reflective devices, and associated equipment. Lack of amber side reflectors in the lamps will decrease lighting visibility to other drivers and may possibly result in a vehicle crash.
On certain king cab trucks, in a severe side impact crash, there is a possibility that deformation of the vehicle's body could cause the fuel filler cap tether to be stretched to the point of unscrewing the fuel filler cap. This may result in a fuel spill which in the presence of an ignition source could result in a fire.
