Hello eh,
I have a 1993 Nissan Pathfinder V-6, 4x4, with 230,000 kms. The problem occurred as I left a yield, I stated to move, then as I went to pressed the gas and gain speed, I noticed I was not accelerating. No smoke, overheating, leaks, nothing, none of the dramatics (slipping, leaks, burnt smelling fluid, etc.)
I coasted over to the side and checked the fluid, it looked and smelled good, then looked underneath no leaks, Tried all gears but would not engage in any gear, including reverse, so I shut her down and had to get it towed to my house.
What could this be?

Something electrical or mechanical? I have read this could be the result of a line pressure solenoid valve, true? How much $$$ to have this replaced? Or a tranny oil pump? I bet that will hurt the pocket book to replace. I have tried putting it in 4WD with no movement either? Fluid level was fine with no signs of degradation.
Any advice is greatly appreciated
Cheers
