Pathfinder Jerking

[graptemys]

Hi,
I have a 99 Pathfinder 4 x 4 XE that now has 195,000 miles on it. I am having a problem. Sometimes when I accelerate the vehicle will jerk for a split second. It appears that it loses power while accelerating for about a 1/2 a second and then catches up so that is where the jerk comes from. Does anyone have any guess as to what might be faulty... the transmission, fuel pump, etc? This never happens while I am coasting. It only happens when I accelerate and it only happens once or twice in a 5-10 mile drive... for now.

There are no odd noises or other symptoms.

sounds like a transmission issue. Fluid flush might do the trick, have that checked out.

Definitely your transmission. Sounds like it's slipping and needs to be rebuilt. Of course you could try a junkyard tranny, but that might cost you as much or more in the end.

When was the last time you replaced the fuel filter?
