In 2006 I purchased a 2004 5-speed manual shift Nissan Xterra 4x4 with 19k miles on it, it looked and ran like new.
I live in Florida, during the Summer of 2010 I noticed that when I accelerated from a standing start (like at a traffic light) as I shifted through gears 1-4, at some point the RPMs would rev up but the car was accelerating very slow. The only time this doesn’t happen is in 5th gear or in 4WD-high or 4WD-Low. This problem is not consistent, it happens occasionally but enough times that I’ve had to alter the way I accelerate to avoid this problem, ie accelerate very very slowly.
I have taken my Xterra to my local Nissan dealer, twice, they cannot replicate this problem no matter what they do; drive it cold, drive it hot, fast, slow, cold weather, hot weather, no matter, they can’t replicate the problem.
I have read here and there on the 'net (we all know the 'net never lies) that the transfer case on 4WD’s can act squirrelly or could even be a simple case of replacing the transfer case fluid.
Anyone have any idea why this “slippage” is happening and how can it be fixed?
This is of concern only because if I have to accelerate hard (like when a locomotive is looking to T-bone me) I’d like the Xterra to get up and go rather than pause and reflect over the lilies of the field while Thomas the train is bearing down on me.
