    Transmission issue

    in 96-2004 R50 Pathfinders

    Posted

    After a two hour rest break today the automatic transmission on our 99 Pathfinder suddenly started to act up.   We tow a small travel trailer.  Transmission temp was about 150F and engine temp was normal.  ATF and filter were changed earlier this year.  Would not shift into overdrive and the torque converter would not lock.  Revs were about 1100 higher than it should have been.  Drove for about 10km and then stopped.   The check engine light did not come on but I ran the diagnostic computer anyways.  There were a few stored codes from a couple of years ago (02 sensor, evap and knock sensor) so I cleared them.  Got back on the highway and everything was fine for the rest of the day.   Seems very odd.

     

    Any idea what is going on? 

    Weird wobble

    in 96-2004 R50 Pathfinders

    Pressed in 4 new Nolathane poly bushings in the lower trailing arms.  The Moog ones were shot and only lasted about 35,000 KM.  Disappointing.  Problem is solved now.

     

    Pressing out the old bushings was extremely difficult.  Even with a 10 ton press we could not initially press out the bushings.  So we made several cuts in each the bushings with a hacksaw and then used a chisel to peel away part of the shell.  Then back to the press.  Is there an easier way to remove these bushing?

    Thank you for the quick replies.  When the original trailing arm bushings were shot I didn't have this problem.  I rechecked all the bushings a couple of days ago and they appear to be in good condition.  Panhard rod also appears to be fine.  Same with rear end links.

    Since about last summer my 99 Pathfinder (4wd) has developed a weird wobble to the left whenever I let off the gas at highway speeds.  When resume speed it wobbles to the right.  Quite annoying.  I know it is not the rear trailing arm bushings as those have been done.  On the front end I've done ball joints, inner/outer tie rod ends, struts and coils and end links.  The rear also has new coils and shocks.  Alignment has been done.  Engine and transmission mounts appear to be in good shape.

     

    Any ideas are greatly appreciated.

    Ignition skipping.....

    I am stuck a thousand miles from home with the P1336 code. Vehicle runs well when cold but then starts to act up as per the original description in this section. Waiting for a new crank sensor to arrive. It seems strange that this sensor is not required to control the engine. Other vehicles won't start without a crank sensor.

     

    Is it a given that the distributor will have to be replaced as well or are there other likely culprits? Any suggestions are greatly appreciated.

    Brake bleeding problem

    in 96-2004 R50 Pathfinders

    Installed new bleeders on the front brakes and then did another round of bleeding after cycling the ABS on a dirt road. The steady stream of bubbles stops when we hold the bleed jar up a bit. Very strange.

     

    The brakes are still the same. Double pump every time for the best braking.

    My 99 (4wd) has always required a double pump of the brakes since I got it a couple of years ago. Today we used a pressure bleeder and got air out of 3 brakes and the load sensing valve, but cannot get all the air out of the front passenger side caliper. There is just a constant stream of bubbles that never end. We have used 2 quarts and most of this has gone through the last brake. The FSM makes no mention of bleeding/cycling the ABS unit.

     

    Any suggestions?

    Rear suspension noise

    Thank you for all the great suggestions!

     

    Found a few loose bolts underneath the back end. One sway bar end link had a bit of play so I removed it. Checked the spare tire. Tightened the loose bolts and did a road test every time I tightened/removed something. Still lots of clicking/rattling. Frustrated, we decided to just walk around the vehicle and push each corner side-to-side and up and down to see if we could reproduce the noise. To our surprise, we found the clicking/rattling noise at the front driver's side. I'm betting it's the sway bar end link. Ran out of time to check how tight the nuts are. I replaced both front end links in the spring, but perhaps they've loosened up a bit.
