Pajero Owners Club of South Africa

Hi all,

I've been reading these forums for a while but never needed to post until now.

We own a 2004 3rd generation Pajero with the 3.5 GDI and auto transmission. In general it runs and drives beautifully, with one exception: under any load (mild acceleration or maintaining speed up a hill), the entire vehicle shudders like it's going over rough pavement or corrugations.

This does not happen under heavy acceleration because the auto box moves it right past the 1400rpm mark. Neither does it happen while cruising at any other engine speed. If I use the manual gear selector to increase the engine speed (i.e. Downshift one gear from whatever the auto has selected) the shuddering disappears, but at the expense of fuel economy.

I've had 2 different mechanics look at it, and neither can give me an explanation, so I'm seeking your collective wisdom. Also posting this in the drivetrain forum.

Thanks!

Had a similar issue, there was a vibration under any load (idle or cruising) between 2000-2100 rpm which was very annoying when driving at 100Km/h.
Searching the forums I found out that the trans mount rubber changes its flexibility over time and makes a resonance at that engine speed.
Advises were either to change the mount or removing the dynamic damper (which is a 3Kg weight mounted at the end of the transfer case) to change that resonance.
So I tried it with the cheaper solution and most of the annoying vibration is gone now.
You can start by removing it and see if it makes any difference.

Thanks!

I like solutions that don't require buying stuff. I'll see if that does the trick.
