Judder while downshifting (Safari 2.2)

Of late I've been facing this problem of a judder (for a split second) when I downshift from 3rd to 2nd (speed @ ~ 30 kmph & RPM near idling).This is not a consistent behaviour and happens every now and then.
Am I doing something wrong here ?

Also when I accelerate in 1st/2nd gear,I can sense slight engine movement as if the engine mounts are absent and the engine has been tied via ropes or something ;-))

Any ideas ?

Thanks,

get the mounts checked, you could be having a busted engine mount.

The car has only clocked ~ 5000 kms in two months.You think the mounts can go kaput in this short span ?

should not happen for about 50K kms but sometimes can happen unexpectedly.

In my case (1990 Nissan) the original mounts were there for over 8 yrs (thats since I know the vehicle - the mechanic said these are originals) until the left side got ruptured probable cause could be due to high prssure power steering hose ruptured and oil on the mount.

checking mounts need a technical eye - can be seen with hood open, look at the mount and ask someone to start / turn off / start / turnoff ignition you will notice engine movement forward backward on a defective mount. easy on rwds

The mounts are damn expensive and since your vehicle is new should be under warranty get it checked / changed.

Driving with a broken mount has very serious effects to the exhaust system especially the rubber hooks, clamps which will snap and worse it may tend to break at muffler joints.

---Experienced in an old (much older than T-BHP abbreviations, in fact the original) Civic.

Replaced exhaust due to general wear, but the new one broke at the manifold. When I went back to the fitters they dug a little deeper and found the reason to be worn out engine mounts. They replaced the part under warranty, as they had failed to diagnose the problem, which was decent. Of course, I got the mounts done first.

But that was a fifteen-year-old car!

I've observed the engine movement.It is more on sideways rather than backward/forward as you mentioned though not too violent
