The right engine mount has failed and it will have to be replaced. This is a job for a shop, the engine must be lifted from the chassis to access the mount.
It's a 2 day job so make arrangements for a replacement car.

    Which engine mount would you think it is? Is there one at the top and bottom? Thanks

    The top one, it's only it on the right side .

  • Guy wolfenden Oct 07, 2013

    Changed this and the problem is still there? Any more sergestions?

    Check the transmission joints. BTW i've assumed that the noise comes from outside the engine, if it's the engine itself the one that knocks then you have a problem with the ECM, it doesn't trigger the ignition correctly.

SOURCE: knock sensor

Yes!
Same problem with my car, won't shift especially when cold.  I was told that if the knock sensor is sending a false signal to the computer that the engine is pinging then it will not allow the transmission to shift until the pinging stops.  Other people have had this problem too, check out this link, especially the last entry:

Car is in limp in mode unless you have the tools to work on automatic transmission you will need to take it to a transmission shop. Of course you can check oil level but I suspect you have other issues.

SOURCE: Hi My jeep cherokee 2.8 crd has knocking sound

Well, something is broken. I suggest that you get it on a lift, and listen with a Stethoscope and be sure the noise is in the tranny. There is not usually anything good that comes from a noise like you describe. A broken tooth on a gear damages the mating gear and those parts add up fast.

It sounds like you might have a bad busing in your shift linkage. The run from the bottom of your shifter to the transmission check those bushings and make sure that everything is in place under your shifter. Hope that helps you.

Whining noise while accelerating in 1st gear


Check the idler and tensioner pullys for your serpentine belt. I suspect the whining noise heard earlier was due to the fact one was getting a bit stiff or rough turning. When you gave it that extra fuel, the sudden load may have finished it off. Sometimes they lock up, and sometimes they fall apart. Check those items first.

Valves need adjusting and/or oil in the engine

With such limited information i can almost put my thumb on it being the valves - they are compressed using special tools, aka - leave it to the pros and save yourself a headache!

(In 1rst and 2nd the engine rpm is low, in 4th and 5th it is much higher making the knock more noticeable)
