Unable to remove knob from shifter lever
 
Re: UK Reg 2002 Jeep Grand Cherokee WG 2.7 CRD Limited Auto

Hi All,

I'm trying to remove the knobs from the shifter assembly so that I can remove and check the electronic module that sits on top of the unit.

The one on the Hi/Lo transfer lever pulled off O.K. but I'm having serious trpuble with the one on the gear change lever. I've pulled like hell, used a lever set up (see the recent thread from "Kennytheone") and there is no way I can get it to budge.

Is there a trick to this? Am I missing something here?

I'm prepared to listen to any half-way sensible or even, ridiculous, suggestions. I really am getting desperate.

You should be able to inspect what you need to without removing the knobs (you'll have to remove the floor console regardless: Jeep Grand Cherokee WJ - Floor consoles )

Hi Milous,

thanks for replying, but I think the picture you attached is of a slightly different assembly to mine, attachment refers.

The unit I am working on is out of the vehicle. I need to able to get the PCB on the bench to check track and solder joint integrity, and component functions, but can't get the PCB past the knob on the gear lever.

That wretched knob must come off somehow, logic says the knobs are the last thing to be fitted when the unit is assembled. Any ideas?

I've been keeping track of your progress, as I am curious as what causes the lights to fail. My shift console selector lights don't come on unless I've been driving for a hour or better. Maybe try a stronger penetrant like deep creep or PB Blaster.

The shift lever assy for diesel jeeps (as in the case of Tony) is from a different design then the one for the gasoline jeeps. The diesel version is a microprosessor controlled unit, where the shifter lights are controlled by the microprosessor.
On the gasoline versions the shift lever assy is far more simple and completely mechanical. The integral lighting is from the electroluminescent type with a separate power supply, which works on 120 V (so be carefull for the shock hazard). There is a thread about this lighting system, i will see if i can find it again.

I will keep an eye out for said thread. Thanks.

Just found it, but i see that you already responded to this same thread: http://www.jeepgarage.org/f203/shift...cts-45802.html
Sofar no real solutions. There was a French guy on here who told that the power supply can be changed for a comercially available one, but he didnīt say where you can find it. Also the manual is stating that the power supply is 120V, while on attached thread he talks about 450V 120 Hz. I only wonder if intermittent working lights will be due to the power supply, or due to some breakage on the lighting plate. A LED conversion would be interresting, but donīt know if its feasable.

I've done this a couple times and yes, the knobs really do come off, despite what many people will tell you. There is an internal snap ring that holds this knob onto the shift lever column. Plus the fact that I'm sure yours hasn't been removed ever, this is no easy task. Keep in mind that the snap ring is holding this and the knob is tight on the column shaft. You will have to push down, pull up and wiggle from side to side repeatedly over an extended period of time, rather violently, to get the snap ring to allow the knob to come off. I was using upward forces of maybe 75 to 100 lb/ft of force at times and working on this for about an hour. Also, take a look at the shift knob as there is an integral switch that has wiring which you do not want to damage when you pop the knob off. If you can't control the explosive force of pulling when the knob comes off, you'll destroy the wiring attachment and then you will basically have to buy a whole new shift assembly at a cost of some $600 to $1,000. You can find the electro-luminescent displays at junk yards. Of course, to get one, you will have to pull off the shift knob in the junkyard jeep as well. Chrysler does not sell parts for this shift assembly, only the whole assembly as you probably already know.

You can do LED conversion, it's easy to do and can be connect to the old wiring. The lights will still dim with the dimmer, but they'll be a lil bright still. That's easily fixed with a small touchscreen dimmer (has 5 or 6 settings).
