    2004 cts makes clinking noise shifting from park to reverse or drive

    There are no other symptoms---yet! Anyone know what could be causing this? By the way the noise is under the shifter area under the car.
    Thanks!

    Re: 2004 cts makes clinking noise shifting from park to reverse or drive

    The problem is most likely related to a worn shifter linkage rod bushing or a worn bushing on the Shifter assembly. The shifter linkage rod (#13 on the diagram) has a bushing on the end where it connects to the transmission. The shifter assembly (#8 on the diagram and expensive) has a bushing on the bottom end where it connects to the linkage rod. When one or both of the bushings wear out, a very distinct metal-to-metal clanking sound will occur when the Shifter is engaged..

    These bushings are not available separately. You will have to replace the entire Shifter Linkage Rod, the Shifter Assembly, or both. The linkage rod is relatively inexpensive and fairly easy to replace.

    The diagram is not for sale I assume. PM one of the site vendors such as Chris (RippyPartsDept) and have him give you a quote. Forum members get discounted prices.

    Also can these "Shifter Linkage Rod, and Shifter Assembly" be replaced by "DIY". Does anyone have the GM part numbers

    Re: 2004 cts makes clinking noise shifting from park to reverse or drive

    I had my rear diff bushing, center bearing, and flex discs replaced and my car still clunks when changing into drive or reverse. It even still clunks when letting off the gas while driving.

    i've seen some threads around here that indicate the transmission mount if its sagging can also cause this issue. I ordered flex discs, trans mount, revshift insert , and rear diff bushing (and the shift linkage that always falls apart) I have the same clunk that seems to happen to all these cars. I'll let you know how I end up

    Re: 2004 cts makes clinking noise shifting from park to reverse or drive

    These are two entirely separate issues.

    Paul, the shift linkage in your car is whats making the noise. When I bought my car, it was doing the same thing. I took it to the dealership and paid the $145 or whatever it was to have it fixed. No more noise from that.

    The transmission mount/flex discs/differential bushing/cradle bushings problem is different. And is a lot more expensive to get rid of. Kudos to silver viper for doing it right and addressing everything at once. That is the only way to do it.

    I don't see Cadillacs as POS's at all. Very well made cars in my experience. Go get a VW to see a real POS.

    Re: 2004 cts makes clinking noise shifting from park to reverse or drive

    rickparker do you have the part number? Is it the same CTS part number as posted by Bluehaze above ( 3.6L Linkage part # 25757504) but the link above to a differen thread shows 25757505.

    Do you replace this linkage from under the car, or do you have to gain access through the center console from inside the car??

    Re: 2004 cts makes clinking noise shifting from park to reverse or drive

    I would recommend getting the proper part # based on your VIN from Chris @ RippyCadillac (he's in these forums) anyway you can replace the linkage from under the car. I did mine yesterday and I didn't have to undo the center console at all.

    So guys after spending all day under my car yesterday everything is done (except one teeny thing). Prep by sticking your creative steel bushing in the freezer, this should make it easier to drive in. My recommendation is to drop the exhaust because it will make everything much simpler and you only have to undo the four bolts at the exhaust up by the transmission (dont forget to unplug the O2 sensors) then undo the tunnel brace towards the back and you can drop the exhaust. That gives you all the room you need to replace the trans mount, and both flex discs (the rear one seems to bind up a bit for some reason) while you have all that down, undo the two rear bolts that support the diff (with a jack under the differential. You will need a 21mm wrench , preferably a ratcheting since those bolts are in a tight spot that a ratchet can't back all the way out) then unbolt the front differential bolt that will let the diff come down. My differential bushing was completely falling apart and the center section just fell out. then take a sawzall and cut a groove in the sleeve for the bushing. this will let you fold one side of the bushing sleeve in and the sleeve will just pop out (there is a video of this on youtube somewhere) then take the new bushing out of the freezer (find something the appropriate diameter to drive it in with) then just walk it in with a hammer. then put everything back together, reassemble the exhaust and take her for a test drive.

    After doing all this ( and then replacing my diff oil with Mobil 1 75W-90 (you need two quarts and from what I've seen you dont need the differential friction modifier for limited slip diffs based on the autozone reviews ) I have no more clunk! and since I replaced the linkage going to the shifter no more clinkity clink clink when shifting either! awww yeaaaah....! next weekend is my transmission service.

    oh yeah the one teeny thing? I wasn't able to get the revshift insert in the trans mount. I put a new trans mount in but the insert didn't seem like it was going in. I will get one of my more mechanically able buddies to do it and let you know how that goes.

    Sooo took the car out for a drive yesterday and I have a vibration at 25-30 mph, I wouldn't call it major, but noticeable. Its most noticeable when you let off the gas, which makes me suspect driveline angle. I will see if the revshift insert for the tranny mount makes a difference and let you all know here
