    Default Transmission "clank" when engaging D or R / D engages in two stages -- 2004 xc70

    Hello all,

    Currently shopping, found a car today that I pretty much like, a 2004 with 240k kms... but.

    After a 10-minute test drive, the transmission made a loud clank when engaging D or R. Didn't notice it when cold.

    Also, D seemed to engage in two stages: a noticeable thud when first engaged, then a softer, second thud a split second later.

    I should note that the car has been parked since last December, aside from two recent and very short test drives (plates are expired). I was willing to take a chance today so went further.

    Thoughts, advice? Thanks.

    Any issues with the transmission on these cars, unless you are capable of doing the repair yourself, you should be advised to stay away,

    Transmission issues always show up when the car is warmed up because the fluid is hot, and therefore thin.

    Thin fluid simply doesn't move parts as well as thick fluid....

    "Clank" could be:

    1. Worn engine mounts allowing engine shift
    2. Worn solenoids allowing low operating pressure and delayed engagement.
    3. Tired fluid that's way past its life
    4. A worn out transmission

    I wouldn't buy this car unless it was both; really cheap, and you have the $$ for a transmission.

    It could just be fluid or a mount... but diagnosing on the internet is so very difficult...

    It MIGHT be...
    Low ATF fluid, dirty ATF fluid, Low fluid pressure due to worn Valvebody, early sign of trans failure.

    If it's making a metallic "clank" sound, yikes!

    Current owner should check ATF level, then replace fluid. Did he say if any work's been done on the trans?

    Thanks. I can likely get it for C$1200. So the cheap part is there. But not sure I want to change a trans.

    Thanks for all the input. I wrote a longer reply but apparently it was sent for moderator review, probably as I used a certain acronym for an expression the vendor uttered when he heard the noise....

    Gist of my reply:

    - no trans work done....
    - said Haldex has "been replaced" (showed me $3.3k bill, also incl. front axles), but I wonder if it was pump and seals (very cryptic bill)....
    - didnt think to check ATF as my current car has no dipstick, so I've got away from habit....
    - trans and driveline seemed flawless in normal driving....

    Thanks for everyone's input.

    Hard call for me as I liked the car. Have driven four so far, this was by far best in terms of driving feel and body condition, and that's including a 2006 with 100k less.

    A general note of advice you'll find in these pages: When buying a 14-year old Volvo, restrict your choices to cars that were proveably well-maintained,
    thru service records, CarFax records, stickers on engine, clean test drive, no abnormal noises, etc. A Volvo that has had maintenance deferred/neglected is a bad bet. If you're patient and
    know market prices, you'll find a good one. Also, look up how to test PCV suction. It's a red flag for the engine blowing an oil seal if there's no suction.

    The price you mentioned is just barely above what an inoperative Volvo is sold for parts or needing major reconditoning & repairs.
