Hello,
I bought a 2007 xc90 3.2l v6 with 120,000 miles on it. When I test drove it it seemed fine so I bought it, when I decided to do maintenance on it I stumbled across a couple of issues. When the car is in drive but I hold down the break the car vibrates unbearably (same while in in reverse). The second problem I encountered after changing the transmission fluid is the car shifts late when pressing the accelerator at around 3k-4k rpm and then it hard shifts with no clunk. the original transmission fluid was black in color and low at around 2 liters.

I thought it was the engine mounts in the beginning, but they seemed fine except for the upper and lower torque mounts that needed to be replaced. After replacing them it helped with the vibration and the clunking however it is still there. I replaced the transmission fluid and it has seemed to bring up the second problem. Has anyone encountered these problems before?
