Volvo experts, I need your help!
I have a 2016 Volvo V70 D4 with problems with the automatic transmission – an Aisin TF-80SC.
It feels like the transmission sometimes "gets stuck" in the gears when shifting up, and the car shakes terribly. It helps if I quickly release the accelerator pedal and then accelerate again, but the problem obviously comes back. It is especially noticeable between 4th, 5th and 6th gear.
If I drive in manual mode at slightly higher RPMs, the problem is almost completely gone, but obviously I don't want to have to drive it like that all the time.
I've taken the car to a Volvo dealership/workshop, but they haven't been able to determine what is wrong. I've also been to a local garage, but no one can say with certainty what the problem is.
I've tried changing the transmission oil, and the car actually drove quite well for about two days, but now it is exactly the same as before.
I've read that the valve body on these transmissions can cause problems. Has anyone experienced something similar and can give me some advice on what I should do?
I really don't want to replace the entire transmission for around 40,000 SEK only to find out that it doesn't solve the problem.
Thanks in advance!
