Hi there! New here.

I have a Volvo V70 T5 automatic -98..

And it started to behave weird with flashing arrow up light "stuck in winter mode/3rd gear" and gave me some codes: P1618 and P0605, So I tought that getting a new TCM would help.
But with the "new" TCM I get codes: P1618 and P0602 so no more P0605 but still the same problem..

What do I do to fix this? Did I get the "wrong" TCM? I can get another one that all the numbers on the TCM itself correspond to the ones on my old one.. Will that do it?

 

It was the wrong tcm. I bought the one that had the corresponding numbers

Just to helt others out, never jumpstart the car.. Cus it will fry your tcm
