Hey Rawze,
I have changed out actuators and I was having power issues that got better. I’m still getting a jerk when it goes in gear. Do you think this it could be shift tower or something in the tune? It’s a white Volvo so I’m sure it has probably had some fleet parameters or something on it. Is there something in the ECM that could mess with your shift like that?

Without driving it myself, there would be no way tot ell what you exactly are referring to.

if you suspect an ecm program issue and it being a CM870 .. Get with running rough on here... Put the factory program in it temporarily to see if it clears up... then have it re-flashed back when you are sure it is not the program.
