'07 Volvo C70 B5254T3 with AW55-50 Fully Stock
I've had the car for a few months now, and my introduction into the Volvo car community has been great as an amateur to the brand. I plan on building the car so expect more posts, but for now I'll get to the point. I've taken the car on a trip already and even a 'spirited drive' on a touge, but the transmission has been rough with manual downshifting. I've been looking for some more information on it, but all that I've found is that the AW55 does not rev-match for you like the much newer Volvo 6-Speed automatic. To my knowledge the transmission fluid has not yet been changed at 128,000+ miles, which I'll be doing very soon. The transmission works just fine in automatic and I don't notice any kind of jerks or rough transitions. Back in manual mode, it also upshifts smoothly and with minimal delay.
So, what would be the reason for the harsh downshifting? I came up with a few explanations but I haven't driven the car in manual mode for a while with the fear of breaking something. The first thing that I've thought of was rev-matching. Since I assume the AW55 has a clutch like most torque converters, I took my guess that you would have to blip the throttle a little bit for the transmission to downshift smoothly while braking or cruising, just like a standard. My second thought was maybe the transmission fluid, since it hasn't been changed in ages and that's certainly the next job I'm doing. My third reason was, maybe the transmission itself is starting to go? Maybe the clutch is starting to finally wear out and I'm gonna be needing a manual swap.
If someone could tell me, I'd greatly appreciate it, as it would leave me one less thing to worry about!
