Has anyone tried having their TCM software upgraded? I spoke with my local Volvo Dealer and they informed me that there is a upgrade for the TCM which "supposedly" addresses the rough shift points. I plan on having it done during my next service stop. The cost is $120.00 for the upgrade so I thought I'd check here first to see if anyone has tried that yet?

I too have the same shifting symptoms on my 00 s70...

yea i feel that to when you give it more gas then usualit does pull tug right after it changes, I thought it was play in the transmision but its not, i think it could be the torque at low rpm. One thing i dont like is that there is to much shifting, I have a 1999 S70 non turbo automatic, and it shifts a lot it doest give some gears a chance to run. ive driven other non turbos and its the same.

Hey there, I have a '99 S70 Automatic as well (non turbo), and I notice that if I'm really pushing it or even just driving it a little more aggressive than usual, the shifts between 1-2 and 3-4th are felt. The only up/down shifts that I don't feel are between 2-3rd. I too thought there was something wrong, but my Volvo Mechanic said that it's normal for these transmissions and my concern wasn't the first he's heard, though he did assure me that there isn't a problem. After driving a rental Taurus for a day, going back to my S70 did seem a little "harsh." - Not to worry, just think the shifts are "crisp." At least, that's what I keep telling myself.
