I have an S80 V8 with that transmission. I've had the occasional weirdness with the shifts, but nothing like my dad's previous 06 S60R had. I wonder if part of it has to do with how the transmissions shifts between the two cars. The S80 is very lazy.

Doesn't the P* use the same tranny? And they make 500nm... I doubt Volvo/AW would spend the R&D to beef up a transmission they're phasing out.

I'm sure it's the same transmission, but with different internals.

I've got 06H for my S80 V8. I've got slippage that happens while it's cruising in gear at low engine load.

I'm figuring it's the valve body. A flush got me 8 months of perfectly fine functioning transmission, though.

Does anyone have any experience with having a VB done in a P3?

I'm guessing I'll have a hard time finding people with experience on this...

Just got my VIDA back up and working. Reading about replacing the VB.

The S80 V8 explaination is pretty basic. It's essentially "Remove airbox, drain transmission, disconnect cooler lines, remove panel, disconnect electrical connections paying attention to which one goes where, remove VB, install new VB, connect electrical lines, use sealer to reinstall cover, connect cooler lines, fill transmission"

No mention of the subframe. So just to make sure, I read up on it for the P2 chassis and it explicitly mentions dropping the subframe a bit. But the instructions are quite a bit more detailed on the P2. Less so on the P3.

The S80 TF80SC has a dedicated transmission cooler. So it could just route differently.

^^ And that's why I'm not too enthused about opening mine up to replace the VB. I'd hate to drop $1200, and however many hours it takes, only to have it still act up afterwards.

 

[D-man9000]

Wow, kinda harsh there.

I've got symptoms that could easily be tied to the torque converter(which is different in the V8) and not the valve body.

So yeah, I don't feel enthused about replacing the VB and hoping for the best, and discovering that I still have problems.

 

[D-man9000]

I'm at like 110k

The shifts are rough-ish, from 1-2 and 2-3. But the real weirdness is slippage after gear changes. I can be cruising in 6th at a low engine speed, and I can watch the rpms climb and fall. Maybe it's all just the VB, but that sounds like it could be the TC to me.

I know that on the V8s, the TC is locked up nearly 100% for fuel economy. So it's different than the other engine options.

 

[D-man9000]

I'll have to see if my DICE unit is still working

 

[D-man9000]

Yeah, mine does the same. It's not too bad. Except that sometimes, it shudders going up hill.

And after each gear change, as the car begins moving, it will slip once. Every time.

Something's definitely messed up. Totally driveable, I just don't know for how long.

I probably will wind up swapping the VB when it finally warms up again.

'08 V8

CarFax shows 8/31/07 for build date.

Transmission #07D

Torque converter symptoms - purchased it yesterday with 96k on it. It has a shudder at slower speeds (in gear, not during changes) when driving up a hill, and you can see the tach fluctuating by about 50-100 RPMs at steady throttle input.

I get that too.

 

[D-man9000]

I did the same thing. The crappy shifting came back in 10 months.

But I'm wondering if I've also got a torque controller issue.

 

[D-man9000]

Mine has only ever done one neutral moment when shifting, in the years I've owned it. Everything else is shuddering on gear changes, and at low speeds up hills in say, third gear.

 

[D-man9000]

Did you swap the VB? Was it the torque converter?

Oh jeeze, haven't been paying attention here.

It was the torque converter. Ditched the car. I mean, the valve body was probably also trash. But my problems were most likely the TC when I ditched it.
