Apparently, all current 8-speed S/V/XC models utilise the same gearbox, Aisin AW F8FXX (called TG-81SC by Volvo) so they are all shift-by-wire. It must be just a market decision to limit Orrefors to T8 in your market as my S60 B5 has it.

All three XC90's we have owned (2017, former 2020, and current 2021) have a mechanical shifter (T6's). I believe all T8's (recharge) have the electronic shifter. And I believe the XC40's have them too.

Same transmission, yes. But the T8's are front wheel drive from the same transmission only. The ERAD (electric rear axle drive) turns the rear wheels on the T8's. So entirely different shifter. That's at least my experience in the US market.

I struggle to find mechanical shifters from the whole Volvo line-up for my market. The only mechanical shifter I am able to find is in XC40 T2 with a manual gearbox, each and every other model seems to have an electronic shifter. But then again, I'm looking at the current offering and can't say what the situation was a year ago or even earlier. Things may (and likely) have changed.

I still don't think the power unit (T8, B5 etc) makes any difference. Since TG-81SC is electronically controlled the shifter construction is independent from the gearbox as long as it sends correct signals to the box, which means the power unit per se does not dictate the shifter construct. It is purely a branding issue.

So what I'm saying is that while the power unit or the gearbox do not constrain retrofitting an electronic shifter, the other construction (housing, wiring, control units, etc) around the shifter makes it very likely impossible.

I've been doing research on the XC90 for the last few hours for my parents and the T8 has the hybrid battery in the middle console, pretty sure that's why the shifter is shift-by-wire cause there's probably no space for linkages to the gearbox

In US, T5 T6 shifter is mechanical. You can easily tell by the force needed to push the shift stick. In other regions this should be the same. T8 is shift-by-wire electronic shift of course. XC40 is shift-by-wire, even with same Aisin 8AT transmission.

Whether XC90 B5/B6 now gets shift-by-wire, it is a question their owners could answer. Not many B5/B6 have been delivered so the info here is rare.

So there is mechanical linkage running from the shifter all the way to the trans to engage park and select gears?

I am not technician but I believe so. The final activation of gears maybe by some solenoid and fluid valves but the shifter uses mechanical force to trigger the shifting.

While T8s and T4/5/6 FWDs have some commonality (all ‘generation 2’ engines with the same variant of gearboxes), the gearbox used in the T8s is a different part, least of which due to the servo-actuated gear linkage.

All 48V (generation 3 engines) and twin engine Volvos produced today are shift-by-wire. Not exactly sure on the reasoning for the 48V cars, whether it was to distinguish them as being electrified, or for some overall powertrain benefit.

The original reason for the shifter in T8s is due to space restrictions. The base of the mechanical shifter extends about 6-8” below the main surface of the center console. In fact if you remove the side panels on a B5 and a T5 for example you’d see a substantial void that previously accommodated the shifting mechanism
