99 v70 transmission options

[huzzsaba]

I know that the transmissions are the same except that some have the just winter mode and others have 3 modes
(eco/sport/winter).

My 99 V70 t5 has the winter option only, while my brother's 98 s70 and my other brother's 95 850 (both non turbo) have the 3 mode transmission.

On my car, the shifts are rather quick. One time my brother came over and he wanted to feel what kind of power the t5 delivers. Even he was surprised at how quickly it shifts.

I don't think I have ever WOT the car since I am afraid of messing something up, but is this something that the transmission learns? Or is it designed to shift that way.

I use to own 2 855 turbos back in the days and loved the feel of the sport shift.

Oh and BTW, my brothers only drive volvos because I rave about them so much. I am the only genuine enthusiast lol.

Thanks

The sport/economy feature is solely in the transmission computer and selected between the two by the switch. Winter is selecting 3rd gear for initial gear for moving off.
The 99 and later use the same exact gearbox as the 96-98 with the E/S/W selector but with two sensors changed from analog to digital type sensors to suit the new processor in trans computer. This change is coincidental and has nothing to do with the drop of the E/S functions. The newer functionality assumes E mode for throttle application rate that is less severe and when throttle request is less than roughly 30%. If you drive more aggressively the change rate and amount of throttle is greater and the S mode functionality is now assumed. E and S are just different schedules of road speed vs throttle and load that yield an upshift. E mode is shifts at lower road speed for the same throttle compared to S mode, in effect E keeps revs lower by shifting sooner. On cars with E/S/W selector, E position reverts to S mode at something around 70% throttle.
"learning" of transmissions is far simpler than many think. The transmission only learns to not let shift time go too long which is more slip and more wear. If a shift takes over the target time then the TCM (trans control module) will change the fluid pressure higher to shorten shift time. The TCM does not "learn" how you drive. If you drive easy for a LONG time then the slip has not occurred and then driving more aggressively may make it mushy at first followed by firmer shifts after it "learns".
The delayed shifts at wide open throttle only occur if you fully hard depress the pedal. This is another shift program that holds shifts to maximum engine speed and bumps fluid pressure up for shifts an additional percentage to assure no slip at full power. The only transmissions that do "learn" your driving do it to a very limited extent and for specific situations. If you drive on a road where you are climbing the side of a mountain and there are switchbacks every 1/4 mile then the 3rd or 4th time the throttle is lifted for a turn and trans upshifts and then you get into throttle and it has to downshift a gear or two, TCM will decide to hold the lower gear on lift throttle on that repeating pattern.
