WELL THE XC IS AWD so will be worse on fuel economy due to drivetrain losses

2004 XC gearbox: reluctant shift
THANK YOU very much, Georgandkira, for your encouragement in that direction. Now I just need to find out which gearbox I have which should not be too hard. Cheers!

Thanks, Barrybritcher. I'm looking forward to a whole lot more miles per gallon than with the Landcruiser D4D! The XC70 will do the reduced towing duties that I now need very well I think. Cheers!

In normal use with a healthy gearbox, should the gearchanges at light throttle and low speeds be completely imperceptible without looking at the rev counter?
My gearbox gives little noticeable "kicks" when changing in lower gears during normal driving not sure if thats normal or not. I know my gearbox can get a bit fussy when the fluid is very hot , normally around 3-2 2-3 changes hesitating then banging into gear, but under my usage, its quite rare. Ive done the first of several sump-dumps which has improved things slightly with several more to go in the future.. I didnt reset the fluid counter or anything in vida. |

To Gee19: How dirty was the fluid? I assume fairly dirty as you sound accepting of "more to go in the future".
Your transmission will thank you....seems it already has. I suggest adding LubeGard (red bottle) at the recommended dose (1 oz. per system quart) once the fluid is acceptably clean. I do not believe in "mechanics in a can" however, the LubeGard line is used by pros. 10 years ago a TCM download improved the shifting in my 2002 V70. After that I read about LubeGard on the oil fora website and tried it. The additional improvement was amazing. DISCLAIMER: I have no £-$-€ interest in what you buy/do. |

Slipping Lock-Up Issue (AW55-50/V50 2.4i)
Good day to you all. I am having an issue with the AW55-50 geartronic gearbox fitted into my '04 2.4i V50 (> 130k miles) and after reading through the majority of the past 40 pages of posts in this thread I am hoping that one of you may know of a solution to my problem.
FYI: I have already had a thread on this issue in the S40/V50 forum HERE. I acquired the car in March '19 and in November '19 I noticed an issue with it where the RPM was fluctuating at low revs. I did some research and the symptoms I am seeing match the conditions under 'Volvo Shift Modes: Locking Slip-up' but they are greatly exaggerated with the RPM fluctuation sometimes being around 300-400RPM. The occurrence is varied, it probably occurs 75% of the the times the conditions are met but when it starts to happen it is almost continual. When it occurs you can feel a change in performance, going from smooth to sluggish as the RPM fluctuates. The Sonnax site describes the feature as follows: https://www.sonnax.com/tech_resource...urers-part-one Slipping Lock-up – Slipping lock-up mode allows for a smoother lock-up engagement while reducing vibration and noise. The computer maintains a 50 to 200 RPM torque converter clutch slip in this mode. The following conditions must be met for this mode to activate: Gear shifter must be in the D, 4, or 3 position. Transmission must be in 3rd, 4th, or 5th gear. The transmission input speed must be 1100 RPM or higher and the throttle opening must be 35% or less. Engine coolant must reach a certain temperature. Transmission oil temperature must be at least 40°C (104°F), but not to exceed 120°C (248°F). When I purchased the car, nearly two years ago it had a full main dealer service history but I could find no record of an ATF change so in April this year I took it to a local garage for a ATF change. I understand this was simply a change, not a flush. This did not resolve the issue although it did appear better for a little while. When the conditions of the slipping lock-up feature are not met, which is generally when it goes above 2k RPM, the gearbox appears to be otherwise smooth and the engine gives strong performance with no indication of slipping from the gearbox. On a cold morning just after starting you can feel the first few changes but as soon as the temperature gauge starts to rise this goes away. I am wondering if it simply needs a full ATF flush and a software update?

Volvo S60 d5 automatic problem
I own a Volvo s60 2002 year, D5 motor automatic. Ever since I bought it last year I have had a problem. When I drive it in the city or on the terrain where it sometimes asks for a frequent gear change, the gearbox starts to jerk on 1-2 and 2-3 gears, somehow enters that bad algorithm and remembers it and continues to change it like that, until I turn off the car on 10-15 min, after that it works without problems. It also stops twitching when I press W (winter) mode on the gearbox, but when I return to D it twitches again until it sits off for 10-15 minutes. So in W mode it changes without any problems. I've got answer from someone: In the W mode the gearbox is skipping the 1st and 2nd gears so it stays in 3rd or higher - it is not recommended to leave in W as it may cause quick transmission wear. The fact it works fine after restarting may look like something electrical. Thanks in advance
