Just ordered up 2 gallons of it. Going to give it a shot in my 10R80....but not all at once. Next drain and fill will probably be 50/50 Valvoline Restore and Protect and Mercon ULV and I'll be keeping close tabs on the shifting.
Did you flush it or do a drain and fill? What percent of fluid in the transmission would you say is Valvoline Restore and Protect?Small update on the XC90...
I don't see how fluid can affect this but something has and the fluid is the only thing that has changed. To save fuel and reduce parasitic losses, the transmission is designed to drop into neutral while stopped. For the longest time, this vehicle would drop into neutral -just before- I came to a complete stop. Because of this sudden change in torque/engine braking, smoothly coming to a stop was difficult. Now, it stays in gear till I have come to a complete stop. I noticed it this weekend. It's definitely a welcome change because it feels much smoother coming to a complete stop. I don't have to try so hard to suddenly change brake pressure to maintain smoothness.
I did a drain and fill. I've actually done three. The first was with 4 quarts of Aisin ATF-0WS. The second was Valvoline Extended Protection. And the most recent was Valvoline Restore and Protect ATF. I think the entire transmission holds 12 quarts and doing drain and fills is obviously nowhere near the same as doing a full flush. Judging by the color of the fluid, I need to do three more for it to be like new -red-. It's still brown, just a light brown. To answer your original question; at best, 25%.D

And you only noticed the shifting improvement after the Valvoline Restore and Protect was added? Or did the new fluid from the others make a difference?I did a drain and fill.

Yep. I noticed two things actually; first I noticed a smoother downshift a week after the Valvoline Restore and Protect went in. It has been a few weeks now and I just noticed the improved neutral response. Before that, there was zero difference. I was just changing the fluid because it had never been done in the vehicles 100K mile life.And you only noticed the shifting improvement after the Valvoline Restore and Protect was added?

Did my second drain and fill. By my estimate I have about 35% AC Delco (15% from original fill), 50% Valvoline Dexron VI, 11% Valvoline Restore and Protect, 5.5% Extended protection. I was nervous about adding too much non-Dexron VI approved fluid. Hopefully the 11% will do something. Will probably do more Valvoline Restore and Protect in a couple years if the reviews continue to hold up well.

The transmission is shifted into neutral when stopped. Since I've owned this vehicle, it has always gone into neutral just before I stopped. Which made smooth braking, especially just before coming to a stop, a little jerky. Now it shifts into neutral just after I've stopped. Which makes the vehicle feel a lot smoother because I don't have to try to modulate brake pressure to smooth the braking performance.What do you mean by neutral response?
Interesting, never had an auto that moves itself into “N” …The transmission is shifted into neutral when stopped. Since I've owned this vehicle, it has always gone into neutral just before I stopped.

There are a lot of vehicles that do it. It's supposed to be unnoticeable. Volvo was doing it back in 2001 but the 5 speed AW gearboxes were burning up the fluid and torque converters so they released a software patch that stopped the "neutral control" system from functioning and prevented issues.Interesting, never had an auto that moves itself into “N” …
This is interesting. Thanks for updating us. This would seem to correlate with some deposits being removed. I'd expect the benefits of fresh ATF to be immediately apparent, but benefits showing up in a delayed fashion seems to me at least that some cleaning happened.It has been a few weeks now and I just noticed the improved neutral response.
You'll be fine changing the filter and adding the 5 or 6 qts. You're dumping old Valvoline for 100% compatible new Valvoline.I was working on my 2007.5 Silverado and decided to drain and fill my rear diff and I didn't pay attention to the previous owners maintenance records and I thought he had serviced the transmission at 72k miles but it was at 52k miles. I thought I might as well do the transmission. Now I'm at 128k miles and not sure if I should use R&P and just use the Valvoline Dexron VI/Mercon LV Full synthetic that he used. I don't want to damage the transmission but I do want to service it. I planned to just change the filter and add 5-6 quarts. I know it isn't good to flush it but not sure if I was to keep pumping several quarts through it until I have 100% R&P but not sure what would happen if I just add 5-6 quarts of R&P.
How many quarts would I need to run through it to get to 100% R&P?
I think this is a myth. If a transmission fails after changing the fluid, it was already dead to begin with.I don't want to damage the transmission but I do want to service it. I planned to just change the filter and add 5-6 quarts. I know it isn't good to flush it
Great data point.Any modern (last 20-25 years?) transmission I’ve serviced, generally all with high miles (150k+) have only had excellent results from fresh fluid. That would be Ford, Honda, Chrysler, Hyundai, GM, and Subaru in my family.
