How hard is this to do on a 1994 850 Turbo? The dealership said it's basically just drain and fill. I'd like to do it myself and save $100.

Can you guys give me the low down on this...

Thanks

 

Very easy. The only thing is that the clips like to break.

This sit he method I used.

Depends on how you do it. All I do with mine is jack the car up and put the front on jackstands with the front wheels off the ground, drain it, put the drain plug in finger tight, refill it, start the car and run it through the gears for a couple minutes in each gear, drain it again, refill and do this about three times. On the last time tighten the drain plug and put a new crush washer on it. You only get about 1/3 of the fluid out with a drain. Some people prefer to actually flush the system, but if it has more than 100k miles on it that can lead to more problems than it's worth. Basically you just want the fluid coming out to look almost as good as what you are putting in. It's as easy as changing the oil, maybe even easier cause you don't have a filter to mess with. Make sure you do not over fill.

Oh yeah, make sure you use Dexron III in your 850.

Couldn't have said THAT any better!! We have an 01 XC70 as well as the 850, and the XC uses a special type of fluid that is more of a pain than it is worth.

As for the entire drain/fill procedure, follow the above advice and you will not have an issue.

Good luck

 

+1 for sticking to Dexron-III/Mercon. I would also avoid synthetic fluid, as there does not seem much benefit in synthetic tranny fluid and I remember one person's report that he used Castrol's Synthetic fluid that meets all kinds of transmissions, domestic & import, and his tranny failed to operate normally. Generic Dexron-III/Mercon is all you need. Tranny fluids are not compatible.

Just an update.
Dexron III is no longer available. The proper substitute is Dex/Merc. That is what replaced both Dex II and Dex III.

I was fishing for the drain plug size. 24mm or a good 15/16" six point works too.

l used synthetic for more than two years and never had a problem.my tranny even shifts better with synthetic. Synthetic flows better and in an extreme hot weather it helps run the tranny a lol bit cooler. The person prob had a problem because he had the wrong fluid type.
