Tranny and brake fluid flush?

Recommended Posts

Edit: I orginially posted about the trany AND brake fluid flush, but axing the tansmission flush. After doing some searching online I checked my fluid and it smells new, is still pink and between the fill lines.

 

My 2008 Edge SEL has ~92,000 miles on it. We bought it used at around 60-65,000 miles with no records of previous maintanence. Since I got it it's been through mostly city miles. Would you recommend a brake fluid flush/replace? The car always felt a little spongey when breaking but that seems to be a thing with all Edges this year.

 

Bonus: I need new tires!! I'll be living in Buffalo, NY this winter, so that means lots of snow. I did the penny test the other day and all tires are pretty worn. I'd like to get a good pair of all seasons that handle reasonably well in the snow. I just graduated and will be moving out next weekend so I don't necessarily have money to spend on 2 sets of tires. Any recommendations? I have FWD if that means anything.

 

Thanks! :hat_tip:

I would recommend a transmission fluid complete change. I have posted several video's on this subject. Also you are way over due a brake fluid replacement. Last but not least a full Mercon V power steering fluid change yes it will use the same fluid as the transmission. Made a video on how to to all this so it is simple. You can do all this for under 250 dollars easily and that is if you have a garage do the transmission flush.

I'll have to wait 'til I move this weekend, but it's on my list! It's funny you mentioned power steering, because in the fall my entire power steering system had to be replaced :drop:

Mac, what do you think is a good interval for a brake fluid change. I have somewhere around 93k, been kicking it around getting a brake job. (Hate my brakes). You recommend a fluid change when I have this done? (It's not listed in the maintenance manual).

Thanks, I'll bet it has never been done. I'll have them do a full flush when I have new pads put on.

Any way of telling how much moisture the fluid has absorbed? There such a thing as brake fluid tester?

 

Color. The darker the fluid the more water it has absorbed (I think). It starts out clear.

When I flush the brake fluid, I suck out the brake reservoir as empty as I can get it, then fill with new fluid. Then I bleed the brakes from the furthest to the closest using the one man type bottle -RR, LR, RF, LF in this order. After each brake is bled, I refill the brake reservoir so I don't bleed air into the system. It takes about a liter of fluid - of course depending on how much you bleed at brake cylinder.

 

WRT transmission, I read in a Ford service manual to "drain, refill and drive a bit", and repeat 2 more times about every 25,000 miles. It is not a complete flush but IMO is safer than doing a true flush which could dislodge crap in the transmissions - lots of opinions on a flush versus a drain and fill. The only thing I'd like to do is change the filter, but removing the vertical pan to do this seems to involve disconnecting some electrical connectors and not worth it to me as a DIY'er.

Bad. It should be clear. Won't hurt to replace it.

Just called local ford dealership, a flush is $99. Having it done tomorrow :)

 

Edit: checked power steering and transmission fluids and they're all good & at max level. Stopping at Autozone today for a new air filter that I'll throw in my self. My dad helped me clean off the gunk on my battery and added water

Soooo for my break fluid: good, bad? Leave it, replace it, or flush it?

After I read akirby's post, I looked it up. Good fluid is clear or translucent. Rust colored means that it's absorbed water and should be flushed. Blackish color means brake problems and everything needs to be examined.

Here's a before and after from my break flush . The breaks feel a little less spongey & seems to have more confidence :love_shower:

 

Last question I promise... I think there's air in my power steering system. It's all brand new (replaced early Fall) but it's pretty tight. Would a power steering flush take care of this? I have to get new tires soon and would get this done at the same time.

Brake fluid looks much better! You might want to periodically watch it to see if any debris comes out, and replace a bit at a time instead of flushing. Take what's accessible in the reservoir (no more than say till 1/2 way down the neck) and replace.

 

For the power steering fluid, have you tried getting the air out by a] verifying the fluid is indeed filled correctly to the FULL line, b] taking the reservoir cap off, and c] turning the steering wheel lock to lock 10x or so (do not hold at lock position) while the engine is running?
