Re: Transmission Fluid - Flush or change
[quote author=Flyersguy172 link=topic=128903.msg2758274#msg2758274 date=1227199871]
I took my 2006 Mazda3 with 31,000 miles to the dealership for an oilchange and they recommended a transmission fluid flush. Should I really be looking at a full transmission fluid flush, or would it be ok to just change the transmission fluid?
i've heard some horror stories when it comes to flushing components like this but then again I'm not very knowledgable with cars so I thought this would be the place to ask!
go ahead and get the flush done. you have nothing to worry about. like John said, they use the cars pressure to push fluid through the cooler lines. most places nowadays, however, will send a tube through the actual transmission dipstick tube, and run a machine that will take small amounts of old fluid out, and put new fluid back in. thats the machine we use at my shop anyways, and I'm pretty sure most other places do this too, because there is less chance of error and liability (since your not tapping anything)
as far as fluid colors, don't go by that. i always say change it out whenever your manufacturer recommends, or earlier (like Daniel), but not after it gets discolored and funky smelling.
wild guess says you drive an automatic, but just in case, a manual transmission is a gearbox that needs to be drained and filled. a flush cannot be performed, and isn't necessary.
