Unless you're sure they are gonna do the proper flush I wouldn't suggest.
My tranny was initially slipping between 1st and 2nd and a partial flush was done,by that time tranny had 183.000 kms on it,no idea how it was serviced.
In about 3 months it started to shudder,got sick of it and had it rebuilt,no luck,shudder was still present after rebuilt + the Whining during the cold starts(aftermarket filter was causing that).So I started to research for info about shudder causes etc. Finally I checked the bill and found out that that the filter was a cheap piece of crap and not ZF as I was told(funny,no?) and tranny was filled with Dexron IV fluid.I bought the fluid and requested the flush,they were pissed and skeptical about any effect,but flushed trice,making it almost a full Dexron stuff flushed away.I drove for two days now and felt some kind of smooth slipping at the point I used to get a jerky Shud-d-d-d-er.
About a filter,filter was replaced and fitted a brand new Filtran branded one.No more Whining at all.
So here's the conclusion:
Unless you can be sure about what they are doing,force them to flush,but I would keep an eye on the Proper fluid kind which is LifeGuardFluid5 or Esso/Exxon LT 71141(in my case it was Mobil Super MultiVehicle ATF which is LT 71141 among other specs) and get the filter replaced as many say that the new fluid will disturb the old crap deposits in the valve body etc.
So new filter is the MUST.I would get it replaced every flush( you would need at least 2,if they are flushing without the Torque Converter,drain plug flush I would say.
Good luck.
