Transmission Fluid Change
Wheres a good place in Austin,tx to get this done?
Is it better to drop the pan and change the filter, or some places do a t-tec or just flush the system with this machine that is supposed to backflush the filter without needing to change it. Its a faster method and they dont drop the pan..Had this done on my truck but don't know which method is best for the vette.

Glad you asked the question. I am due for a transmission fluid change myself and would like to know if others have had the flush done on their corvette. I am going to go to the AMSOIL.

IMHO I can not image that a back flush does the the job well. It is just a quick and dirty way to get your money. I just replaced my A4 
with the help of Stangkiller. I want to make sure I protect my investment and change the fluid and filter in the future. There is also the inspection and clean out process of the magnet. Dropping the pan is a messy process, but worth it.

My advice
Sorry don't know anything about a place in Austin TX to get this done.
For the the money involved get the fluid and filter changed.
I would do it myself. The hardest part of the job is getting the car up in the air. The parts don't cost that much...filter with seal and gasket about 20 bucks...ATF fluid about five qts about 15 bucks. Thats it.
My 2 cents.

Sorry - another person that doesn't know squat about your area.
But I do know that if you have an automatic transmission it's best to go to a shop that has an ATF flushing machine - I am familiar with the T-Tech version. This machine will be attached inline with the trans cooler lines and proceed to flush the entire capacity of your transmission - and actually will push out all of the old fluid and replace with new. After the fluid flush the pan should be dropped and the filter changed. Depending on what kind of fluid you request this can cost from ~$129 up to ~$200.
If you have a man trans it's a simple drain and fill - 4qts.

I asked the expert flusher here and was told that they would only do a flush if necessary (meaning if the fluid was dirty). If it still looked okay, they would do a simple drain and replace. There's a hundred dollar difference between the two, so if they only want to replace, by all means, replace away!

Using flushing machines does not address the need for cleaning the sediment in the transmission pan, cleaning the magnet inside the transmission pan, or changing the transmission oil filter.
Though I'm not sure if all of those are applicable to the Vette, they do seem to make sense to me and I think I'd go with a drop of the pan if I had an auto.
FYI, for the couple of you above who said you were considering switching to AMSOIL, the AMSOIL ATF has recently been reformulated to comply with the newer Dexron VI specification (and is backwards compatible with Dexron III).

DJ, if you follow the link on Subdriver's post you will see the AMSOIL recommendations. It seems as simple as 1. buy the fluid and filter to have on hand, 2. loosen bolts on pan (loosen one side more than the other to drain fluid into a catch container), 3. Remove and replace filter, 4. clean pan and magnet, 5. replace pan and refill with proper fluid. Obviously we do not have a filler tube and I did not look at the transmission case to see if there is a filler hole. I also have an A4.

The link in my post above is to my dealer website. I know that is a good link. On the page of my dealer website for the AMSOIL ATF, I have a link direct to AMSOIL's website to a pdf file on automatic transmission filter change procedures. I just checked that link and it works for me. But, it does link to a pdf file. Do you have Adobe Acrobat Reader installed?
They used to be very very similar, but with the recent reformulation of the ATF to meet the new Dexron VI specification, the ATF now has a slightly lower viscosity which may further improve shift feel, particulary when cold. And the ATF performs slightly better in the 4-ball wear test than the ATD. I'd go with the new ATF.
