I have been told that after my 3000 mile ARX cleaning I should bring my car to a T-Tech location for the ATF change. And they do NOT need to replace the filter?
I have a 1995 Camry Wagon which I Auto-RX'd and then T-Teched at my local Toyota dealer and they did not change any filter. I was told that there supposedly is no filter in there to change. Yet when I check at some on line auto parts place they say there is one. Now if a Toyota dealer said there wasn't one to change and since they usually want to make a buck if there was a filter to change they probably would of put one in there. That was about 1.5 years ago and I haven't had any problems with the tranny.
If you do the T-Tec procedure, they never even drop your transmission pan. They hook up cooler lines to a machine which allows new fluid to be introduced while old fluid is pumped out.
Personally, having done both in the past, I prefer dropping the pan. It gives me a chance to inspect for excessive clutch material, clean the magnet, and replace the filter (in my case, I have one). It's messier and takes more time, but I find it effective when done properly.

That corolla has a metal mesh for a "filter" which is replaceable if you want to do it, but there is no pressing need to do so. On my '01 prizm (same engine/trans as the '99 corolla) I left the filter and pan alone and did an arx treatment followed by a home-done flush.
To do the home-flush you disconnect the hose heading to the transmission line inlet and connect an extension to it, which then goes into an empty 5 gallon container which is on the ground. Then put about 10 quarts of fresh ATF into another 5 gallon container, this one which is placed onto a board which lays on top of the engine, and then start a siphon line which sucks the fluid from that container and runs it down to the transmission inlet. Put the car in neutral and run it for about 20 seconds during which time the empty container starts to fill up with old fluid while gravity is siphoning out the new fluid from its container and puts it into the transmission. The transmission pump will spurt out fluid more quickly than gravity will refill the transmission, so the process goes like this: 20 seconds with engine on, 3 minutes with engine off, etc. After 25 minutes you will have flushed your fluid completely for just the cost of the fluid.
T-Tec cleans the filter in your transmission if you have one by circulating the fluid under safe pressure right through the filter (cleaning it to) i don't care how people clean there transmissions however on automatic units if you don't clean the torque converter you wasted your time along with Auto-Rx and transmission fluid.
...however on automatic units if you don't clean the torque converter you wasted your time along with Auto-Rx and transmission fluid.
I disagree to an extent. The fluid you are replenishing will mix with the fluid in the torque converter. Alot of transmissions now do not have a way to drain the TC. I do, however I dropped my valve body on my last change in order to drill the separator plate and remove some springs. In all, I had to replenish 10 of the 15 quarts it holds. The other 5 will mix with the new fluid. So long as the old fluid is not dirty, I don't see a huge problem with that. Mine was still bright red w/ 30k on it and 6oz. of Auto-Rx added a thousand miles before I dropped the pan and VB.
In other words, what I'm saying is if the fluid is not dark and dirty, doing a "Service change" is okay - drop the pan, replace filter and clean magnet, and refill with appropriate amount of ATF. Never use "compatible" or "universal" brands of ATF, with the exception of Amsoil's.
And T-Tec does not clean the filter. If it did - the filter failed at doing it's job. The T-Tec uses the transmission pump to change the fluid, in the same direction as normal operation. If debris got through the filter in the T-Tec service, then it did exactly what it was not supposed to do. I always replace my filter. Cheap insurance.

I think you're misreading what Frank is saying. When a trans shop does a rebuild they often insist in a NEW converter due to their lack of ability to clean debris from the converter. Auto-Rx assures that any embedded or attached material that's not supposed to be there is suspended and removed.
Doing your own cooler line exchange works. It's real easy. Just unhook one of the lines (have a spare piece of hose in case you choose the wrong one) and run the engine until the flow is visibly reduced. Add fluid. Repeat until you've processed XX number of quarts (varies with application) and then hook up the line and top off the level
