01 Celica Trans fluid replace

[ohiotoyota4]

My daughter has an 01 GT, the manual says the Trans fluid never needs replaced under normal driving conditions.

Is it wise to never replace it or should I have it done since it is reaching 100K miles?

I can't answer your question, but I'd LOVE to know the answer to this myself. I admit I'm bad and I've never had my transmission flushed and now have 140K miles on my 2000 Celica...and now am being told NOT to flush it....

With that mileage better to leave it alone. You'll be asking for problem if you flush the tranny.

Eric, thanks for your reply....that's what I had been told by a few others...of course AAA Car Care insists that I flush it. I was told that it would be a good thing to have someone (mechanic) drain the tran fluid out and fill it back up, then drive for about 5K miles and drain again and add more....any ideas/thoughts/advice???

My dad was my mechanic but he passed away 3 yrs ago and I've yet to find someone that I trust with my car

Mr friend that is a mechanic mentioned exactly what is stated below.

"If your vehicle has high mileage (> 80,000 miles) and the transmission has not been maintained, I would not recommend replacing the fluid and filter. The fluid that has been in the transmission all this time has become dirty and gritty. This gritty fluid is actually providing needed friction for the worn internal parts of the transmission. Changing the fluid and replacing the filter would remove this friction that the internal transmission parts have become dependent on. If you have not been regularly maintaining the transmission throughout the life of the car, you might actually be doing more harm than good if you replace the transmission fluid at this point. For example, putting new clean slick transmission fluid in an older high mileage vehicle could cause the transmission to slip.
If you are not experiencing a problem, have over 80,000 miles on your car, and have not kept up regular maintenance on the transmission, my advice would be to leave the transmission fluid and filter alone. If you are experiencing a transmission problem like those listed above, seek the advice of a qualified transmission shop before allowing your regular mechanic to service the transmission."

Now that you post that, I think I had read something similar to that at one point in time. UGH, what a mess....
