Greetings, just registered. Seems like a very nice forum. I have a question about automatic transmission fluid change. Toyota sets no interval in the scheduled maintenance, I have an '06 LE and is this true or am I missing something? Every time I have my oil changed they try to talk me in to a flush, which I always refuse. But what about a simple drain-and-fill? My fluid is a nice red/pink, leaks/consumes none whatsoever, never had to add a drop in the 40,000k+ miles I have had it, bought in 2011. Shifts fine, no problems. Thanks
