Supertech ATF+4 - is it synthetic and can it be mixed?

From : axel

Q: anybody know if the walmart branded supertech atf+4 is synthetic couldnt find any hint on the label nor on the web. why am i asking the question the last time my transmission fluid was due to be changed i droped the pan removed the old filter and put a new one in put the pan back up and topped the atf off with supertech atf+4. the pan holds about 4qts. i looked up my old receipt and see that i bought 5qts and non is left in my garage so i must have used about all at that time. tranny has behaved without any issues since. that was at 96k miles in sep 06. now i am nearing 120k miles and want to do the same procedure. i was wondering what atf to use this time. the manual calls for atf+3 so atf+3 or atf+4 is fine. all the atf+4 you find are synthetic and then it dawned to me that i 1st of all did not remember what i used the last time nor that i was thinking about what i was mixing at that time. lucky enough i had the old receipts and therefore i know it was supertech atf+4. there are split opinion on the quality of the walmart products and i am not oposed to put something of higher quality in the tranny but didnt know what i can mix or should not mix as i am not performing an entire flush. especially i was wondering if what is currently in there is non sythetic and then i add synthetic what does that do. the entire system holds about 9-16 qts depending on options. so you are only exchanging less than half. last time i used supertech atf+4 and i can use it again but could i also use a higher quality brand that clearly states its synthetic again it will be mixed with what is left in the system after dropping the pan only. maybe all the atf+3 and +4 are synthetic and the supertech atf+4 just doesnt explicitly state it. i found this site http//www.bobistheoilguy.com/ for good discussions on oils and awaiting the account approval so i can post my question but i thought somebody here might know and have an opinion as well. thanks in advance. axel 2000 dodge ram 1500 2wd 5.9l 120000 miles .
