The dealer shafts you for real they charge you $200 to exchange what is in the transmission only so like 3 quarts worst rip-off in the world I would not worry about it if you want to change it do it I changed my car Lexus ES330 with 200,000 miles original transmission oil no issues at all and I did my 3rd gen 4Runner with 450,000 miles (unknown if it had been done before but it was very dark) with no issues at all so I think you'll be fine I would much rather have clean fluid in there then Super all black nasty stuff that's been in there from the factory.....

I'm sorry guy I don't mean to thread hijack but does anyone know the transmission pan gasket part number? I got one from RockAuto part number TOS 18736. It says Toyota truck 4 Speed 98 through 03. I assume it is not the correct one but maybe they didn't change them....
