Default Changed tranny fluid at 9K, it is noticibly darker than new fluid. Please help! 4EAT

I changed my tranny fluid to synthetic at 9K. The old fluid is a darker red (almost brownish) when you place the two next to each other in a glass. Also, I noticed that the old stuff has a stronger smell to it (although not burnt, it smells 'used'). I have only done three launches on the car in the 9K miles, and dont race. When checking levels with the old fluid, the fluid always appeared transparent on the dipstick (so appeared clean), but agianst new fluid it appears dirty. There are no metal shavings or particles. Is this normal?

sounds pretty normal to me....been workin on automatic transmissions for about 5 years now (just not subaru 4EAT or 5EAT) but generally yes it sounds normal....the dirtyness (sp?) comes from normal geartrain wear (very, very fine metallic particles...) and friction material off of the multi-disc clutches.....ATF generally acts as a strong detergent and anything that it can trap in the oil it will what doesnt get trapped usually sits in the bottom of the pan.....the "smell" you are smelling is from the high amount of heat that planetary gearsets and tq. converters generate when operated at any speed.....what does it smell like when you hard-boil an egg?...same thing goes for oils....ever smelled what used Manual tranny fluid smells like after its been used? you think atf is bad at 9k? try smelling 75/90 or 80/90 that is on its first change in 20-30k....... its some foul smellin stuff tho i cant really think of a comparison for what it smells like...

i would conclude normal wear if no particles or shavings in the pan... and just like the person before me stated (sry i already forgot ur name lol) if you are skeptical about your personal findings take it to be analyzed and theres no mistaking normal for abnormal....

My OE ATF was black at 30K. Switched to Amsoil ATF and it's still black at 56K. At the moment I'm waiting to get my transmission back from IPT, it had a bearing replaced, most of the cluthces were burned and overall the tranny looked used for its age.

I don't race, launch, or abuse my car. Basic Stage 2 power level daily driver.

Hopefully you won't have to go through what I'm going through ATM.
