[6pack] ATF Fluid..... non Triumph

[Vsnively at aol.com]

Bob,
 
   The biggest enemy of ATF is heat. That's the main reason most  of it is 
synthetic today. Synthetics were developed post-WWII for jet engine  
bearings. We could build turbines, but the oil technology couldn't support the  
lubrication requirements (heat and high RPMs).
  If it's a dark red or black, time to change, regardless of factory  
service intervals.It's only $100 for a change. A rebuilt tranny is $2500. 
 
Thanks,

Does ATF fluid change from red to black over time? I've  got an 07 Mazda3 
with 40K miles that runs great. At the last oil change,  the quick lube 
guys 
were saying that the ATF fluid needed to be changed  because it was no 
longer 
red and was therefore dirty. Nothing in my manual  about ever needing to 
change ATF............... Are the quick lube guys  just looking to pad the 
profits? Or should ATF stay red even after  40K?

Thanks
