2010 Corolla LE transmission whine
Hi,
I recently purchased a new 2010 Toyota Corolla LE auto and I really like it. I have about 2000 miles on it now and just recently noticed a faint gear whine coming from the transmission at around 60 mph. You can only hear it when the radio is off and you really listen for it during the acceleration. It only does it when transmission fluid is fully warmed up after driving for about 15 miles. 2010 corolla uses U341E transmission that specifies Toyota WS transmission fluid. I noticed that 2001 – 2005 Supra uses the same transmission but it requires T-IV fluid which has more viscosity than WS. I wonder if anybody else here noticed this faint gear whine on this car or do I need to take it to the dealer. My other car 2003 Toyota Echo uses U340E transmission and it has gear whine as well, except it is more pronounced than in Corolla, so I an trying to fugure out if this is normal for this transmission or not.
Thank you!
