slight trans whine...

[eldawg4100]

i have a 92 seville, 67k... 4t60-E trans... trans (im almost positive) makes slight whine noises at idle, the trans performs perfectly though, i just changed the old fluid out, twice via drop pan and re-fill... any ideas what it could be? I think it is a bit more prominent when its real cold outside...

Check your fluid level when hot and idling. I've changed trans fluid before, and measureed how much hot fluid I took out and replaced it with the same amount of room temp ATF. Turns out that ATF expands a lot when hot, so replacing the same volume with cooler fluid actually overfilled my tranny by .7 qts. I would not have even looked except that the trans began to make a strange, whinning sound not long after the fluid change. I checked the fluid level and was surprised to see it overfilled since I was so careful. I removed the excess fluid and the whine went away.

the 4t60-e in my 92 bonneville whistled at idle.

it also couldn't hold the TCC very well.
