Experiencing Torque Converter Issues

[tmontague]

I went to the dealership on the weekend and grabbed their Trans fluid @ $7-8 per liter. The Echo takes 3.1L so I purchased 4 and ended up returning the last bottle.

The price was actually decent so I just stuck w/ Toyota fluid. I didn't drop the pan, the front bolt heads are pretty rusted so I just drained the old fluid and added new.

The old fluid was in pretty good condition it seemed. I never really had bad shifting or noises so nothing new changed there, maybe slightly smoother shifts over all.

The one thing I noticed was a quicker warm up engine temp than before. This seems odd and unrelated except that I noticed on super cold mornings last winter that the transmission would take an extra 5 mins to shift out of 3rd after the blue coolant light turned off.

I'm hoping the new fluid helps the trans/engine warm up quicker and get out of 3rd gear faster.
