Advice for neglected 2007 Sienna transmission

[twolittlebroncos]

Here's an update.

I did a drain and fill (4 quarts) with Maxlife. I also set up my Scanguage II to read the transmission fluid temperature. I realize the Scangauge might not be the most accurate way to measure the temp., but it's what I have and I don't plan to do any towing. With that said, anyone know what temps I should expect to see? With 80* air temps yesterday in stop and go traffic the Scangauge measured TFT at 210*. Is that reasonable or high?

Do we know where the AT fluid is being sampled in the tranny?

For stop and go traffic, I don't think it's too bad.

BTW, for the upcoming summer, consider having the cooling system flushed unless you know for sure it has been done before you acquired the vehicle.
