We had a performance restriction during one trip. We noticed that the temp gauge was reading well below (20-30 degs) the actual temp. Thankfully, the temp gauge would return to actual temp pretty quick (1-2 minutes), and driving was normal. Our dealer applied a transmission software update, and the issue hasn’t recurred.
We have only done trips above 0 degs, so it may have a restriction somewhere below that temp.
