Transmission downshifting hard from 2nd to 1st in Sport shift mode
Tonight i was taking my TL out for a rare spirted drive in the rain and coming out of a corner at about 4k rpm's i went wide open on the throttle and the transmission downshifted into 1st gear and redlined for about a second then shifted back into 2nd... I know our TL's shift between 1st and 2nd even in sport shift but should i be worried? Maybe it was a fluke because of the rain & VSC system? 2006 base model, I've replaced 3rd/4th pressure switches, filter, and I run redline synthetic D4 ATF. All preventaive maintence no issues so far.

Since you already have Redline D4 in the car it's kind of a pita for you to switch out to dw-1. It is my feeling that the Honda transmission being the way it is should only be using Honda transmission fluid. I agree that red line is good stuff. As is Mobil 1, royal purple and all the other Boutique stuff. The one thing about my car that I never change is the fluid running in the transmission. When I change my transmission fluid I always stick with DW 1. I heard from several mechanics whom I trust that the Honda transmission should stay with Honda fluid. I would switch out fluid immediately to dw1. See if that helps your problem. If not get it in for a transmission check up immediately. Unfortunately if the transmission is going to go then there's nothing you can do about it.
