I got home yesterday, about noon. When I shifted to park I noticed the CEL. So, on/off 3 times and P1754 shows up. I look it up find out it is a stuck TTVA and check the forum. Go outside to run it around the block and sure enough, high RPM shift out of first. Check the forum again, start shopping, see the pictures of the ate up gears, order part. Over night delivery got screwed up and I need to meet my son for an Av's game tonight, so today I hop in to run some errands (I figure it is still drivable) and what do ya know, it is shifting fine. Clear the code with the CTS2. Is this usual, could it be something other than the TTVA. The new part is showing up so it is going in, I just wonder if it could be anything else. No other codes were present.
