I have a 2008 GTS for about 5 years now and it’s ran fine until just recently. A week ago the rpm’s started jumping between 2k and 3k once I got 60 mph then it didn’t want to upshift. I tried changing the fluid and it didn’t help. Now I can’t get it passed first gear without doing that. It feels like it’s in limp mode. I connected the scanner and those two codes came up I decided to try to change the fluid pressure sensor but am having trouble finding it and can’t find any resources anywhere. Has anyone had any luck with this?
