Well N281 is way out of spec for sure. I can't say for sure it will fix your problem, but it's sure way out of spec. Seeing as this Solenoid controls brake B3 in gears 1-4 and reverse it very well may solve your problem. I'm no expert on these things, just a novice and figure I can test the components and replace them way cheaper than any mechanic. If it was my car I would roll the dice and replace it. The worst thing that can happen is you are no better off then when you started, but you will have at least gained some knowledge.If it fixes the problem you can pat yourself on the back and feel good you saved thousands of dollars that a dealership would have charged to replace the entire tranny. On a side note if you are using the inexpensive Mercon V fluid you can just dump it and replace with little trauma to the bank account. If OEM fluid and it's new just drain it into a clean container and re-use it.
