I have a 2015 RDX That just started shifting hard from 2nd to third gear At least I think it’s second and third. I’ve change fluid in the transmission every 15 to maybe 20,000 miles it has 97,000 on the odometer right now and I’ve done at least four transmission fluid changes with Honda fluid. It seems to be shifting hard or kind of shifting hard when downshifting. I also replaced the filter every other fluid change. Is my transmission going out could this be pressure switches? If it could be pressure switches is anyone happen to have any sort of like diagrams or part numbers any help would be greatly appreciated!!!

 

 

I had rough gear shifts. Took it to the dealer last year and they updated the software and it's been perfect ever since. They didn't charge anything as Acura approved the update.

 

There may still be such a problem. If there is a problem with the solenoid, then there must be some kind of code.
