Acura Repair Questions? Ask a Mechanic for Answers ASAP
There are a few different things that could be happening. The most common problem would be that a valve adjustment will need to be performed on the engine. If you can have the codes pulled from the check engine light I can say for sure whether or not the vehicle needs a valve adjust or if the transmission is losing its over drive which is 5th gear.
Autoparts stores ie. AutoZone can pull these codes for free. Once you have these codes please let me know and I can provide instruction on how to perform the valve adjust, when you kindly rate my service at 3 stars or more at the top of your screen.
Thank you and I look forward to helping you through this fix.
