I will try to help you on this here What is the mileage on it now? is there also an ABS light on with VSA light? The VSS(Vehicle speed sensor) if it failed it will put the transmission in limp mode ? common issue but we need fault codes did you scan it for fault codes? what are they? **Please Let Me Know** **Thank You** **Chad Farhat** **ASE Certified Technician**

No ABS light.

codes? mileage?

81,165 milesI didn't see any codes.34;Limp mode" would explain a lot because right before the transmission started shifting roughly, the car was behaving almost as if it were in neutral when accelerating.

Since the VSA light came on , means there is fault code stored in the pednign files you need that code, based on this code we can pull up a pin point troubleshoot get the codes and let me know without that code, it will be a guess To read the VSA / ABS system you need Acura capable scanner,in other words, the local parts store code reader they scan for free will not do here, can not see the files we need around $100 charge at the dealer to get it scanned snd get a printed out report showing code found Without codes i can tell you the VSS will put in limp mode ,if the speed signal is not beeing seen by TCM module

Ok, thank you. So do I need to take it to the dealership or any repair place should be able to scan it?

The Dealer be to high Any good shop will have scanner needed ,make sure he wors on Acura look at parking lot ,make sure there is a bunch acura outside his place :) Please Read Below How to Get Back in touch with Me You Can Always Come Back to this Conversation and Ask Me any Follow up Question you May have on this Issue (You can Copy this Link Page & Paste it in your Browser when Ready and it will Open up our Conversation Again) or there should be a Tab on your Screen to Add me As Your Favorite Expert I'm Online Daily from 7 Am Till Late Eastern Time Zone Thank You?Chad Farhat?ASE Certified Technician You are very Welcome If you need my assistance in the future, Start your Question with (FOR CHAD FARHAT ONLY) or Go to my profile page You can also add me as Favorite expert for any future questions [http://www.justanswer.com/car/expert-chadfarhat/?rpt=3800](//www.justanswer.com/car/expert-chadfarhat/?rpt=3800)
