Acura Legend 1994 LS, sedan, 185000 miles, automatic, last week the VSS was changed and now the car runs at 3000 rpms at 60 MPH and the fuel comsuption increased. Car was running 21 MPG and now 16.5 MPG. Dealer says that everything is OK.

Is there a place to find a table of the RPMs vs MPH? Any suggestions why this problem is happening?

Thanks

I would be interested in why they replaced it and then did they replace it with the exact same part or an alternate part. I suspect it is the latter. They know it is a problem but I suspect they don't make the original VSS for the car.

Thanks for the reply. The VSS was changed because the D4 light was blinking and the speedometer stopped functioning.

I do not have any way to know if they changed using the right part or an alternate.

Any suggestions will be appreciated.

Are you sure the car is shifting in to all of the gears?

Apparently the car is shifting to the 4th gear but the rpms are high and the gas consumption is up.

I do not know if the 1994 acura legend has an overdrive and if it does it is engaging or not.

Thanks

Your manual should be able to confirm but that must have an overdrive. It really sounds as though the next gear is not engaging.

This problem just start occurring. Whenever I go outside to start my car in the morning to let it warm up while in park. The rpm's go higher than normal and my cars sounds as if I pushing on the gas and accelerating. The gauge on my rpms goes between 2 and 3 back and forth constantly. I just had an oil change, could it be my coolant or another problem? I also notice it takes a while before my heat comes on, its not until the car is in drive that the rpms settle to normal and the heated starts to work.

Thank you in advance for your response!
