I've noticed a low mechanical grinding sound from the shift box on my 99TL when it's in park or reverse. It happened once but now it's happening more often. The car still shifts good and no signs of slippage.

Anyone had this? Is this a sign of transmission problems.

Thanks all for the help.

 

read the transmission failure thread- it list all the known failure signs

check with acura if your 99 is still covered on time limit
