1997 C280 Question!!
 

I just purchased a 1997 C280 with 160k on it. The car runs and shifts great. The only issue I am seeing is for about the first minute of driving the rpm's gets over 2,000 before shifting out of first gear. After the car is warmed up it shifts out of first gear between 1500-1700 rpm's. Is this just a warm up issue or is there something more?

Thanks,

Luke
