04 Monte Carlo 3400 eng. 70k mi. No CEL present in the info center. I do not have a scanner to watch real data.
While highway driving this week, I noticed that while at cruising speed, the engine rpm's would jump about 2-300 rpm according to the tach. After seeing that I began to listen more carefully and indeed the engine rpm was erratic and not steady. Under load the rpm is steady.
My first thought is to change F & F in the trans thinking the TC was slipping.
My question to the experts is : Does this sound like a familiar (minor I hope) problem?
