I'm Awesome
I have a 99 gmc yukon 5.7l. Starts runs and seems to drive great until it goes in overdrive. Once I get TC lockup I get a 200 rpm surge as if it were to come out of lockup and then rite back in. I can't really feel it but can hear it with the increased engine speed. Does this whenever cruising in OD, every 5 seconds or less.
Thoughts?
