I have throttle body. Seems strange that it runs so smoothly until it hits exactly 2400rpm and above. Then the 50rpm jump is at the same time you feel a slight reduction in speed. Lasts for a second or so and then drops back for a second or so etc.
Last tune up was maybe 6k ago and generic parts were used.
If you are cruising at 70 on level grade and the torque converter lock goes in and out, how much rpm change would there be in and out?
