I'M HAVING PROBLEMS WHEN DRIVING IN "D" WHEN IT GETS INTO THE FOURTH GEAR.(ABS/TLC LIGHT GOES ON) . THANK YOU

Answer
You're not likely to damage the transmission, but continued high rpm operation may damage the transmission or overheat the exhaust.

You're okay to run the rpm's as high as the red line, but for continued driving, you should probably limit the rpm's to under 4,000.
