Flex plate
Have a 4L60 in a 99 TA with about 4500 miles on it, yank 3500 stall,shifts great in all gears and reverse. When the car goes into OD and im at part throttle, the car kinda lugs and I hear a knocking sound at around 50-55. Wondering if the clunking sound it the flexplate bolts loose or a cracked center. If I take the starter off would I be able to see the bolts and check for tightness, a friend say I won't be able to get a wrench in the to check them. Any advice would be appreciated.
