Will hitting the transmission oil pan affect the transmission?

Carefully check for oil leaks, as leaks can have an impact. Here are the relevant details: External oil leaks: Pay special attention to whether there are oil leaks at the front and rear crankshaft oil seals. A cracked, damaged, or aged front crankshaft oil seal, or wear on the contact surface between the crankshaft pulley and the oil seal, can cause front crankshaft oil leaks. A cracked or damaged rear crankshaft oil seal or a too-small oil return hole in the rear main bearing cap that obstructs oil return can cause rear crankshaft oil leaks. Front and rear oil seal leaks: If oil seeps from multiple areas such as the front and rear cylinder head covers, front and rear valve lifter chambers, oil filter, and oil pan gasket, but no obvious leak source is found, inspect the crankcase ventilation system, clean the crankcase ventilation pipes, and check if the PCV valve is malfunctioning due to carbon buildup and gumming.
