1. Check the transmission fluid level again. Make sure that the vehicle is on a level surface and the engine is running when you check the fluid level. If the fluid level is low, add fluid to the transmission.
2. Look for leaks around the transmission pan. The transmission pan gasket can sometimes develop a leak, which can cause fluid to drip out of the transmission. If you see any leaks around the transmission pan, you will need to replace the gasket.
3. Check the transmission lines. The transmission lines carry fluid from the transmission to the radiator and back. If a transmission line is damaged or kinked, it can cause fluid to leak out. If you see any damage to the transmission lines, you will need to replace them.
4. Check the torque converter seal. The torque converter is located between the engine and the transmission. The torque converter seal can sometimes develop a leak, which can cause fluid to drip out of the transmission. If you see any leaks around the torque converter, you will need to replace the seal.
5. Check the input and output shaft seals. The input shaft seal and output shaft seal are located at the front and rear of the transmission, respectively. These seals can sometimes develop a leak, which can cause fluid to drip out of the transmission. If you see any leaks around the input or output shaft seals, you will need to replace them.
If you cannot find any leaks, it is possible that the transmission has a leak inside. In this case, you will need to take your vehicle to a qualified mechanic for diagnosis and repair.
