TRANSMISSION OIL (Or) POWER STEERING OIL(TQ)

It seems like you're asking about the choice between transmission oil and power steering oil. Both of these fluids serve different purposes in a vehicle's operation:

Transmission Oil (Transmission Fluid): This fluid is used in the transmission system of a vehicle. It helps to lubricate and cool the moving parts inside the transmission. It also facilitates smooth gear shifting and ensures the proper functioning of the transmission. Transmission fluid should be checked and changed according to the manufacturer's recommendations to maintain the transmission's health and performance.
Power Steering Oil (Power Steering Fluid): Power steering fluid is used in the power steering system to assist the driver in turning the steering wheel with less effort. It helps to transmit the driver's steering input to the steering mechanism, making it easier to control the vehicle's direction. Regular maintenance of the power steering system, including checking and changing the fluid, is important to ensure proper steering function.
If you're referring to which fluid to use for a specific purpose, it's essential to follow the manufacturer's recommendations outlined in your vehicle's owner's manual. Using the correct type and grade of fluid is crucial to maintaining the performance and longevity of your vehicle's components.
