Do you need to drain transmission fluid?
In vehicles, with automatic transmission, the transmission fluid sometimes also acts as a coolant to maintain vehicle temperature. Usually, after the car has traveled over than 50,000km, the transmission fluid needs to be drained and replaced with a new one.
What happens if transmission fluid is not drained?
The transmission fluid has lost its pressure. Difficulty Shifting. A buildup of residue in the transmission fluid can cause the gears to change too fast, too slow, too abruptly, or too erratically. You may also hear grinding sounds or see unusually high RPMs before the gears shift.
How long can you run a transmission without fluid?
However, unlike oil changes which need to happen much more frequently, you can usually postpone transmission flushes anywhere from 50,000 miles to 100,000 miles – or even 150,000 miles in some cases.
Can you add Lucas transmission fix to a full transmission?
Although the instructions say that you can add Lucas Transmission Fix to existing transmission fluid, I recommend checking the fluid levels first to make sure you won’t overfill. So if you’re going to add a whole bottle of Lucas (24 ounces) then 24 ounces of transmission fluid should be removed.
When to do a ” drain and fill ” transmission fluid?
With a drain and fill, you are only removing about half of the fluid from the transmission via the drain bolt, replacing it, and then adding the same amount of new fluid that came out. Then, drive the car for a day or two, drain the fluid again, and replace with new fluid. The idea here is that you’re weening the car off the old fluid.
Do you need oil for a manual transmission?

Why is it important to clean transmission fluid?
Transmission fluid helps keep mechanical components cool and lubricated, whether the gearbox is automatic or manual. Over time, the transmission’s interior components wear down, and tiny particles contaminate the fluid. This could potentially lead to damage. Getting rid of this dirty fluid makes sense, right?
