Manual Transmissions: Most vehicle manufacturers recommend a transmission fluid change between every 30,000 to 60,000 miles. The problem is fluid contamination which occurs over time as the synchronizers, bearings and gears in the transmission wear out. The resulting metal particles then float around in the lubricant.
Can changing manual transmission fluid be bad?
There is no risk to changing it if you use the proper oil. There is a huge risk if you continue to use it without changing, as it has some wear particles from the gears and synchronizers. Also, many of the additives have lost their power to react chemically with each other and the gears to provide protection.
When should manual transmission fluid be changed?
Most manufacturers recommend that manual transmission fluid be changed every 30,000 to 60,000 miles.
Is manual transmission fluid change necessary?

Should I change manual transmission fluid after 100k miles?
The simple answer is yes. But service intervals for new vehicles can exceed 100,000 miles before this needs to be done.

Why You Should Never flush your transmission fluid?

Does changing gearbox oil make a difference?
