Do Manual Transmission Cars Not Need Transmission Fluid Changes?
2 Answers
Manual transmissions do require transmission fluid changes. The service life of manual transmission fluid is longer than that of automatic transmission fluid. Generally, automatic transmission fluid needs to be changed every two years or approximately 40,000-60,000 kilometers, while manual transmission fluid can be changed every 3 years or after driving about 80,000-100,000 kilometers. However, the specific interval depends on the usage condition of the transmission. Below is relevant information about transmission fluid: 1. Transmission fluid serves functions such as cleaning, lubrication, rust prevention, and heat dissipation. Regular transmission fluid changes can clean and lubricate the gearshift system, extend the lifespan of transmission components, ensure normal transmission operation, and make gear shifts smoother—potentially restoring that new-car feel. If transmission fluid is not changed for an extended period, besides affecting operation, the fluid's performance will degrade, lubrication effectiveness will decrease, leading to accelerated wear of transmission components and increased likelihood of malfunctions. 2. Daily maintenance of the transmission should be performed routinely. After driving for a certain period, check the transmission for any oil leaks and inspect the condition of the transmission fluid. If the fluid level is insufficient, it should be replenished promptly. If the fluid color darkens or the quality deteriorates, it should be replaced immediately.
I used to drive a manual transmission car for many years, and I think many people believe that manual transmission fluid doesn't need to be changed, which is actually a misconception. Manual transmission fluid requires regular replacement, typically between 60,000 to 100,000 kilometers. My first car, which I forgot to change the fluid, started having stiff gear shifts and loud gear noises after seven or eight years. Later, upon disassembly and inspection, wear was found, and the repair cost me over a thousand yuan. So now, every two years or before long trips, I check the manual to confirm the replacement interval to avoid bigger problems caused by delays. Changing manual transmission fluid is simpler and cheaper than automatic transmission fluid, costing just around a hundred yuan. Neglecting this over time may reduce the transmission's lifespan, increase repair costs, and affect driving smoothness. I recommend everyone develop the habit of not skimping on this small expense to avoid bigger troubles. Don't regret like I did; regular checks are always right.
