![]() So, in addition to cooling the transmission and preventing internal gears from grinding, the transmission fluid in automatic transmission vehicles also powers the transmission.īecause automatic transmission systems generate a lot of friction and heat with regular use, the fluid in automatic transmission vehicles will naturally breakdown and dissipate over time. In automatic transmission vehicles, this movement happens from a hydraulic system that is powered by the force of pressurized transmission fluid moving through the transmission system. In manual transmission vehicles the clutch and gears are manually moved by the driver of the car. HOW TRANSMISSION FLUID WORKS IN AUTOMATIC TRANSMISSION VEHICLES While the transmission fluid in manual transmission vehicles doesn't tend to naturally break down on its own, loose parts or impact from road debris can cause leaks and low fluid levels. Transmission fluid runs between all the gears in your manual transmission and running metal-laden fluid through metal gears can end up causing untimely wear.Īnother thing to look out for is a transmission fluid leak. If you have a manual transmission system you want to keep an eye out for contaminated transmission fluid, and specifically transmission fluid that appears to contain any shards of metal from worn bearings or synchronizers. Manual transmissions may use manual gear oil, or transmission fluid specific to each vehicle make and model. The type of transmission fluid used in manual transmission systems will largely vary depending on the make, model, and specifications outlined in the vehicle owner's manual. The transmission fluid also keeps the gears lubricated and at cool operating temperatures. ![]() In manual transmission systems, transmission fluid is primarily used to prevent overheating and the premature wear of gears. HOW TRANSMISSION FLUID WORKS IN MANUAL TRANSMISSION VEHICLES The transmission fluid exchange process differs between an automatic and manual transmission, but the end result is the same: a more efficient transmission, better fuel economy and the avoidance of transmission repairs caused by neglected transmission fluids.Ĭall or come into your neighborhood Firestone Complete Auto Care store today for a transmission fluid change and read on to discover how transmission fluids work. During a transmission fluid exchange, our tire and automotive service professionals will remove virtually all the old transmission fluid and replenish it with new transmission fluid. In many cases, a transmission fluid exchange is due every 30,000 miles or 2 years.įirestone Complete Auto Care stores across the nation offer manual and automatic transmission fluid exchanges. I’ll take it if for drain and refill every 30k miles and see how long this one lasts.By keeping up with the your vehicle's recommended transmission fluid change schedule, you can keep your transmission in good working order and decrease the likelihood of costly transmission repairs down the road. The Jasper trans is guaranteed for 100k miles or 3 years. I ended up buying a rebuilt trans from Jasper and having the dealer install it. I stated that with the regular service that I had been paying for, it should last the life of the car. They asked me how many miles I expected to get out of an automatic transmission. I was upset about the transmission failure. I suspect the transmission problems in the 2000-2002 period had a lot to do with it. It seems Honda changed their recommendation sometime between 19. Later I checked my records and found that sometimes I had received a power flush and other times I had received a drain and fill. I had requested power flushing at every service. I showed them my copy of the advertisement that was on their counter in 1999 that recommended power flushing. ![]() They acted like this had been the recommendation forever. I was told that Honda does not recommend power flushing. ![]() The fluid had a burnt smell and there were metal filings on the magnetic drain plug. I took it to the dealer for a diagnosis in July. ![]() At 239k miles the transmission was slipping in the 1-2 upshift. I had the transmission fluid power flushed (or so I thought) at 40k mile intervals. I’ll share my experience about my '98 Accord 4 cyl (bought new and now with 245000 miles). ![]()
