How often to change the transmission fluid? My uncle who has a shop said at 3,000 miles as new vehicles put in a very very thin fluid. Then change at 60,000 after that. Seems the trucks last the longest.

If I got a new ride with conventional ATF, I'd change it out within a 1000 miles of delivery for a true synthetic ATF. I'd even pay extra to have the torque converter drained if that was necessary. The best thing that anyone can do for their automatic is to install a high quality synthetic ATF in it.

The 3,000 mile part is definitely not true.

Actually, ATF is not that thin. Looking at the Redline website, their D$ ATF, the viscosity is 34 at 0°C and 7.5 at 100°C. The new thinner ATF they make to meet the newer ATF standard is 30.7 at 0°C and 6.4 at 100°C.

Transmission fluid doesn't have to be changed nearly as often as crankcase oil.

don't just change the 4 or 5 qts. in the transmission pan there is another 16 to 18 qts. in the torque converter.

if you going to change it, do it right, change ALL of it and replace the filter.

50,000 miles is a good time to change transmission fluid if you don't know what the manufacturer recommends. Otherwise, go by manufacturer's recommendation.

If I bought a ride with an automatic transmission, the first thing I'd do is change out the fluid for a true synthetic lube that meets the OEM specs. Transmissions run cooler and are more reliable when the fluid is a high quality synthetic. In the long run, you save money and time because you don't have to change the fluid nearly as often.

Always go by the owner's manual. Never put in anything not meeting the manufacturer's standard or any damage resulting from that use will not be covered. I have pulled a lot of trailers and never had any problems. The biggest thing that used to tear up Auto Trans was people sitting in traffic jams for long periods, hot day, and keeping the vehicle in drive instead of park or neutral to let the transmission cool down. I fall vehicles had a transmission temperature gauge, you would see the difference. Today, a lot of vehicles now use oil coolers, even without the tow package.

Automatic trans fluid, check your owners manual each car differs also applies to manual transmission.Using the proper fluid is the key and not overfilling is vital.

'After the first transmission fluid change in my 1991 Ford Taurus, the transmission failed." Is it auto? If so did you put the magnet back in the bottom of pan? Or did you put enough in?

"How about a 5-speed manual? How often should I change that?"

Depends on conditions.

Some cars need to be changed as late as 3,000 RPM. With others you can change gears as early as 2000 RPM. The automatic transmission in my Powerstroke diesel would shift to top gear at 56 MPH and 1900 RPM down to 1550.

In summary you should change your manual transmission gears so as not to over-rev your engine or lug it.

There's an easy way to answer that question, what does your owner's manual say about how often to change it?? There should be a "vehicle maintenance schedule" section in there that gives you the mileage when different fluid levels needs to be checked and changed. If you don't have one, go to the dealer and look in their books or even to the library and look at one of their repair manuals they have available online.

The last 2 vehicles I bought for the wife the auto transmission was factory sealed, thus there was no way to even check trans fluid level. I heard that Toyota also seals there transmissions so asked a Toyota Service writer who said after they started sealing the trans it lowered their warranty repair cost. I guess that means a lot of people were not using the proper trans fluid, one has to wonder were they to lazy to read the owners manual to find out the correct type of trans fluid to use or did they use a cheap shop that thought they knew more then the manufacture or just did not care.
