    Worked. Put the product in during filter change. Can't tell any improvement, but did not make transmission worse. It went on sale immediately after I purchased product which was very annoying because it was on sale before I bought it but I did not get the discount buying it online, every though the advertised discount was online.

        Comments about Castrol Transmax Dexron/Mercon Domestic Multi-vehicle (ATF) Automatic Transmission Fluid (1 Gallon):

        I used this product to help replace the ATF and filter on a 2004 Chevy Impala Base model with a 3.8L Engine. The vehicle previously had the fluids flushed, but not by machine, but rather a pump, and later the transmission was serviced changing the filter and the fluid but using 2-3 quarts of synthetic ATF and 1 quart of Lucas Transmission Additive which caused the transmission to poorly shift as an intermittent problem. I reserviced the transmission with an new filter and 5 quarts of this product and 3 quarts of Castrol's high mileage ATF as substitute to the Lucas Additive since the high mileage does this as well. The performance of the transmission greatly improved an now no longer has this intermittent problem any longer and cost a lot less than those Synthetic ATFs and additives.

                Does what it was designed to do. Vehicle had fantastic shifting for having 235,000 miles on it. Did have issues prior to fluid change with slow shifting, hard shifting, and strange noise from transmission. This changed when I changed the fluids with clean ones. I have had a dealership change my transmission fluid in the past they did not solve the issue. Removal of the transmission fluid pan and a good cleanings did the trick to solve the noise and shifting issues. Try this yourself but use a few different containers to catch the fluid when you loosen the pan. Good luck.

                          Hi Gowri, tricky question! This automatic transmission fluid would be an ideal ATF for your 1997 Geo Prizm. However, the cause of sluggish shift on your vehicle may be even with the shift solenoids. This may need a mechanic's expertise to determine. I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem.

                          A:

                          Hi Shannon, that's a great question! The transmission is definitely a highly overlooked part of the vehicle and quite an expensive repair. The symptoms you describe could be caused by the fluid or something else. We recommend that you check with a certified mechanic. This link can help you find a mechanic for diagnosis:

                          http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/content_find-my-mechanic___

                          For your vehicle you would need a Dexron VI ATF Part No. 06822. Transmission fluid will, like your engine oil, get dirty and have products of wear in it as well. The recommended service interval for your 1999 Pontiac Grand Am 3.4L V6 transmission is 100,000 miles for standard service and 50,000 miles for severe service. You would also want to replace the filter at this time with Part No. DW-FK292. If you're going to do this yourself, you may also need a repair manual Part No. 38026.

                          A:

                          With respect to your inquiry on the Castrol Dexron/Mercon Domestic Multi-Vehicle ATF - Part No. 03520 the automatic transmission fluid can be changed from time to time in order to extend the life of the transmission. “Changing” the fluid is not the same as “flushing” the transmission, which is a much more complicated job. Flushing should be done every 50,000 miles or so while changing can be done as often as every 10,000 miles. If you are changing the fluid, about 50 percent of the fluid will remain in the transmission. To (flush) remove all the fluid (including the fluid in the torque converter), you must flush the transmission completely.
