What type of parts store automatic transmission fluid can be used in a 1999 Hyundai Elantra?
"any brand of dextron III will work"
This is wrong. Use only the approved Hyundai ATF, SP-III. If that is absolutely not available in cases such as myself (in Alaska with no Hyundai dealer within 700 miles), ATF+4 should be fine (exceeds specs). Dextron III does not meet the specifications of the Hyundai ATF, and Hyundai transmissions are very picky.
I agree with the above. Dextron by itself is not enough. A chart I have recomends factory fluid,but if not available,Mopar makes an additive that should be added with Dextron.
A 2005 Hyundai Elantra with less than 100,000 miles is still eligible for coverage under the manufacturer's warranty. Transmission slip could be any number of things, but the cheapest fix is to ensure the proper transmission fluid is being used. If the recommended fluid is being used, then the best solution is to take it to the dealership and request a warranty repair.
There is a special funnel designed to fit into the transmission oil dipstick tube. Fit the funnel to the tube and pour the transmission fluid in. Pour it slowly, because if you leave a drip of ATF on your paint, the paint will suffer damage. ONLY EVER ALWAYS use the automatic transmission fluid from your Hyundai dealer. Using an incorrect-specification ATF ***WILL*** destroy the clutch packs in the transmission and require a $$$$ transmission replacement…
How long should you wait before changing the timing belt and the automatic transmission fluid on a 2007 Hyundai Elantra 1.6L DOHC engine?
Use only "SP III" approved fluid, according to Hyundai. (Due to the particular friction modifiers required). Look for a fluid stating approved for "SP III" on the back of the bottle. Failure to use the specified fluid will lead to failure of the clutches inside the transmission, requiring a costly rebuild or replacement of the entire transmission.
