Subject:
AUTOMATIC TRANSAXLE FLUID (ATF)
DESCRIPTION:
Hyundai automatic transaxles are designed to use Type 7176 ATF. Always use Hyundai ATF+ 7176 (P/N 00212-11100) or Mopar ATF+ Type 7176. DO NOT use any other type of ATF such as Dexron or Mercon.
Type 7176 ATF is a completely different formulation than Dexron III/Mercon, which is the most commonly used ATF. Dexron III/Mercon has different frictional characteristics than Type 7176 ATF, which determines the quality of the shift. If less than one quart of Dexron is used to top-off a Hyundai transaxle, no adverse effects should occur. However, if the ATF is changed to Dexron during a service, the different frictional characteristics of Dexron may cause harsh shifts or clutch shudder during engagement of clutches, especially for the damper clutch.
Type 7176 ATF cannot be distinguished from Dexron by color, feel or smell; consequently, it is not possible to determine if a shifting concern is caused by the use of the incorrect type of ATF.
Type 7176 ATF may not be available at most quick-lube stores. For this reason, many Hyundai customers who have taken their vehicle to a quick-lube store may have Dexron installed in their transaxle.
SERVICE RECOMMENDATION:
If a customer complains of harsh shifting or clutch chatter, ask the customer if a transaxle fluid service was done at a shop other than a Hyundai dealer. If so, please check the customer's receipt to determine if the correct ATF was installed. If the incorrect ATF was installed or no service receipt is available, recommend that the ATF be drained and filled with Type 7176 ATF before continuing diagnosis.
Note:
Check the ATF level with the engine idling in NEUTRAL and the ATF at normal operating temperature (70-90°C, 158-194°F). See TSB # 95-40-003 for further details.
