I just noticed that my transmission hesitates for up to 5 seconds when I shift into reverse... this does not happen when I shift into drive, only reverse. Once it catches, no problem.

    There is a TSB from Hyundai for the delayed shifting. Take it to a shop and ask them to follow the procedures according to the TSB# below. Here is it:

    A/T - Harsh/Delayed Reverse or Drive Engagement

    Group: TRANSAXLE

    Number: 07-40-009-1

    Date: SEPTEMBER 2007
    Models:
    1999 - SONATA
    2001-06 - ELANTRA
    2001 - SANTA FE & XG
    2003 - TIBURON
    2005 - TUCSON
    2006 - AZERA
    2007 - ENTOURAGE

    Subject:
    AUTOMATIC TRANSAXLE HARSH AND/OR DELAYED ENGAGEMENT INTO DRIVE OR REVERSE

    This bulletin supersedes TSB 07-40-009 to correct OP Time.

    DESCRIPTION:

    If you are diagnosing an automatic transaxle with a harsh and/or delayed shift into Drive or Reverse, follow the Diagnostic Procedure shown below:

    DIAGNOSTIC PROCEDURE:
    1. Check the ATF level when the engine is idling in "N" according to TSB 06-40-016. Adjust the ATF level as needed.

    2. Perform the adaptive learning by shifting from Neutral to Reverse and Drive, stopping in each gear for 5 seconds. Repeat 10 times.

    from here on it needs a diagnostic computer.
