Transmission slips when shifted into reverse on 2003 Hyundai Santa Fe

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. Zee
