This is the first case we have on Genesis (BH) 4.6 litters shock shifting. since this kind of model for example if the gear box has a problem the only thing we do is to diagnose where does the problem and there are only three option to replace to Mechatronics E module + valve body,check the engine system and to replace the automatic gear box assembly.
How to check automatic transmission shock shifting

= P0729 Gear 6 incorrect ratio.
TCM sets this code if the value of input speed (Turbine speed) is not equal to the value of output speed,when multiplied by the 1st gear ratio, while the transaxle is engaged in 1st gear. if this code is outputted,check the engine system first
