These are my symptoms for my fault codes previously posted

I am new to forum and I'm guessing my explanation failed to be attached,, my apologies and let me try again. I am having issues with my ML500 hesitating as well as slippage in second gear when I first start it and drive it for the day..it also seems to not know what gear it wants to be in as a whole. Sometimes when slowing down it will downshift hard into ( I'm assuming ) 2nd then 1st gear as if I manually was shifting quickly with my paddles when under normal pretenses it will smoothly downshift so smooth you almost forget you're stopping. Thank you in advance for any help I may receive!

I should have asked this before, were these codes stored in the BAS module?

If so, you must check for codes in the Trans. module and the EGS module.
