Answer
Hi Jimmy,
The quickest way to start the process of fixing the trans is to get a fault code readout of the controller's memory. It probably has store a 4-digit code which will be the start of a diagnosis. An Autozone parts store will often do that for free, or try another parts store; and independent shop will do the readout for less than $40. Once you get the number, ask what it means, what is recommended to do, and the price. Then write back with a follow-up question and tell me the fault code number and we can compare notes with the shop manuals.
The down-shift is likely to 2nd gear not regular drive, and if so, that is called 'limp-in mode'. It does this when a problem is detected which if allowed to go on will cause unnecessary further damage.
