1st gear is burnt out in automatic trans have to

low is first gear. sound as if d is burnt that is 3 rd gear. you need your trans rebuilt.

When you pull the shift back to D the gearbag might be seeing N.
When you pull the shift back to L the gearbag might be seeing 2.
Then when you push the shift from L - 2 - D the gearbag might be seeing D.
If this sounds feasible for what symptoms are showing, it might just be a matter of adjusting the linkage between the shift and the transmission.
