We need to know which is happening, we can do so by checking the condition of the transmission fluid, it could be burnt which we should do a service.

Next we should run the codes.

That wont cause the transmission issue. we will need to get a sample of the fluid to see if it smells burnt please let me know. if it needs a transmission rebuild this video will show you the steps to remove it. (similar job)
