Did you check the trans fluid level? Is the fluid burnt. Any warning lights on?

Customer: replied 9 months ago.
No warning, fluid was low...Added fluid
Expert:  Skyvisions replied 9 months ago.

Did the fluid have a burnt smell to it? When you engage reverse when it's cold will that click in faster than what it does in drive and does it slip fairly well at that point also?

Customer: replied 9 months ago.
No burnt smell.. car has to warm up before going into drive.....car drives forward while in reverse and neutral
Expert:  Skyvisions replied 9 months ago.

Just to clarify you're saying if you have it in reverse the vehicle still moves forward and also a neutral it moves forward instead of sitting still?

Customer: replied 9 months ago.
Correct. The car will move forward in reverse and neutral
Expert:  Skyvisions replied 9 months ago.

That is what I was afraid of. This is an internal failure in the transmission typically a planetary has come apart and has locked the transmission into the gear. It will need to be replaced at this point or overhauled.

Please do not forget to rate the assistance that I provided you at three or higher. If you need any other input feel free to reply and I will get back to you.

Car is in limp home mode
Expert:  Skyvisions replied 9 months ago.

Sometimes if you remove both battery and put a jumper wire across the two cable isolated for the battery for 5 min. then reinstall it will do a hard reset and may take it out of limp mode. But I wouldn't trust driving the vehicle like this with the transmission doing what it's doing.

Customer: replied 9 months ago.
you're saying disconnect the battery and place a jumper wire from the negative to the positive wires for 5 minutes
Expert:  Skyvisions replied 9 months ago.

Yes that is correct. This will reset all of the computers to based learning mode. It will not fix the mechanical issue you're having in the transmission. If the torque converter inside the transmission is not working correctly it will give you the sensation that you're in limp mode or no power from the vehicle.
