Thank you for your help sir, I took a pair of pics I hope can fix this because I can't find nothing about this issue, wiring harness looks fine, all levels are ok. Any advice??
4030 code still on my diag screen.... Ay each time I try go Rwd or FWD..

Check your wiring from your shift lever to your TCU should be a 5" x 8" x 2" give or take maybe under the seat. If wiring not bad may be your shift lever
Hope some one has wiring prints that can help you.

Guess all connections are good, did you know that gear on display means? Or 4030 fault code.., thank you so much for your help...

4030
Shifter lever malfunction: transmission in
neutral receives forward and neutral together

Seems problem is inside of shifter lever, because a little metal piece is destroyed guess it's making short-circuit, TCU reads many functions at time.. do you have any idea where i can buy this shifter lever..?? eBay??
