Have Transmission Questions? Ask a Mechanic for Answers ASAP
Good morning and welcome to JustAnswer!!!
If all the lights on the shifter are coming on then somethings wrong and there will be DTC's(codes) set in the shifter module.. The first step to repairing your issues is to retrieve the codes wit a scantool and follow the diagnostic test for each active code..
Can you have the codes read and post them here so I can get you the information you need to get it repaired?
I wouldn't purchase a scantool just to read your cars codes because they cost 4,500.00 If you don't have one then you will need a shop to retrieve the codes for you.. Once you get the codes post them here so I can tell you whats going on..
Keep me posted,
