I appreciate your time and patience while we are working together on this issue. My goal is to provide you with a pleasant experience and ensure all of your questions are answered. Please reply back at anytime so I can fully answer or address any questions or concerns you may have. _Please download or save any documents or images I may send you as they will automatically expire after 7 days._ The first thing I would recommend to do is check the transmission fluid level and condition. Check for any transmission fluid leaks that may be causing it to be low and check to ensure it is clean (usually pink looking). If the transmission fluid is brown, dark brown or black, it may be time for a flush or a drain and fill. Transmission oil is very much like engine oil that should be changed regularly (just not as often) If not, you may notice an issue with the transmission engaging or shifting into gear like it should. You can also check the smell of the transmission fluid. If its dirty or oil, it will have a foul smell to it which indicates its time to replace or flush the fluid and add some fresh fluid with all new additives and detergents which will help prolong the life of your transmission and help it shift evenly and correctly throughout all of the gears. If these all check out good the next step would be to drop the transmission pan and check/inspect for any excess debris or broken internal parts that may be sitting in pan. If any is found it will indicate an internal transmission issue which will require removal and inspection for further damage. If no debris is found, then it could be a wiring or electrical issue that could be causing the issue that you’re experiencing. Faulty shift solenoid, power supply issue, or transmission sensor or switch that needs replacement. At that point, it may be best to take to a transmission shop for further inspection and a complete diagnoses. If you have not done so already, you could use a scan tool to access the computer on board the vehicle using the data link connector and check for stored codes, pending codes, history and current codes. Sometimes there are codes in the computer system related to the transmission that will not illuminate the check engine light but will assist with the transmission diagnosis and repair you are experiencing. Glad I can help. Please let me know if you have any further questions. Thanks and have a great evening!
