2019 Chrysler throws code PD1A8. Drive indicator flashing while going from park to drive. Reverse flashes when going from park to reverse. After placing vehicle in park and back in reverse/drive it will resume to move the vehicle. Could this be a simple fluid filter/ pan change or something more severe?

Thanks for the detailed info. The P1DA8 code on your 2019 Chrysler points to an incorrect gear ratio, which usually means the transmission isn’t responding the way the computer expects when shifting into drive or reverse. The fact that your gear indicators flash and then it works after retrying suggests the transmission is having trouble engaging properly at first.
Here’s what I’d recommend:
- Start with a fluid and filter check. Low, dirty, or old fluid can absolutely cause delayed or erratic shifting. If it hasn’t been serviced recently, a pan drop, filter replacement, and fresh fluid is a good first step.
- Check for signs of metal shavings or clutch material in the pan. That could point to early clutch wear inside the transmission.
- If the fluid looks fine and the problem continues, it may be an issue with the valve body or internal clutch pack—especially Clutch A, B, or D as the code mentions.
- Also consider scanning the TCM (transmission control module) with a proper tool. Sometimes there are additional stored codes that help pinpoint whether it’s hydraulic, electrical, or mechanical.
So yes, start with the fluid and filter—just be aware that if you find debris in the pan or the issue comes back after service, it may be the early sign of an internal clutch problem.
Let me know if the fluid's ever been changed or how many miles are on it—could help narrow things down.
