Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent any electrical issues during the repair.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and pull it out again to check fluid level.
If low, add the recommended transmission fluid (e.g., ATF+4 for Ram trucks) until it reaches the proper level.
Inspect the fluid for contamination and replace it if necessary.

3. Inspect and Replace Transmission Filter (if applicable)

Remove the transmission pan using a socket set and drain the fluid into a pan.
Replace the transmission filter (if applicable) by removing the old filter and installing a new one.
Clean the transmission pan and replace the gasket before reinstalling.

4. Check and Reprogram TCM (if necessary)

Reconnect the battery and use a diagnostic scanner to check the TCM for updates or faults.
Reprogram the TCM if necessary according to the manufacturer's guidelines using a compatible scan tool.

5. Test Drive

After completing repairs, take the vehicle for a test drive to ensure the shifting delay has been resolved.
Monitor for any abnormal sounds or behaviors during shifts.
