Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a level surface and securely lifted if performing under-car work.

2. Check and Replace Transmission Fluid

Check Fluid Level:
- Locate the transmission dipstick.
- Remove the dipstick, wipe clean, reinsert, and check the fluid level. Add fluid if necessary.
Change Fluid:
- Drain the transmission fluid using a drain pan.
- Replace the transmission fluid filter if applicable.
- Refill the transmission with the correct type and amount of fluid (typically Toyota T-IV or WS).

3. Inspect and Repair Transmission Control Module (TCM)

Remove the TCM as per manufacturer guidelines.
Check for loose connections or corrosion on the connectors.
If necessary, replace the TCM with a new unit and ensure proper programming.

4. Adjust Transmission Linkage

Inspect the linkage for any signs of slippage or misalignment.
If adjustments are needed, locate the adjustment points and tighten or realign as per specifications.
Test the linkage operation after adjustments.

5. Reconnect Battery and Test

Reconnect the negative battery terminal and ensure all tools are removed from the engine bay.
Start the vehicle and conduct a test drive to confirm the hard shifting issue has been resolved.
