FLUID CHECK MODE VIDEO: youtu.be/_TAhtQIxtHI?si=-TFzfz6TMgXDoaMl
STEPS…
1. Remove fill plug — 24mm shallow socket
2. Just crack open the standpipe bolt - 5mm hex
3. Drain transmission fluid in graduated bucked with the 14mm plug.
Replace washer on plug and reinstall. It will be about 3 quarts. Note volume and put about ½ to 1 qt. more in than drained out.
4. Put jumper in OBD2 connector; jump 4th hole from left on TOP row to 5th hole from left on BOTTOM row
5. Crank truck.
6. Cycle between Park, D and R several times. This cycles the fluid.
7. Put truck in Park, and then cycle between D and N quickly while foot is on the brake, until the D light stays on solid while truck is in P. Now you are in fluid check mode.
8. Put the truck in Park & pull the jumper wire out. Leave truck running
9. The D indicator on the instrument panel will go out on the dash.
Wait for the D to reappear, indicating that the fluid is at the correct temperature. This may take a while if cold.
10. Drain fluid from stand pipe drain with 5mm hex key.
11. When fluid comes out at a trickle/ wobble, the fill level is good. You MUST be parked on level ground.
12. If D begins flashing the fluid is too hot
13. Install standpipe plug and a new washer. The fluid level is now correct.
