Going up a steep hill lost power as hit incline slowly made it over the hill got to the next hill and engine revs normal but truck not going anywhere. It seems like the selector is selecting all the gears but no movement in wheels in any gear.
Do you

Good morning,

This definitely sounds like the clutch is slipping not providing power to the rear wheels.

You need a new clutch.

I attached a YouTube video for you to view of the procedure.

1. Remove slave cylinder from transmission with hose attached.
2. Remove transmission as previously outlined.
3. Insert clutch disc pilot tool.
4. Loosen pressure plate retaining bolts one or two turns at a time until spring pressure is released, then remove pressure plate and disc.
5. Reverse procedure to install, noting the following:
a. Torque pressure plate retaining bolts in the diagonal pattern shown in Fig. 1 to 13-20 ft. lbs. on B2600i models or 16-24 ft. lbs. on B2200 models.
b. Torque slave cylinder retaining bolts to 12-17 ft. lbs.
c. If the flywheel was removed for resurfacing, torque flywheel retaining bolts for B2200 models in sequence shown in Fig. 2 to 71-76 ft. lbs. or to 67-72 ft. lbs. in sequence shown in Fig. 3 on B2600i models.

This could be a transmission issue but more then likely this is base engine related. Meaning it is fuel, ignition, or air flow related.

Let's start with checking fuel pressure while driving up a hill and go from there.

If you have not replaced these parts recently, I would start with these which is basically a major tune up.

1. Air Filter
2. Fuel Filter
3. Spark Plugs
4. Ignition coil

Then we need to check for a plugged exhaust as this will hurt air flow and cause low power when going uphill.

Depending on the fuel pressure we may need to replace the pump but let's check the pressure first.

Lastly we need to check for a vacuum leak.

Let's run through all this and go from there. Thanks
