Exclamation NO power in Drive?

When I shift into drive, my Jeep has nearly no power to move forward. It baaareelly goes when I give it gas. Reverse works fine, and I can shift into 1-2 to go forward no problem, but 3 and D don't work. What's going on? I need this car!

Go up under the dash on the passenger side. The TCU is located there. In it's harness, wrapped in yellow tape, is an inline fuse for the power to the TCU. REmove it and inspect it.

Cuz that fuse is inline with the power to the Transmission Control Unit aka TCU.

No power, no shifty.

The line that had the fuse in it has a harness at the end that goes to a silver box under the dash and it wasn't all the way in the box. I bet that silver thing is the TCU.
