Hi
My Mitsubishi Challenger has 2 problems.

1. When you start in drive the second gear does not engage and engine loses power after a few meters car starts to jack as if requesting for more powerful gear.
When that happens I am forced to enter 1st from" L" Gear to "2" then to "D" when vehicle reaches 40KPH

2. When driving up hill the Gear does not uplift to more power full gears, even if I apply to much force on the accererator the RPMs do not inrease at this point

What can I do at this point.

Remove positive terminal for 10 second and see if it clears the check light your car might be in limp on mode or low power mode
