You have a shorted engine harness, this is not common but it does happen, heat and engine movement cause damage to the harness, this is most common on hi miler cars and vans, the only way to fix it is to start by looking anywhere the harness rubs, that is where the damage occurs.

It sounds like you broke the sun gear shell in the transmission. This is real common on 4L60E. The transmission will have to be disassembled to fix it. If this is what is wrong it will have no reverse and hold 1st till about 30 and then skip 2nd, right to 3rd. Then never shift in to 4th.

Take it to a transmission shop that has a Tech 2 scanner. The tech 2 scanner will not only scan the transmission but can also recalibrate the shift points. Other reason to why it wont shift under WOT it low transmission fluid pressure so check the fluid level and have a pressure test done on the line.
The 4L60E is a great transmission but there are some things that don't work well with them like some shift kits. The ECM is program the shift points which get's messed up if done wrong. best upgrade on the 4L60E was to swap out the servos for corvette servos or after market performance one's all for under $100.00 and in most case better then a after market shift kit.
Good luck and hope this help. take care not to burn up the transmission.

this sounds like you have a problem with the electric fuel pump sticking, that would be where i would look, when u turn the key on with the windows up do u hear a humming noise for about 3 seconds? if not the fuel pump is the problem.

check the electrical part of your ignition switch . this is common to burn out and is easy and inexpensive to fix .does not require anything to be done to the mechanical part of the switch and key.
