I was working on a headlight mod to make them flash back and forth and then i was driving around right after i put it all back to stock and about 1 mile later i couldn't get it into 2nd and now my speedometer and odometer don't work. then i drove it around a little more then i couldnt get it into 1st, 5th, or reverse and I can't get it into 4th sometimes. I can only move the stick up and down from 3rd to neutral (in the center of neutral only) and sometimes 4th. and everytime i tocuh the car it shocks me. I checked all my conections and its all back the way it was and nothing is touching.

Does anyone have a clue what it could be?

Why would it be locking out those gears?

I have been driving it around for about an hour now and some gears will work sometimes but others wont. normally about 1-2 gears wont work while the others do then once I stop or change speed some differecnt gears wont work.
