Hey Folks! I just completed a valve job with new heads,knock sensors timing belt,p/s pump, gaskets etc. and As soon as i finish to make my test drive i find that my car will not engage any gears. The transmission was taking off in second before i did the valve job. I think it was in limp mode. It shifted fine as far as reverse and once the car got going.But now it doesn't do anything. Can anyone help me troubleshoot this. No real money to spend. But i am lucky to have a junkyard with several same year cars as i. HELPPPP! :o
