so everything pretty much runs great now. besides the header leak which im still battling and the leaky carb which is going to be rebuilt soon. this newest noise is hard to pinpoint and discribe. kinda sounds like a grinding but i get a vibration as well. feels like the tranny area. only happens every once in a while and its hardly audible at times. could this be a sign of pending doom to my 700r4? how could a find out for sure?

 

If it only hapens when you start it, and then goes away, you probably have a weak bendix spring in your stater soliniod. If not, might want to pull and check the torque converter cover and see if it's been dented or if somethig is in the bottom of it.
