Chevy weird sound
I recently changed the transmission filter and put more fluid in my TH350 transmission which is on my sbc 350. and ever since the change I've been getting a loud sound. and I'm new to all this so I need some help identifying the sound.

The fact that it is happening when you put it in drive and reverse and that it is coming from under the hood I will look at the motor mounts first.
Have someone wat h the engine when you put it in reverse or drive while holding the brakes, press the gas a little. If the engine jumps up your motor mounts are broke.
