'93 G10 4.3L "ticks" only when in gear.
 

Hello everyone. I'm new to this forum (but not to forums in general) and I've got an issue with my van. I got it from my father in-law a few months ago and I'm working away on getting it fixed up. I posted a YouTube video this morning showing the problem. If you'd could check it out and give me some feedback, I would greatly appreciate it! This problem might be old news to some of you, so I apologize if this has been covered to death in the past. Feel free to reply on this thread or make a comment on the video itself. Thanks everyone!

Have someone sit in the seat with the brakes on while in gear and then you get under it from the side to try and place where its coming from.
I am gonna go with the tranny. There could be something worn in there or in the torque convertor. When was the last tranny fluid filter change? Might be worth getting that done as well as a once over for that noise.
Localize the tick better and let us know where it sounds like its coming from.

Thank you for the response, I really appreciate it! I'll give that a shot tomorrow and let you know what I come up with.

Strange how it also does it when you rev the engine in park. Thinking when the engine/trans moves a bit something is tapping.
