noise from flexplate housing

I had my engine replaced and now after 15 minutes of driving(its more frequent when hot). i will get a noise from the area that sounds like a sawzall cutting into a metal hollow can. changes with speed and goes away when i let off the gas. doesnt always occur. comes and goes. sounds like a vibration. no lift kit


Thanks
4.0l engine btw


Any ideas?

exhaust leak... or possibly one of the bolts that holds the cover on is missing/loose, allowing the cover to vibrate.

Same thing happened to my Jeep. It sounds like one of the torque convertor bolts are hitting the transmission inspection plate. It's annoying, mine doesn't go away, doesn't matter if hot or cold. I bent that plate to a position so the noise isn't as loud, though. And this happened to mine after I replaced the engine, too.

Bump,


So halfway through winter it doesnt make the horrible noise so its def temp related. I did notice that I can here a circular grinding noise as i hit the brakes(weight shifting forward) in the tranny tunnel.

could of the jabroni forgotten a spacer? or could it be a bad pilot bushing? i have limited experience with autos

Is your trans pan bent? Possible that the filter is hitting the pan.

got an oil change yesterday. I did take a peek and it looks like the pan is bent inwards. Your saying the motionless filter could make a noise heard for 50 yards?
Care to elaborate?

It doesn't need to move much in order to make a racket. Just a vibration on that tin will cause obscene noise. It's possible that the shop used a trans lift and used the pan instead of the bell housing when removing engine.

It doesnt explain the grinding noise as the drive train shifts forward.

Illl bend it back out when i replace the tranny fluid and filter this spring. I have some slipping when its warmer out.

Have to checked your trans mounts? I would imagine if they were bad enough it would allow the trans to shift while under strain.
