Strange grinding noise when starting Jeep

Hi there,

I need some help. When I start my '98 Jeep 6 cyl. there is a grinding noise that occurs and then goes away. It does it when its hot or cold. Now the noise is able to be heard when I idle at a light or something... and the noise sounds like its directly under me

My boyfriend checked it out and says the noise is aorund my torque converter and transmission. we drained the fluid and found some large shavings. He thinks the torque converter we put in 2 yrs ago is going bad already and at that same time the trans was rebuilt. He told me to search the internet to see if anybody else had this problem and may know for sure if it is the torque converter before I buy another one.

Anybody able to help?? please!

I think she meant when starting from a stand still not starting the engine? Or was it only when starting the engine before, and now its all the time? Shavings in the transmission fluid are a sure sign of failure being imminent. Automatics do not like contamination in the fluid especially not metal. Was the transmission cooler flushed throughly when you had the transmission rebuilt? If there was metal in the cooler from the first transmission it could have gotten back into the fresh one two years ago and helped speed the aging process. Just a thought.

or is there a chance the starter is getting stuck and making the grinding noise?

Yeah that what I was thinking but the other things about shavings in the tranny fluid make me think it might be something else.

yes starting from a stand still. I know that the shavings are bad. I believe it was flushed. my boyfriend and I took the trans off adn sent it to a shop to have it checked since my reverse was giving me issues, we took it off to change the torque converter b/c it felt like an unbalanced washing machine at high speeds.

Pull it off and the flywheel inspection cover. Inspect the starter gear for abnormal wear or blueing from heat. check the ring gear for wear as well. If its staying partially engaged there will be plenty of shavings inside the bell housing and the gears should show it too.

Noxian: I think you had a great idea, the starter is were I would start too (pun intended) but shavings lead me to think the worst.
