I have a 97 zj with the 4.0. Just recently it statrted making a ohmost knocking sound coming from the transmission area which feels like its coming from the bellhousing(torque convertor area) when I drive at different times itll make the sound and sounds like a rattling and sometimes when i go to certain gears it will go off like reverse or neutraql and makes a real loud knocking sound. Its a replacement trans put in recently. So my question is does it sound like the torque convertor? or what are symptoms of the convertor going as I never had one fail on me. Thanks in advance

 

Sounds more like a cracked flexplate to me.

 

It could be loose torque converter bolts

 

Ok thanks for the help guys, I am going to check both and will let you guys know later tonight. Thanks for the advice

 

Well its fixed now guys thanks for the continuing help for my jeep this site is the best. It turned out to be a combination of the torque cnvertor bolts a little bit loose, the inspection plate a little bent and a few of the bellhousing bolts to mount engine and trans were loose and one on driver side where bracket is was about to fall out. All is well now. Thanks again guys

 

geez. sounds like you need to have a bolt checking party

 

Wow, was this a late night install?
Thanks for updating though.

 

Yeah it was atwo day R&Rwith me and my father and we were up late too many molson xxx for that install.. Would have found my problem out sooner or later when the trans is laying on the ground woopsies

 

Just all the raw horsepower of the 4.0 that made them rattle out of place...

 

I hear ya'. It's supposed to be water while you're working, alky when you ain't.
