Luke3204 Posted February 1, 2021 Share Posted February 1, 2021 So my jeep has been making a weird knocking noise inbetween the tranny & motor. I have read it could be cracked flex plate or loose flex plate bolts. Bolts were tight and I couldn’t really tell if my flex plate was cracked or not so I went ahead and pulled the tranny. Gonna go ahead and change the flex plate (if I got the right one). Any other ideas on why my transmission is making noise? It has also been shifting a very high rpm even after I changed the TPS. Below is the new flex plate and old. Could someone also tell me if it’s the right one? Link to comment Share on other sites More sharing options...

coolwind57 Posted February 1, 2021 Share Posted February 1, 2021 Man, I'd seriously consider swapping out those rear freeze plugs while you're back there. Been there, done that. Link to comment Share on other sites More sharing options...
