2006 srt8 7.0 engine.

It happend when I was racing on this day I heared a knocking sound at idle comming from front of the car it goes away when I drive. It happend at wot high rpm car suddenly idles high & gear wont engage with a sound of broking things down in the engine. Stoped the car switch it off & back on it idles well but when switching to drive rpm goes up little around 200-300 then goes back to normal but car wont move even in reverse what could it be? Im suspecting a broken flexplat?

Sounds like your transmission is slipping bad-Do you have a check engine light? How's the transmission fluid and condition if okay bring it in and have it pressure tested to find out more what's going on.

No codes at all. Gonna check gear oil tomorrow cause my model does not have a dip stick. One more thing Iis that I dont feel anything when switching gears except rpm movement. I never had any trans problems before except the torque converter which I changed 3 months a go cause it was broken cause my car has a 500+ rwtq.

When you really beef up the engine you always end up breaking the weakest link you need to beef up the whole drive train etc. Otherwise who knows what breaks next its design for the stock set up.
