Engine shaking past 4000 RPM when not driving.
 
This problem does not come up when driving, however when parked and on neutral or speed when i spin my RPM up, past 4000 engine starts shaking like crazy feels like earthquake in the car.

Transmission is not good i know that for fact, but would it still be problem on neutral?

P.S. prior to 4000 it does not give any shaking at all. And when driving i sometimes go to 6000 RPM without problem..

The engine is limited to 4000 RPM in Neutral and Park. It's a safety feature, to keep you from revving it to 7000 RPM and then engaging the transmission.

You are up against the limiter

It's also there to prevent the motor from over revving out of gear and causing catastrophic failure. My brother had a '71 F100... Coming off the highway went from fourth to first... Destroyed his 390

Back when trannies could outmuscle engines. One problem we will never have to worry about with our Bulls. :rolleyes2:

Exactly, motors may have been close to bulletproof, but those trannies were bulletproof. I remember the carnage too, broke 12 out of 16 valves, three valve heads welded to the cylinder walls and the rest found it's way to the oil pan and cooling system. He called me up and said, "hey my truck stopped running." I drove down there and coolant was dripping out the exhaust pipe. I looked at him and said he's f'd

All I have to say is Ford C6 transmission.

The better question is why in the hell do you feel the need to rev the piss out of the car in neutral/park? There are safety equipment in place to stop people from doing stupid things........ this being one of them.

I see the import kids with their fart can mufflers doing this all the time to impress their idiot friends. I just laugh, smile, and think "what a moron".
