When I am doing about 65mph the shifter is really vibrating. I am not sure if this ok or how to fix it if its not. Also, I was talking to a buddy and he asked if when driving when I push the gas does the shifter move well I never looked but I did last night and it does move a little. Is that ok if not what can I do to fix it?

I am new to the whole having a real car thing and am sure a lot of what I am noticing is just the way it is and not bad I just want to make sure if there a problems I fix them now before they become a costly problem.

Thanks

My buddy had same thing on his 93 cobra. High speed shifter vibrating. He ignored it and one night while shifting the thought he broke the shifter and couldnt get the car to go into gear.

Long story short it was very minor for him. I would remove your shifter boot and check the shifter it self it may be coming loose and eventually from the vibrations will come all the way lose.

If its not that then it may be something more. I would start by removing the shifter book and looking making sure your shifter is secure.

Alright man if u go and u check ur shifter and its tight or u tighten it and u still have the problem im gonna tell ya its most likely that ur drivin with a out of balance flywheel...i had the same exact problem and i changed the flywheel and it went away...ur shifter moving when u give it gas is usually the case of a worn motor or tranny mount so check those too...preferably change them to polyurathane mounts...if u have alotta power the shifter may still move a lil when u give it gas...but alot of movement is usually the mounts. good luck bro

WHAT??? :happyhapp :blink::blink: An out of balance flywheel will not cause the shifter to vibrate. It will cause the whole car to vibrate.


srt4to935.0...... the shifter rattle or buzz you are hearing is the bottom of the stub(where your handle is bolted to) that is seated in a plastic cup on the shift rail, is worn out. The plastic cup, over time, becomes very sloppy allowing the gear chatter to transmit up thru the shifter and cause the handle to buzz or rattle. The fix is to either replace the plastic cup or add a shim to the cup to tighten the tolerance.
Remove the shifter from the transmission and pull it straight up. You'll see the cup on the rail I am talking about. Either go to Ford and get a replacement cup or find a thin flat washer and put it down in the cup between it and the ball on the bottom of the stud. This will "tighten" it back up and should stop the rattle.
The handle moving under acceleration is the gear set in transmission. It is NORMAL and will not cause ANY damage.

I don't think it's necessary for things to get personal, everybody. We all are here to help someone with their problem and all opinions are open to discussion. Let's get back to the topic at hand and help the guy out and not make remarks towards anyone else's thoughts. Keep it between the lines.

Alright...I am tired of going back and forth with you in PM's...time for a little basic Flywheel 101 and let others chime in and tell me if I am wrong or not......

Because the flywheel is bolted to the crank, an out of balance flywheel will cause the whole rotating assembly to shake. This in turn will cause the drivetrain and vehicle to shake as well if the imbalance is bad enough. Now before you go and argue this point, let me clarify one more point for you.... Ford only made a 28oz counterbalance or a 50oz counterbalance for the motors that are in mustangs since 1964 1/2 until now. That means that if you have a 5.0 motor, it'll require a 50 oz counterbalance(assuming you don't have a custom balance on your motor). If you took a flywheel from a '60's or '70's vintage mustang, which is a 28oz counterblance and bolted it to your 5.0, it'll shake the whole rotating assembly, drivetrain and car SITTING STILL, when you bring the rpm's up.
Since the original poster said "When I am doing about 65mph the shifter is really vibrating" and nothing about the engine shaking, it cannot be the flywheel. This means it can only be one of two things.... A. His shifter tower assembly is loose or
B. the plastic cup on the shift rail is slap wore out.

Now does it make sense? :laugh:

If something is out of balance, it'd do a lot more than just shake the shifter, the whole drivetrain would be rattling and quaking. We've had numerous people comment about something being out of balance and they felt it throughout the car, even the balancer being off will drive you nuts.
