Manual Trans. Thud when shifting

[foghat]

MGW+Steeda tranny insert and SS line+BG tranny fluid=NO THUD. I credit the MGW with the thud elimination

Interesting. Did you do all of that at the same time? This is the first I've read of the mgw getting rid of the thud. Though have seen plenty of posts stating the shifter did not get rid of the thud.

Just wanted to share my experience changing the trans fluid to BG syncro shift 2. Made
a difference .... Not night and day but made shifts a little smoother. It made no difference in the thud.

One piece drive shaft got rid of the thud for me.

The SS line, tranny insert and BG fluid change were done 2 weeks before the shifter was installed. I get no thud in 1st, or any gear for that matter

My experience is limited to jeeps and how they thud. My experience is that its the joints in the drive shaft.

I have the thudding as well. 1-2-3 when shifting under normal loads and into 6th.

Like a charm almost always does it.

To me it does sound like the u-joints have a tiny amount of slop and clunk, or thud, when changing engine speeds between gears at low gears (1,2,3) or big rpm range changes (like the overdrive 6th gear).

I plan on putting the car on ramps this weekend to see if there is any noticeable slop.

No matter what anyone says, I dont consider this normal behavior. If it was, every car would have it. Seems like a tolerance issue in assembly or parts used.

For a bone stock car, I would think that this fault still falls within acceptable limits.

NOW... what about a FI, or heavily modified car? Do we know for sure? I dont think so... and I'd rather have a perfectly smooth drive train before i Install a supercharger that may take this fault beyond operational limits.

Regardless, I'll most likely be dropping my car at the dealer for inspection and resolution.

How severe was the thud before? Seems we have different levels of thudding.

I've been thinking that the one piece DS would possibly fix the problems.

Hard to say, depends on the person. My fiance would always ask what was that when it happened, but it never bothered me. Now that it's gone tho it's nice not having it anymore.

Would you guys say this is better or similar to amsoil? I get amsoil at wholesale so wondering what would be best.

BG is smoother based off people that have ran both. I don't even have my car til the last week of june. I cant personally tell you from experience. Ill be using the BG.

If like to introduce myself, I love my 16 Ford Mustang Gt pp.. But they're have been some issues. Body panel issue clearcoat bubble and a dimple.. The biggest issue at first was the thud. After several attempts to the dealers. Explaining the issue. Along with a noisy clutch engagement sound. Like the forks clapping or chatter. They ignored and tried to say the issue is normal. The clank sound and the drive shaft thud.. They finally replaced the driveshaft, the thud is gone. They found it to have exessive slack. I've been to three dealers. My dealership is by far the worst. The second dealership gave me issues. Even a cursing match I'm not even kidding... Any way to make a long story short. I purchased the mustang Jan 3 2016. It had 170 miles on it. They had it since sept 2015.. I feel with the test drives and finding launch control was active and on after I understood what LC meant when lit. Someone or with the test drives of course didn't break the clutch in properly and cause my issues with the chatter. Anyway it's late. My car is now at a dealership they've had it two days and haven't even looked at it. To see what's up with the chatter. Btw the throw out bearing is making chirping sounds. When clutch is pushed in it goes away. Also been in contact with ford customer service regional managers and it's like pulling teeth. This is a freaking brand new car. I've own a Dodge Charger for 7 years put 210k on it. Only issues I ever had. Tie rods and motor mount and window regulater. Granted tierods a at 130k. This is about ridiculous. I have a lemon claim if I want to follow through. I don't want to but will see after this experience with this dealership.

Ford was directly contacted and they directed replied they are fully aware of the condition and the car is operating normally.
Ford's ignoble response is what angers me and so many others suffering with this problem. What good is a Ford warranty if the company sees product defect or failure as 'normal operation.' This is a clear case of breech of the corporate warranty contract. I see it as an intentionaltort. This could be the makings of a legitimate class action lawsuit.

Amen!!!! Exactly my issue.

I have the same problem and can't get ford to.do shit. They call it normal. I feel there should be a lawsuit..
