First of all they are the FRPP gears not motive. There is a little whine when i let off the gas and coast, but it makes a lot of noise when downshifting to slow down. It doesnt really do it when i downshift to pass someone but if im comming to a light and go down from third to second if the light changes it sounds like something is rubbing. The guy who installed has done gears before and did them on his wifes mustang so im pretty sure he knew what he was doing. Is it normal to have a little noise at first or should i have someone else look at it. I talked to the guy about the noise afterwards and he said that i might need to have my transmission fluid flushed but i asked my friend and he said that the fluid should have anything to do with it.

 

it sounds like what happens to me when i down shift like that....its just the synchros i believe...and if i make u feel better...i have stock gears

 

Any easy way to fix it....its loud and annoying as hell.

 

I experienced this with my tranny also....the Royal Purple Synchro-Max Tranny fluid (provivded by MT) greatly reduced the tranny noise for me...

 

Downshifting to slow down? That's why you have brakes. You must like changing your clutch alot. As for the sound, if it's from the trans it's just the gears and sycs, if not the trans...???

 

Ummm, lots of people use the engine (downshifting) to slow down. How does that ruin a clutch? I thought this was normal practice for you stick guys?

 

i use a bit of both to slow down...i like to keep it in the power band at all times..even while braking...just incase i have to speed up to avoid something....

as for the noise...do the simplest thing...change the fluid...and see if that helps...if it doesnt..then ur synchros are going bad....

 

I see you have an 04 GT, which means you should still have a warranty. If the dealership doesnt find out you have gears (which they probably will) then the tranny should be fixed under warranty (assuming thats the problem).

 

they shouldnt have to open the diff...if its all in the tranny then it wont matter

 

Yes, but they should be able to tell as soon as they get in and drive the car. If thats the case then they will void that warranty Im sure.

 

ive heard that most people wont mechanics will look over that stuff...but that only what ive heard

 

Some mechanics **** retendant butt monkeys about the smallest things voiding a warrenty. But then again there are the mechanics that don't really care and would do the same thing.

 

Um, do you have an automatic or not know how to drive a stick? Downshifting is normal practice to save wear on the breaks and keep your power up while still slowing down. It was like the third thing I learned when I was 15 and learning to drive.

 

They may say that but it is illegal to do that. A dealer has the burden of proof in showing that a modification caused the malfunction in the car. I learned this a couple years ago when Downey ford bitched about my CAI. I brought this up I was only 17 at the time too, LOL hadn't gone through business law yet like I am this semester, and I'm learning alot by the way lol. Anyways they almost **** a brick the manager of the maintenance department hates me now because I know my rights unlike 90% of people out there...

 

Yep that is true. So lets say they blame the gears on the problems. Whats the next step for you to prove them wrong? If its court then he isnt going to go to court with it.

 

You can always try another ford too if they give you problems they wont know.

 

So i guess replacing the fluid would be the first thing to try right?

 

Try replacing the fluid first but did this just start happening after the gear install? If it was happening before then it is probably the syncros but thats strange if you just noticed it when the gears were put in. As for ford, they bitch about almost every little thing. You just have to show them you know what your talking about and you should get your warrenty work done

 

Yea it used to whine a little when coasting at higher rpms but now it sounds almost like its comming from the transmission.

 

+1, except i had just turned 16 when i tried manual out on the old sixer. After awhile that car was so easy to drive... going back and trieng now the clutch is about 20x as hard to push down... and the gearing (2.73's out back) means you just stay in third forever and always.

 

I use to think the same thing, there is a law but....the one guy with an 05 GT, that had udps' on and his alternator took a crap. They gave him hell and when he brought that law up, the buy bitched him out even more, i believe he was one of the service managers, and said "take it to court, i bet FORD has deeper pockets than you will ever have" which is true. but he also stated that he,guy with GT, knew someone that worked at FORD and said that they look at it, determine if they can warranty it, but...the big dogs in FORD can say yes or no. So....if the dealership does it, and then try to get the big dogs to reimburse them for the fix, they can say no and the dealership has to take the loss, that's why they are **** about aftermarket parts. Also they can flag in the system, your problem with your vin so if you go to another dealership, they will know. I've heard of FORD installing parts on your car for them to warranty the aftermaket part, but i've heard to that if it messes up, they will fix it, but if you take it to another FORD dealership, they don't have to warranty it, their dealership didn't install it, but sometimes they will.

It depends on where you go, if you buy your stang from that dealership, they are more to help you, if you didn't....who knows. Some are cool and some are dicks.

Did they add friction modifier to the rear?
What gear oil did you use?
So was this his second time installing gears(girlfriends car 1s)?

If it's your tranny, then i can't see them saying no to fixing anything, if they look at the rear end and notice it's just siliconed on or non ford gasket or something different, unless he's not to keen of a mechanic, then they might check out your gears, they just have to count the teeth and do the math and that will give your gear ratio.

Goodluck with it...

 

No dont replace the fluid yet. Take it to Ford first under warranty, if you replace the trans fluid, then I guarantee they will try to dick on on warranty.

If they want to charge you to fix it anyway, then try changing the fluid.

 

It's essentially a product liabilities case with a contract in dispute. Luckily for the consumer in a product liabilities case the burden of proof isn't on the consumer it's on the professional in the field in question (in this case the dealer). So you don't prove them wrong they have to prove themselves right. As far as is it worth going to court over no but it's worth threatening them with it.

 

True but ford won't let it go to court. You won't let it go to court. It's not worth it for either party. Usually they just fix the problem. On a seperate note ford mechanics are mostly idiots who's to say they'll even notice it has gears? They never mentioned to me about my gears when my tranny gave out on me. They just got me a new one.

 

the secret for me has always been to keep going up the chain of command one guy at a time. Stay calm but make sure they know how pissed off you are and how much you'll talk to your friends and the community about their unfair and illegal service practices. Hand them a printed copy of the Magnusson-Moss warranty act and ask them to point to a section and show you where in the act it shows that they can deny your claim without proving that the modification CAUSED the failure. Then, all you have to do is open the case in small claims court (this makes the dealership the defendant and bars lawyers from entering the proceedings as counsel), get 3 estimates for repairs from your local shops and serve the dealer. You'll probably make 500 bucks on the deal.

 

+1, because, you know, I totally already... knew that...
