Whine when downshifting (when the revs go up)

[rage707]

Hey Everyone,

Im looking at an 03 GT that whines when you downshift. Once the revs go up it whines pretty loud for a second till they drop. This normal for this year stang? The guy could have done aftermarket gears, as it has new control arms and springs, etc.

Where is the whine coming from? I had to replace my idler pulley once; it whined badly (bearings were shot).

It sounds like its coming from the tranny or rear end. Almost the sound straight cut gears make. My 94 didnt do this, but I figured it might be something with the t-45 tranny.

stock gears?

Well, then, not your idler pulley! I'll shut up now and let someone more knowledgeabe answer the question. Good luck!

This is normal, if your downshifting to slow down then yeah your going to hear
the gears whine abit. Mine does this all the time, Im not concerned what so ever.

my 2002 5-speed does it, i was worried about it at first. but then i was told it was normal, so i dont mind. it does it everytime i downshift while slowing down when the rpm's climb, so i wouldnt worry about it

Does it have an aftermarket shifter on it?

SOme shifters amplify the tranny whine.

T-3650's are notorious for whine. Mine has done it since day #1

I like it when mine whines... sounds kinda cool

Its normal... put an aftermarket shifter ont here and it gets louder

 

[01SN8K]

it should be the tranny i believe the 3650's have straighter gears than all the other ford trannys. mine whines loud enought in 1st and 2nd sometimes it is mistaken for a blower.

Yea mine did the same thing but they just replaced the trany for gear grind and now I have no whine or grind. The true test will be this winter when the temps are cold.

if it's not the stock shifter i would say it's normal, there is a guy on e-bay that has a gasket set that can quiet them.

 

[jrc_03_gt]

I think its the input shaft to the trany.

mine whine's too scares me to death. I have bad luck with mustangs and bad tranny's
