Edit Reason: Make more complete
)
I have a 99 Chevy Tracker with a 1.6 liter engine and a five speed manual transmission and four wheel drive. When in 1st, 2nd, or 3rd gear and revving high (around 2600 to 3000 RPM) it has begun making a whirring or whistling noise. The noise is not present in fourth and fifth gears. Is there something wrong with my tranny? If so, what should I do about it?
Also - Just had this in the shop to replace the rear transmission seal. It was not making the noises before I had the shop replace the seal. They said they also replaced the rear lower bearing.
Thanks,
Joe Tracker

ok, you posted evidence. I missed this.
4th gear is not a gear at all, (magic) it is 1:1 direct drive and 5th is actually overdrive. and is great symptoms this.
gee the shifter tip , plastic tip is bad as all are this old and now rattles like mad.(shifter tip ,metal to metal failure does)
rear transfer case seal right> (i bet)
They said they also replaced the rear lower bearing.
(on what ?_)
the rear seal is part transfer case. unless they pulled the transfer case to get the 5sp box actual, did they?
I guess, u-joints bad too.
a U-joint can fail and if ignored, the vibration (huge) beats the seal front of it to death.
be clear on what they touched,
there are many seals here.(5)
front of 5speed pinion
rear of 5speed, seal
front of transfer case seel
rear of transfer case seal upper to rear prop shaft
tranfer case lower to font prop haft seal.
the casing from 5sp to xfr case , center empth case (adptor) is dry,
there is no oil in the center case.
there is open always drain hole in the bottom of the center case that if drips oil we know 1 of 2 seals above are bad.
when the 1,2,3 gears make noise and tranny fluid is full up to right filler hole plug . is it, never ignore this at 60k mile tune up, it's just simple check.
at noise rest your HAND on the shift lever top (firmly down) does the NOISE END??????????????

I hope you guys not mind a side question here.
> ..at noise rest your HAND on the shift lever top (firmly down) does the NOISE END?
What are we trying to diagnose here? Just asking as mine gives a noise if I rest my hand on the shift lever. When no pressure on lever, no extra sounds heard. Just asking as I know mine is old and 2nd gear synchro is definitely near end of life.
