Whining coming from Tranny...I think

Hey folks,

Ok 97 2.5 128k. 5 spd.... I just got back from about a 30 mile round trip mostly highway (50-65 Mph) and when I got back into my town and slowed down to 40 and some stop lights then to 30 and more stop lights I could hear my trany whining like it does when its in reverse. The whining is a lower pitch than in reverse and gear 1,2 and 3 whine but not 4th but it comes back in 5th gear. this just started and I'm worried, and broke. I dont know if its the clutch, syncros, low fluid....WTF

oh I left it out of gear and reved up the engine and no whine. clutch feel the same and power from gear to gear is the same and well as going thru the gears the feel is smooth and normal


Any help is always appreciated.

Thanks everyone

While I havent checked anything yet mentioned above due to the holiday I did have a question about the above remedies (not that they are wrong) but does the throw out bearing or low fluid just...... happen.....I didnt do anything catastrophic (or did I) while taking a short trip. I feel like tranny fluid would just drip out or a bearing would wear out slow...not just Happen... I D K...... I'm just thinking out loud....

Throw-out bearing can indeed just go out. same as ungreased ujoints. Your front drive shaft still spin when in 2wd. The front axle in ingaged withing the t-case.
It can be the ujoints squealing. Easy check and fix there.

Also...the throwout bearing Is enternal of the transmission housing so I'd start with checking the u'joints first.

Check your differentials...i recently checked my rear diff for the first time since ive owned and it and i could not even feel any fluid in it when i reached in with my finger. My jeep was making a whining sound in 2nd and 3rd under heavy acceleration but i never really thought much of it til i checked the diff fluid. I put in a quart and a half of 75w-90 gear oil to fill it back up! The whining is now gone and im thankfull i didn't destroy my differential
