I have a very hi pitched whine anytime I accelerate: if I keep it level in 5th gear its not too bad , I'm sure its the turbo but I don'tknow whats wrong

syncros ..worn
chipped teeth in cogs
worn bearings

two ways out
repair current gearbox or.... fit used gearbox

Not sure, but 5th may be a lock up torque converter rather than another "real" gear. If so, solenoid for this may be bad, or torque converter may be bad. Have you changed the trans fluid and filter?

sound like main shaft bearing assuming it is manual( if it comes on all the gears)

if it is automatic it must be your torque converter bearing

If its having difficulty moving through the gears it could be a transmission issue or the turbo could be bad which would also cause a bogging down situation.

Does the pitch change and/or go away when the transmission changes gears?

I'd check the U-joints first. Then, check for low gear oil level in the gear box.
Also examine it by draining the gear oil to see if it has any metal fragments in it.
If it does, you probably have a bad bearing or something else coming apart.

Mine has a high pitched whistle at high rpms and I can't figure it out. But mines def not the tranny. I'm thinking it's a vacuum line somewhere. It's a 97 2.3l manual. The colder it is the louder...

The most reliable and tried and true method is to check the transmission oil. Check it for...
1. Correct level
2. Right colour: a nice light red. (or somtimes yellow) not brown
3. Smell, it should have a not unpleasant smell, if it smells 'bad', it is starting to break down and will attack the friction material on clutch packs and brake bands.
4. Remove the transmission oil pan and check it for flecks of friction material, metal filings and pieces of rubber.
If any of these things are present, you have, or will soon have a transmission failure. The whine could be the transmission oil pump, the gear set is known to to come incontact with the pump body causing whining noises and creating metal filings which cause the transmission valves to stick..

Hi Pullerwife,

I have a few suggestions for you,

First of all, check your air filter, make sure its clean, not clogged, and doesn't need to be changed.

I don't know how handy you are, but if you are fairly handy, check the idler pulley bearings, if your not, have a shop check it out, as a last resort.

Power steering pump/fluid being low is also a possibility, but thats usually more of a lower pitched whine then what you describe.

You say once the vehicle is warmed up, the whining stops. Does Weather seem to be a factor as well?

Hope I've helped, and don't forget to rate.

hi my name is nathan .......now...... what it sounds like is #1 (I have to hold it in place til I get to second gear) that can be that your shift linkage is worn or out of adjustment,pilot bushing is Badly worn,shift fork,lever and or shaft is bent or worn,or your bell housing is misaligned or just loose...i have a few more ideas on why it is jumping out but those are the main ones now about your whining gear noise#2( The whining sound starts low pitched in each gear then gets higher pitched as the rev's increase) you may have worn gears maybe or it could be just that your transmission lubricant is incorrect or inadequate.
