CV joint has gotten debris and moisture inside. The CV boot is bad and not protecting the joint. Now its metal on metal grinding. This happens when turning as there is more pressure on the joint. Please fix this ASAP as it can be dangerous to drive on a bad CV joint. While I have seen people drive with a bad CV joint for over 4k miles, it is NOT recommended!

SOURCE: Screeching noise when I turn on my air conditioner or heater

It may just need to be adjusted (it sounds like it's too loose). If the belt isn't cracked or frayed, you should just have it tightened up a bit . If there are signs it is worn (cracked frayed) replace it.

SOURCE: wont rev over 3500 rpm

You should go buy a Haynes or Chilton manual to figure this out. Costs about $15. There could possibly more than one reason for this happening. Anything posted in response could only be speculation.

SOURCE: 1990 1.5l wont rev past 3500rpm's

Honestly I wish I could offer you more info, if it revs now that eliminates the convertor, only I can figure is when you got it to rev you were "blowing the soot out" LOL I hope I have helped you some if so please rate me accordingly.

SOURCE: No power, won't rev above 3500rpms

Transmission fluid level should not have anything to do with engine rpm's. it sounds more like a sensor, maybe a map, tps or even possibly a egr malfunction

I have a 1994 standered nissan altima... when I turn on the car and rev the engine there's no noise... The minute I put the car in first gear and take off there's a rattling noise that increas

Could be a long list of things.
A mechanic would take a test drive and listen under different conditions.
Causes could include transaxle problems, exhaust rattles, worn motor mounts, even valves in the engine.
The difference in idle and moving is a load on the engine and transaxle and the engine shifting position.

Trouble code p1784 on dodge grand caravan

found this on another page.....
Originally Posted by vasau viewpost.gif The vehicle came in with 2 trouble codes and complaint on a transmission shifting.
P1775 Solenoid Switch Valve Stuck in TCC.
P1784 LR Pressure Switch Circuit.
After clearing these 2 codes the van ran normal for about 20 minutes without any issue, but after, the problems came back with no codes.
LR Pressure Switch is always in "Open" position. Must be closed at Park, Rev and Neutral.
Could anyone explain to me how the switch works. Is this the solenoid pack or the LR Pressure issue?The L/R pressure switch should be closed in P/N only. The switch should open when put into REV if the trans is not in limp-in mode. All switches will stay CLOSED if the trans is in limp-in mode. Disconnect the trans 8-way connector at the solenoid pack. Key on scanner hooked up apply 12 volts to the L/R pressure switch pin in the 8-way connector and watch for the switch to change from open to closed. If it does change the SSV may be stuck in the TCC position. You will have to remove the valvebody and inspect the solenoid switch valve to know for sure. The pressure switch itself is in the solenoid pack. If you have an old solenoid pack changing it is easier and quicker than inspecting the valvebody. Perform your diag for fault P1784. I believe the pressure switch is also closed in 1st gear also. Hope this helps.

Sounds like whining noise when i start up then it disappears, what could it be?

If the noise increases if you rev the engine suspect the serpentine belt. This would be more of a screech than a whine. The noise would be more pronounced on a moist morning. It comes from the belt slipping or being misaligned. Try a GoodYear Gaterback belt as a replacement. It has grooves cut into it to reduce noise. Be sure your tensioner is working correctly. Also, the starter can make a noise if it does not disengage properly.

I have a 2002 Pontica sunfire my air condition stopped working a couple of months ago it doesn't even put cold or heat air, it makes a weird nosie, i was wondering what it could be?

If the weird noise is like a coffee grinding machine, the a/c compressor is shot. If the noise goes away when you turn off the a/c, it confirms compressor trouble. If there is a screeching noise when you rev up the engine, it could be that the a/c belt has too much slack and is not turning over the compressor. Heat production and management has nothing to do with the a/c, it is a separate system,

Transmission is not shifting properly on my 2000 nissan frontier 2wd pick up, auto It revs at 3-4000 rpm instead of a nice consitent 2000rpm, revs real high and doesnt change gears intill 20 mph, it doesnt...

You could have a bad valvebody in your transmission or a bad pump in your transmission or your clutches are bad. In any case you have a bad transmission. Please rate my answer.

Ticking in motor, then stops for about a month, then starts ticking again. oil changed. in nuetral it wont rev past 3500 rpm

It wont rev past 3500 in driving?
The governer on these is set to NOT allow a higher rev when car is stopped and not in gear.
Try to change oil viscosity or filter manufacturer.Some filter manufactures put in a bypass valve that kicks in too early.

Gear shifting on 2002 chrysler 300 m

transaxle reset mode page 148 of the owner manual. when the transaxle sensor detects an abnormal condition that can cause damage, it drops the transmission into second gear to protect the transaxle from damage. pull over to the side of the road, shut off the car and restart it. it may go away for a little while and let you drive normally. mine kept getting worse. I took it to the dealer and they had to replace a part that works with the transaxle (not the transaxle or transmission itself). it cost about $900 and took them 3 attempts as the first two replacement parts were bad out of the box.
