I am trying to get some advice on a diagnosis for a transmission problem i'm experiencing with my vehicle? It's a manual transmission and the sound i am hearing is when i shift gears is a loud whirling grinding sound. It's really loud in 2nd 3rd and 5th and doesn't stop.
View 1 RepliesMy girlfriend has a 2001 Ford Escape 3L, 6cyl. When accelerating there is a loud high pitch whistle/whirling sound. The sound varies with the amount of throttle you give it. More throttle = louder whine. Doesn't seem to do it when idling or coasting. What that could be? I'm about to remove the belt and take a look at the drive belt tensioner and other pulleys.
Just checked pulleys and tensioner and the tensioner seems fine, a/c pulley spins smooth and free no play, alternator spins smooth no play. The belt needs to be replaced. I wouldn't think this would cause such a load whistle under acceleration. I would expect it to do it all the time if it was the belt. I'm looking at the water pump pulley and belt too and they seem ok as well.
I have a 92 chevy pick up 5.7 with 159,000 miles. The truck runs and starts great but shortly after I bought it 3 years ago it developed a sort of misfire at higher rpm's, it's fine if I drive it normally but if I try to pass someone it will downshift then fall on it's face, (spit,sputter and slow down). some times I can feather the accelerator and it will come back again. I normally don't drive the truck in the winter but this week I was forced to use it and the cold weather is seriously affecting it, it took forever to get it up to 70 mph after getting on the highway. once up to speed it will do 75 all day without an issue.
I've replaced the plugs, wires, pulled the throttle body and cleaned it as the port for the pcv valve was plugged solid with carbon. I have not replaced the cap and rotor as they seemed to look fine. I have not checked the fuel pressure because it will break the tires loose upon take off and I don't think that would be possible if the pressure was low, would it?
I have a 1993 Chevy Silverado, 350, 2WD. It has a 4L60E transmission. I just started having a problem shifting from 1st to 2nd. When accelerating the RPM's go way up and won't shift until I let off the throttle. Then it shifts into all other gears normally.
If I accelerate slowly. it will shift into 2nd at about 16 MPH. It will then shift into all other gears normally. I have replaced the Throttle Position Sensor, flushed the transmission and replaced the filter and fluid. This made know change in performance.
I am now suspecting that it might be the 1-2 shift solenoid. The check engine light is not on and everything else works fine.
I have a 98 Chevy truck with a 4L60E. It has no second gear. I was sitting in park for about 10 minutes with the engine running, then put it in drive and it never shifted into second. It felt like it went straight to 3rd. I played with it manually until I figured out I had reverse, 1st, 3rd, 4th and torque converter lockup, just no second gear. My acceleration rate was medium and when I reach about 27-28 mph it would shift from 1st into 3rd. It has 230K on it so I rebuilt it with all the typical parts - frictions, steels, band, sun shell etc., still no second. I then pulled the pan back off and replaced the spacer plate and put in a shift kit. While I had it down I put a corvette servo in and did an air check. It worked fine. I could feel the band tighten.
Both the 1-2 and 2-3 solenoids checked good at 23 ohms. I swapped their positions to see if it would make a difference. I also checked to make sure the 1-2 accumulator piston wasn't stuck in its bore, the spring was new from the shift kit. It was fine. Put it back together...still no second gear. When I originally pulled the pan off for the rebuild, the pan was free of any debris and was very clean. I then drove it a couple of miles to a local transmission shop. They put their scan tool on it and drove it around the block. There were no codes and the ECM was calling for second gear. It doesn't sound mechanical since almost all the parts have been replaced, rebuilt or inspected that affect the 1-2 shift. It sounds electrical. Is there anything I have missed?
My dad's 1996 Chevy Silverado will not shift into hi gear. The truck starts up fine and he can drive it but for some reason it won't shift into hi gear. Him and I are clueless as to why it won't. He has a 1996 Chevy Silverado, 6.5 liter V-8 automatic transmission, and its a diesel. We really want to fix the truck ourselves so we are trying to avoid taking it to a shop.

View 7 RepliesI installed a new motor in a 1990 chevy Silverado about 5 months ago. every time i start it there is a loud clunky noise which goes away after about 1 or 2 minutes.I took apart the exhaust.. why does #2 cylinder have rust on the exhaust port not black soot?
View 1 RepliesA little less than a month ago my wife's old 1999 Mustang had the tires replaced. Since that time there she has noticed two new sounds:The first is whirling/grinding sound coming from the front right wheel that comes and goes. The second is a low, loud groan that seems to come from the front of the vehicle when the brakes are applied. The groan varies in intensity but seems to always be present when the brakes are applied. The groan is not unfamiliar to anyone that's driven an older car, but it is much louder than I have ever seen on any other car (on the other hand I usually drive a Corolla so it may be normal on a V6 Mustang ).
The first sound seems to have been reduced but not eliminated since I followed the advice in this video below and pushed the plate behind the wheel back a bit with a screwdriver. Now it is only audible when the engine is off and the wheel is spun (in other words, when it is sitting on a jack and the wheel is spun by hand), but it is still there.
I took it into the shop where the tires were purchased and mounted. The good people at the shop did rotate and balance them, but both noises remain.
I looked at the calipers and discs and everything seems in order except (possibly) two things. The discs have rust around the edges not unlike the ones in this photo below and I have no clue if that is normal or a problem. The rust is present on all wheels and only the one makes that noise, so I think that may not be the source of the sound,. On the calipers some substance (paint?) is peeling off, but otherwise they look fine and again the same is true on all the wheels so it seems that is unrelated to the noise. I have not been able to get a look at the pad, so I don't know what condition they are in.
Other information: The serpentine belt was replaced a few days after the new tires were installed. The radiator was flushed at the same as the belt was changed. They also threw in an oil change and all the fluids checked at the same time. The tires are new Michelin Defender size 205 /65 R15 and all 4 tires are new. The engine is a V6 and the transmission is automatic.

I have a 98 Silverado, 2wd, 5 liter V-8, 180,000 miles. Occasionally, my truck will lose power. Driving down the road I lose speed and cannot accelerate. When I depress the accelerator the motor does nothing. This happens at any speed from take off to highway speeds. When it begins to happen I lose speed slowly for maybe 30 seconds then the service engine light comes on and the problem gets much worse. Sometimes it will sound like it's back firing but the sound is muffled. This seems to happen more often in damp weather but it can happen in dry weather too. And it doesn't always happen in damp weather. It happens in the morning or afternoon. Auto Zone put their tester on it and a code comes back for O2 sensor but the guy didn't think that would cause the trouble I'm having.
View 4 RepliesMy wifes 2006 mountaineer V8 overheats. She says itll only do it sometimes after the truck has been warmed up. She will come top a stop and the temp will spike and she will get a warning light then it will go back to normal and be fine. When the temp spikes she hears a loud whooshing or whirling sound coming from the motor which I supposed is the fan? Could it be a bad thermostat or waterpump?

View 14 RepliesI have a 2001 Chevy half ton 4wd. It has the 5.3L, 4L60E transmission, and a 246 transfer. I am having problems with shifting. if I out the truck in drive, the trans will wind out in 1st gear and not shift. I then pull it down to 2nd and it will shift. When it comes time for third gear, it will not shift at all. It just simply revs until it catches up with the speed at which the truck is rolling. I thought it was a bad tranny as I smoked one and replaced it with a used one so we rebuilt the tranny and it still does the exact same thing. Also the speedo is not working but the odometer is on. Don't know if its registering anything but its on. I have also checked every single fuse and maxi fuse in the engine compartment and the drivers side panel.

View 4 RepliesI applied brakes while car was moving slowly, less than 10 mph, and heard loud grinding sound coming from left front as car stopped. Shifted to reverse and car barely moved, less than 1 foot, which was accompanied by the loud grinding sound, then stopped. I could find nothing interfering with the wheels but did find pieces of brake pad on the ground along the path the left front wheel had followed. The left front wheel appeared as if the calipers were holding whatever remained of the brake pad and/or backing tight against the rotor. brake pad fell apart on 2002 at 43,561 miles...
View 19 RepliesSo my 2010 Camry LE with manual transmission has developed what I figure will be an expensive problem. It oftentimes grinds when I shift from 1-2. If I pause between the two it's fine, but if i just go straight to 2nd it grinds about 75% of the time so that I have to go back to neutral, let out the clutch, reengage and THEN go into 2nd gear. What could cause this? I'm stumped. There's no issues with any other gears and it does the same thing if I got from 3-2 also. It's to the point where I try to just skip using that gear. It's got about 135k miles.
View 7 RepliesA friend just had a transmission line pull out of his radiator and blow fluid all over everything.
How do these lines work? Are the kind of like the fuel lines that just plug in and are held in my a retainer clip?
Does the whole radiator have to be changed to fix it or can the "fitting" be turned out of the radiator and replaced?
Looking at the line that is still in the radiator, the fitting looks like a large hex nut at the radiator with a thick rubber washer on the outside.
I have a 2001 Chevy Malibu ,I have noticed a whirling sound coming from my steering wheel whenever I am turning. I am wondering what could be the cause and should I get it checked out.
View 6 RepliesI have an old base model 2001 Silverado, so manual everything. Here's my problem-- the air direction control knob (feet, defrost, face, etc.) is stuck on defrost. Literally stuck. Obviously, the knob attaches to and is supposed to turn a metal rod that then changes the direction of the air flow, but the rod will not turn at all...I even detached the knob and tried to turn it with a pliers! The climate control and fan speed knobs both work. What might be causing this?
