View 12 RepliesSilverado :: 1999 Chevy Shifting Really Hard In First And Second / Revs Up To About 2000 RPMs
My truck was intermittently shifting really hard in first and second . I drained the tranny fluid and installed a new filter and replaced the fluid, I also changed plugs and wires. Tranny fluid is at the top of the hash marks on dipstick when hot and in park. When I come to a complete stop my engine 5.3 litre v8 revs up to about 2000 rpms but the truck takes off slowly like the tranny is slipping it is worse on an incline. If I dont come to a complete stop it shifts fine and takes off with good power. After it shifts to second it shifts normally and drives fine. tranny fluid looks clean and does not smell burnt. Also when driving on the highway if I am going 45 mph and punch the gas it wont rev past 2200 rpms like it is lugging down. when i shift thru gears manually there is no slippage what so ever and when in park engine revs to 6000 rpms no problem. Also tranny is a 4l60e

I have a 1999 chevy silverado 5.3 4wd w/ tow package. I bough it with 30,000 mi. It has always had a hard shifting/clunk after long drives or sometimes short ones that involve a lot of elevation. Oddly, if I stop and shut the car off for a minute or two the hard shifting stops, but eventually starts again. The truck now has 160,000...still with the shifting issue. What is this and with this many miles is it serious?

View 4 RepliesPassat (B5) :: Steering Shakes Badly?
I took the car in for a steering vibration/jiggle problem (and a 60K mi service), and the dealer replaced the axles/driveshafts under the powertrain warranty.
It seemed fine when I drove back home, but recently I've been noticing the steering shake again. If I remove my hands from the wheel, it jiggles and pulses to the left and right by itself. Whenever I turn the wheel off center left and right, (while moving; mini-slaloming, I suppose) the wheel resistance pulses back and forth... it isn't creamy smooth. And finally on the freeway, the front end seems to hop... it's rather disconcerting.
Can any of this be cured by the powertrain warranty... or am I looking at some suspension/steering work?
Ford Super Duty (1999-2016) :: 2008 F350 - 4x4 Low Light Flashing And Truck Surges Badly At Low Speeds
I'm having a strange issue with my 2008 F350 6.4. I have only had this truck for about 2 months now. Every time it gets wet (from rain or a carwash), the 4x4 low light begins flashing, and the truck surges badly at low speeds. When I get above about 25 MPH, the light stops, and the truck runs normally. At the next stoplight, it happens all over again. After a couple days of dry time (?), the truck is back to normal (until it gets wet again). I have found a couple of old threads involving some similar symptoms, but they were never resolved on this forum (that I could find). I believe the transfer case selector motor has been replaced at some point, as it has a Dorman brand sticker on it. I wouldn't think Ford would use Dorman parts as original equipment.

I have a 95 940 turbo that shakes really bad when braking. things I have done so far are.
1. Replaced all four rotors.

The shaking is so bad that the gear shift moves back and forth when braking.
Passat (B6) :: Engine Shakes Badly And The RPM Keeps Bouncing
Ok so here's the thing. I put an intake on the car. But the engine shakes badly and the RPM keeps bouncing. There is no air leak. Is there any vag-com programming that needs to be done for the intake to work since it is going to be different than the stock one? t is a 2.0t engine.
View 11 RepliesGmc - Sonoma :: 1996 - Engine Shakes Badly And Struggles To Run / Timing Is Way Off
I have a 1996 GMC Sonoma extended cab, 2.2l engine (not vortec) purchased in the United States. I’m having trouble setting the timing correctly.
I recently replaced the camshaft and crankshaft sprockets and chain, and after several attempts to set the timing, the engine still shakes badly and struggles to run smoothly, especially at idle. (It did not do this before the repair.) My code reader picks up the following codes: P0106, P0108. It seems to me that the timing is off despite my best efforts.
I’m going to try and attach a picture of the timing chain and sprockets as they’re currently set because the camshaft timing mark is strange on this vehicle and I’m not sure if it’s lined up correctly. Does it looks right? (Red mark on cam sprocket made by me; timing mark is supposedly the circular hole above that tooth.)
I did several other repairs at the same time that I did the timing. I have gone back over as much of these as possible and I don’t think I did anything wrong. As cars go I’m strictly an amateur but I work as a small engine mechanic so I have some experience with the way things feel when they’re done wrong. Nevertheless, if the timing is right, maybe I botched one of these?
The simultaneous repairs:
Removed head
Replaced hydraulic lifters
Cleaned carbon off valves
Checked pushrod straightness
Changed gaskets (several)
Replaced oil pressure sensor, coolant temp sensor, & thermostat
Replaced coolant hoses
I did all this because I hit the 150,000-mile mark and I want to keep it running for another 150,000.
Sebring - Chrysler :: 2002 - Shakes Badly Under Acceleration And Braking - Cause?
So. My car shakes badly when I get above 35 mph and up. It shakes under acceleration and braking above these speeds. Under these speeds its fine. When I am above 35 if I am just coasting its fine it doesn't shake. The shaking feels like I am off the side of the road and driving over rumble strips. What could be the cause of this?

I have a 2001 vw Jetta with a manual transmission (just over 155,000 miles). My first set of front brakes lasted to about 135,000. After they were replaced a shimmy started to appear when braking a few thousand miles in. At about 8,000 miles the shimmy became so bad that I brought the car back to the dealer. They said the rotors were warped. The pads and rotors were replaced again and in about 5,000 miles same thing. The pads and rotors were replaced again at no charge and it is now about 5,000 miles later and the same thing is happening again.
View 2 RepliesS-10 :: 1999 Chevy Transmission Downshifting At Highway Speeds When Slightly Let Up On Throttle
My S10 started downshifting at highway speeds when I slightly let up on the throttle. It only starts after driving 20 or 30 miles down the road. (gets hot?) It also hesitates slightly starting from a dead stop as well after that. I dropped the pan, cleaned it up and added new fluid. There was a fine powdery sludge on the magnet in the pan, but no metal shavings. It is still doing the same thing.
It has 95,500 miles on it. 2.2 motor. The fluid was low a couple weeks ago. I added a bottle of conditioner. Don't remember the brand name. 2 reservoirs in the bottle so it mixes as you pour it in. It started acting up 7 days ago.
Silverado :: 98 5.7 Chevy Truck Not Starting
I have a 98 chevy truck that won't start. After it sits. It was starting after cycling the key a few times. But now it won't start. Could it be the pump? I hear it running.
Or could it be the regulator? It was running good after it started. No check engine light, no gas smell, and no rough idle.
Silverado :: Cruise Control On 2002 Chevy Not Working
The cruise control on my 2002 Chevy 1/2 ton Silverado doesn't work. Went to boneyard and bought a module but it didn't fix my issue. Borrowed a multimeter and tested the cruise control module plugin. The only pin that came up with a incorrect reading was the first brake test. It's suppose to have 12 volts with brake pedal up but showed about 30, so I changed the brake light switch. Still no cruise control.
Since I have a high reading on the brake pin, do you think I have a wire issue there or would my problem be in the multi switch wires by the steering wheel?
Silverado :: 1992 Chevy Truck - Module In Distributor Keeps Going Bad
I have a 92 chevy truck with a 350 engine that came out of a 93 chevy my problem is my module in the distributor keeps going bad when i spoke with the previous owner of the motor he told me that he had the same problem and advised me to change the distributor. So I took my distributor out of the original motor and put in but the problem still exist, also I have noticed that I have nearly twice the exhaust coming from the drivers side tail pipe as I do the passengers side.

View 14 RepliesSilverado :: 1994 Chevy - AC Compressor Engages But No Cooling Really At All
The issue I'm having is the A/C. When I got the truck the A/C was completely freezing. Recently however, the compressor was having issues not engaging and I fixed that by simply plugging the cord to the accumulator thing. . Now the compressor engages, but is not cooling really at all. It is an old truck and the compressor is a little worn from what I see maybe 2mm space when not engaged. I checked the levels of freon/coolant with a gauge and the amount is perfectly fine. Plus there seems to be no leaks.
View 1 RepliesSilverado :: 1993 Chevy 2WD - When Accelerating RPMs Go Way Up And Won't Shift
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.
Silverado :: 98 Chevy Truck With 4L60E Has No Second Gear - Shift From 1st Into 3rd
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?
