Occasional clunk when truck is shifting gears. Not consistent. On highway at high acceleration clunk is more apparent. Any thoughts. 2004 v10 with new engine placed at 70,000km now at 85000km. Otherwise truck is running great.
View 8 RepliesMy 2004 V8 clunks when shifting gears, causing the engine to oscillate right through the seat. It also happens when driving a steady speed, e.g., 10MPH in traffic, and you goose the gas or release the gas altogether. So far:
1. Replaced transmission valve body
2. Replaced stepper motor
3. Replaced rear propellor shaft and bearing
I think this started with a reflash of the trans to cure the death lag.
I Own A 92 Chevy Silverado, 154 K Miles. Runs Great! My Problem? I Experience Rough Shifting At First Take Off, After She Warms Up The Shifting Is Smooth. After Parking And Starting Again, Rough Shifting With A clunking Sound.
View 9 RepliesI just bought a 2003 Camry, 4 cyl (154000 mi.) and the accelerator is a DBW. It feels different than a cable in that it seems to hesitate and after it shifts into second the car accelerates on its own a little bit. This is not a rev up in between shifts, it actually feels like a lurch. It is most noticeable when speeding up slowly. I may be able to get used to it but it doesn't seem right to me. The dealer wants $120 to hook up their computer.
View 1 RepliesI have a 2007 Passat wagon 4 motion V6 and what the problem is I am getting a rough shift between 3-4 gear sometimes, usually on a slow acceleration. I have had the valve body replaced which worked for a couple of months until the problem returned. I then had the transmission replaced which worked a little but the rough shifting is still present at times. The car still has warranty and not even the dealership knows what to do?
View 12 RepliesMy wife and I recently purchased a 2013 Jetta and have noticed some abnormal lag when accelerating. It's an automatic transmission and the gear shifts aren't as smooth as they should be. I have read that it is possibly related to the drive by wire system and may just be an inherent result of that system.
View 4 RepliesToday (not 2 days after taking delivery) I was travelling on the highway. stopped for fuel and as I am decelerating on the offramp when the truck shifted from 5th to 4th it went CLUNK, It did this twice, in the same circumstance. I can't make it replicate the noise every time. But 2 times in 24 hours is enough.
View 10 RepliesI am hearing a noise first thing in the morning when I leave my house and the car is shifting from 2nd to 3rd. The sound, I think, is coming from the front center of car, say directly below the radio area. The noise lasts only 1 to 2 seconds and sounds like when some tries to put a transmission in reverse while still rolling forward. A metal against metal sound of two pieces trying to mate up. I'm thinking transmission...I'm hoping center diff. There was mention of a scraching sound coming from front passenger side on initial startup. Idea was this could be Immobilizer or ABS.
View 2 RepliesI am new to the all wheel drive breed. When I turn the all wheel drive knob one click over to the right (4x4 low I believe) how much rougher should the shifting be. I notice it starts in 2nd gear, but 2-3 shift jolts the car to the point it almost snaps your neck(not WOT just normal accelaration). Each subsequent shift is a little smoother, but still very noticably rough. Is this normal? Even in the regular high mode, sometimes my regular around town low throttle shifts are pretty jolting.
View 4 RepliesSeems like the problems just keep building up. Today leaving work T-reg shifts fine untill it got to 5th gear. It was around 35 mph. Went to give it more gas and it never shifted out of 5th to a lower gear. It did accelerate but even with pedal to the floor it never downshifted. Whats going on. It has done it twice in the past two days. After only having it on the road for less than 5 min each time.
View 6 RepliesI test drove a Skoda Yeti 1.8TSI 4x4 DSG and noticed when driving at full acceleration while shifting through 1 to 2 it goes into the red, past the redline.
Then I decided to test it in my Tiguan 2.0TSI 4Motion 6-speed auto and it went past the redline into the red before it changed.
Now because it happened in 2 vw-group cars with 2 different transmissions it makes me think it is normal.

So today I had a scenario where I had to pull out from a blind corner onto busy street. By the time I pulled out I realized an SUV was coming down the street fairly quickly. My immediate instinct knowing I have 360hp on tap was to put the hammer down.
I basically planted my right foot to the floor and held it there. The truck was already rolling out of the lot and turning into the street at approximately 5-7 mph. This resulted in the truck shifting hard from rolling in 2nd gear, down to 1st. I never drive this way so what I'm asking next is if this is normal or not. As I held my foot to the floor through 2nd & 3rd gears the truck seemed to blip the throttle at 4k then up-shifted from 1st to 2nd gear.
I have a stock Ford Raptor exhaust on my truck with the resonator deleted and when the truck blipped the throttle just prior to the up shift, the exhaust "popped" like a race car with an open exhaust downshifting from speed into an apex. Yes it sounded cool, but it was obviously cutting fuel or throttle for some reason.
So here is the weird part, out of curiosity I tried a few different scenarios just to see if something was wrong with my truck. *Note if I just mash the gas from a dead stop there is no fuel cut going from 1st - 2nd gears at WOT. The fuel cut only happens when I'm leaving out and getting on the gas from a turn.
If I turn off the traction control or advance trac and stability program then there is no fuel cut or 4k rpm, the truck just runs out to the 5600 or so redline seamlessly. Im just wondering if the traction control or torque management is really that sensitive or aggressive? I mean it was 70 degrees out and the road dry, plus I was already at a speed 45-50?? mph where a loss of traction would not be an issue so what gives?
I've noticed on a few occasions (maybe 3 or 4 times total) on my 2005 V8 (about 2.5 months old and 2000 miles) that the brakes seem go into "ABS mode" for no apparent reason. No rain and no snow etc. As I depress the brake normally or even lightly it takes over and reacts like I slammed on the brakes. Then everything returns to normal.

View 5 RepliesI have a 98 Suburban with a 4l60e rebuilt 13 months ago, less than 15000 miles since. I have no second gear at all, but still no apparent slip at all in fourth. R,1,3 are fine. The fluid is a bit dark red, smells normal. There was a bit of the grey paste on the magnet but no obvious trauma. I did find a very small copper wire in there. It's about a 22 gauge, looks like it could have been a 3/8" ring or retainer.
I've replaced the servo, and of course fluid and filter. I pulled off the housing for the 1-2 piston but didn't have the right part to replace. I did not see anything cracked or cocked, it came out and went in fine. The main o ring did look fairly warn, but seemed all-right.
A transmission tester showed second gear being called for on a test drive. I did get a P1870 slippage code a couples weeks ago, I have since cleared it and it has not returned. Could the copper 'ring' be a retainer for something related? I'm guessing the solenoid, but I believe it also applies to 4th gear.
I just recently purchased a 1996 celica GT Hatchback. It had 263K on 235K the timing belt was changed, oil and filter, tire rotation. When I bought the car on the 13 of August it drove and ran well. Drove it home over 45 miles with no issues. Only issue I noticed was that third gear grinded a bit but it's to be expected. Today after it had sat for all that time with the lights on the battery was dead. Jumped the car. cleaned and protected the contacts on the batt. and hooked it all back up. Let it charge for an hour and then drove it to work. On my way to work the engine oil light came on and the car died on my. It has oil and there are no apparent oil leaks. The car is turning over but not starting.
View 8 RepliesWhen my ex shifts from 1st to 2nd I get a clunk. If I let off the gas right when it shifts then it shifts normally. Also if I can get the rpms to 2000 or higher then it shifts fine.
View 13 RepliesWhen shifting gears, mainly in 1st, 2nd, and 3rd while the air conditioner is on I'm experiencing jerking / clunking. When I shift it's not a smooth movement and produces a thump. The only way to really avoid this is by letting the clutch out very very slowly. It only happens when the A/C is turned on. Shifting is perfect when the A/C is off.
View 6 RepliesLately when shifting gears, there's this clunking noise as I let off the clutch. It happens more often than not when I'm in traffic and I upshift without giving any gas on the clutch release. Currently got 13k km on my car.
View 1 RepliesLast summer my 04 SantaFe (140,000 mi, automatic) would feel like it was sticking and bumping when backing out of a parking space, then after shifting into Drive it would jerk and then make a huge thunking noise when applying the gas pedal. However, this would only happen sometimes, not all the time, and was not dependent upon the weather, surface, whether it had just been driven or not, etc. It would just happen when it happened. I brought it to the Hyundai garage and they replaced an axle and sensor. I continued having the same problem, brought it back to the garage and they replaced the viscous coupler.
I continued to experience the same problem after that, brought it back to the garage and they had the car for 10 days. I was told they had to get a mechanic in who was familiar working on 04 Santa Fe's and they determined the axle they replaced was bad, so they put in a new one. Everything ran great until I brought the car in early February for an "off balance ceiling fan" noise when accelerating. I brought the car to the Hyundai garage again and had the transfer case replaced.
Now the "clunking/grinding" is back when moving from R to D!!! So I brought it back to the garage again Monday and they said they cannot find anything wrong, and they are convinced it's just a symptom of the age and mileage of the car. However, it happened again today, but worse than ever before. This time it felt like it might not even move from R to D, and then it continued the grinding and bumping after accelerating and then the car felt "sluggish". I am convinced something is really wrong, although they assured me at the garage that the transmission is good, the axle, sensor and boot are all good etc. What else could it be?
