Question about 2003 GMC Yukon Denali

1 Answer

I have a 2002 Danali XL. I am having a transmission issue. When I am using revers, then switch to drive, I am hearing a rather large 'clunk' in the trany. If I don't let it completely catch into drive it makes the noise. I don't think it's the transmission. Once I'm driving the tranny doesn't slip at all. A friend at work said that the drive shaft 'floats' into the transmission and that it probably needs to be pulled out and lubed. Does anyone have feedback? The floating idea actually seems to make sense to me...

That clunking could be the result of a worn transmission mount or work u-joints in your driveshaft. The vehicle will have to be hoisted on a lift and inspected, while someone shifts it from reverse to drive, to pinpoint the noise.

2005 Dodge Grand Caravan 3.3L, hear clunking near right side of vehicle while in drivers seat facing forward. More pronounced over bumps, large or small as if something is not mated properly or...


check the stabilizer bar bushings and the stabilizer bar links. They are very common to wear out and cause clunks over bumps. In an open area and just barely moving turn the wheel to the left and right fast and far enough to get the whole vehicle rocking back and forth. If you hear it under these conditions than it is 99% of the time either the links or the bushings.

2002 FORD F250: I hear & feel a loud clunk occasionally while braking.


I am guessing this is when you have slowed down to just a crawl, mabey 5 - 10MPH or less. If this is the case the clunk you hear/feel is the transmission shifting in to first gear. There may be some issue with a universal joint on the driveshaft that amplifies the situation (have that checked out) If this seems to be the case I would not worry too much other than having the universal joints given a once over.

I hope this may have helped,
Tom

Chevy avalanche transmission problems


Hello;
Are you getting the check engine light? If so the electronics may have gone out. You may not need a rebuild but you won't know till you pull the oil pan on the transmission and inspect the contents. You may also have lost the neutral safety switch. It is mounted on the drivers side of the transmission. Check those out first and let me know what codes you get.
For Ponchoboy; the clunking and hissing you hear are teminal root causes. Drop the oil pan and if it has a lot of filings and metal it is time for a rebuild.
Hope this helps; Rate me highly;
