Archived Transmission popping

[Rdunn]

The following problem is going on with my 04 600 6spd. 4wd truck with only 3000 miles. I drove it on it's first trip after 1 hour at speeds above 55 a popping noise is coming from the trans. It's gets louder the longer you drive it happens between coast and light throttle I've been to the dealer 3 times still has the noise. any ideas what's causing this, please help

just a thought

is that the sound like a clunk and mabey a slight jerk caused by gear lash and or the springs on the friction disk from the forces being reversed on the drive line

In my opinion - 04, about 3k miles, it didn't make the noise before and it's making it now and you've been to the dealer. The complaint should be documented by a service report with diagnosis. If it's not get it in there and have it documented, then letter rip. Ticks me off you try to have them take care of something before it goes bad and they can't "duplicate customer complaint" or some BS like that. Do your best with em - it's DC's dime right now and your pain when the thing locks up or something (hopefully not). Good luck. Keep us posted. Sorry for the negativism - some Customer Service people should just go back to customer service school.

Thanks for the info, popping sounds like a key tapped on a window only louder can hear it the best when you listen by the shifter

without actually hearing it it soulds alot like its just gear lash and it would get worse the more you drive it because the fluid heats up and gets thinner

Rdunn - After the description in your last post, "popping sounds like a key being tapped on a window", I was reminded of a similar sound a std transmission I had a while back made (of course this noise was imediately after I forced it into 1st gear while going too slow for second too fast for first - DUH!) it ended up being a missing tooth on the main cluster. Replacing the trans was cheapest fix, for me.



May I suggest going to the dealer and test driving a new truck to see if it has same noise, or better yet if they have a similar used truck. If the test truck is quiet I'd raise hell to get the trans replaced. Goos luck.
