LS4 Performance - 2700 miles and it is in service for trans issues

yup. at light throttle it slips going into 2nd and has harsh shifts. yey

That sucks paul!!

And the one you leased and beat on gave you no problems.

Go figure...

That sucks, wonder what the problem could be. You'd think at 2700 miles nothing could really be worn out yet. There is a TSB out for the 2nd gear clutch causing slipping/ shuddering at light to moderate throttle, maybe have them look into that.

Well, at 240 mile my trans went nuts. It was shifting rough and the "check engine" liight came on. After a long diagnostic, it turned out to be a frayed wire shorting itself on the outside of the transmission.

Paul,
sorry to hear about your 07... Makes you wonder how the hell your 06 never gave you any problems. Maybe ask the dealership if they still have it and have them replace your trans with the one from your 06? :D

u know what i think. i beat on the blue one from day one. i was aggressive with it. this 2006 i babied like you couldnt believe. only went WOT maybe 3 times in the first 1,000 miles. i would take off from lights very soft. after they fix this. im putting in shift kit, tune, and driving like i drove the other one

since its affecting all gears it's most likely somthing is wrong with the VB. Could be somthing clogging up a passage or a bad piece of electronics. Looks like yours is comming out too..

Or maybe it's a problem with the torque convertor

well they are replacing the 2nd clutch pack i guess. i get it back tomorrow

Sorry Paul on the Trany issues. Did you get your headrest?

I'm in the same boat-- my '07 SS has 9700 miles, and I have taken it in at least four times for tranny issues. In my case it's an issue of a noise and vibration with minor wheel shake that ramps way up at 45 MPH, levels off, then it picks up volume from 90 MPH onward. It is not dyno tune related either, as this was going on before the tune and to me it sounds like a bearing going bad about 6" to the left of the car's centerline. At any rate, the dealer has said it is a tire issue and has tried four wheel alignments on their Fred Flinstone machine ("Thag use rock, make wheel move!!"), inspected the suspension three times, replaced one rim, replaced the intermediate shaft, consulted a ouija board, driven the car at over 100 MPH on the freeway at my behest, and sacrificed a goat to read its entrails all in an effort to isolate the problem. I finally bought a set of 17" OEM rims/tires off of a fellow board member here, had those rebalanced by someone else, and had a 4-wheel alignment done again this time on a Hunter machine JUST SO I can go back to the dealer and say, "Sorry guys, but as I've been saying all along, it's not a tire issue."

Why don't service advisors listen to car guys like us who know WTF they're talking about?? After spending all day listening to dimwits and MILFs in their Suburbans and Tahoes try to ask for a simple oil change ("My husband says I need to have the oil thingee replaced...") you'd think guys like us would be a breath of fresh air to them.

Just call me "Cactus", 'cause I can get miiiiighty prickly. :mad:

I've experienced this shit all to many times. I had my 02 monte carlo in for transmission service 9 times. Thats not counting how many trips it took to convence them there was a problem

well they are replacing the 2nd clutch pack i guess. i get it back tomorrow

It wouldn't burn up for no reason...so I hope they know why it did that and correct it so it doesn't happen again...

If it disintegrated than thats a problem with the pack itself or the fluid....

Thanks for the tech info, Paul. I'm going to use this to get my issues looked at closely. Does this happen ALL the time, or can it be a sporadic issue? I can't replicate it on demand, but it happens nonetheless.

happened like once a day. trans guy couldnt even duplicate it but knew by the way i described it that it was this bulletin

I understand your frustration. I am actually a service advisor at a Chevy/Buick dealership and the other guys I work with know jack shit about cars. You can tell them all you want when you know something because they still wouldn't know what you're talking about. All they know is what the tech tells them and if you don't have a good tech working on it you get screwed.

HMMM the bulletin says "light to moderate" acceleration mine is only at WOT. Otherwise it looks like a match.
