Trying to diagnose transmission issue

Car is 07SS. Once in a while, when slowing down after acceleration, the car jerks and shutters upon re-accel. Its most prominent going uphill. The issue is very hard to replicate since I removed the tune (superchips). I have about a year left on my powertrain warranty and wanted to try to get the issue looked at, but again I cannot seem to replicate it.

Could this be a component of the transmission that I could replace myself for low cost?

Thanks in advance guys (and gals (G.B.A.))

Triple Edge Performance has some good info on common failure points in the 4T65E transmission. You can check it out here: http://www.tripleedgeperformance.com..._Problems.html

That might give you a good starting point.

How many miles are on the trans?

its usually the torque convertors that fail with the LS4 cars

My Mom's 07' SS has the same issues the tranny slips and slams into gear at take off. I think the trannys were not made to handle the power the engine produces. Every trip to the dealer is just some other exuse about how that is "normal"...

Id prefer to have the issue fixed before I am left stranded on the highway halfway between NJ and VA. I hear a lot of people say they experience the same issue, but have not heard one idea as to what could be causing the problem.

alfredosmith- causing the the problem is bad trannys,from gm..!!.espically on the 2006 cars..daughter 2006 monte carlo ss v8, was sliping/banking into gear like every body said ,and keep getting a little worst daily, she traveled about 150 miless round trip to her job in nj, 5 days a week.. when gm dealer pulled down the pan was all kind of junk in there.. this happened at about 40,000 miles out of warranty for an 2006..we had some dicussions with dealer, and they knew that was a problem, with these trannys ! split the bill with us.. bill was $3,500 for rebuilt gm tranny,we paid $1750 , total !! and also gave her a new loaner car ,while tied up.not a ss or anything, but was wheels...monte has 100,000 miles on and great car never back to dealer since., the tranny still has 40,000 miles on warranty.. of course if its a 2007 all this is free, for the first 100,000 miles..rkvette

My 08 SS is starting to slip a bit as well with 76k miles on it. Dealer said I should just do a tranny flush... I would rather get a new tranny!! Cant see that a tranny flush would help this matter!

i guess if your gm dealer wants to do that n/c ,its ok .. dealer may think with high miles , may/help take care of the problem ? if does not solve it you tried dealer ,solution... about 10 years ago with a company car mopar/chrysler, dealer did that slipped the same and leaked bad.. soon after tranny had to be replaced.. you are luckly have a 2008 impala, covered for 100,000 warranty ! good luck and stick to it, to get the results.. rkvette

Got my rebuild from GM, also changed the front motor mount. Problem has gone away for the most part. I think the slamming into first issue was caused by the motor mount. The other issue was a "burnt #2 clutch" according to the lead tech.
