My transmission/ transaxle has been rebuilt 3 times. What I have researched at this time is that the base model 4t65e transaxle doesn't really differ in the hard parts for the 4t65e-hd thats in my pontiac grand prix gxp. Bad jerking and slipping from take off or accelerating is my problem. Just this year my car couldn't accelerate over 40mph because of this problem. Anyone I talk to who has the same motor combination of the ls4 motor with the 4t65e-hd tranaxle has been dealing with the same similar issues. Wether it be the impala ss 2006-2009, monte carlo ss 2006-2007, buick lacrosse super 2008-2009, or the pontiac grand prix gxp 2005-2008. The front wheel drive combination with the power in the 303 hp motor is too much for the 4t65e-hp transmission. I've found a website that claims they have solved the flaws with this problem. The website explains in detail what parts they use and how it can support the power of the ls4 motor. Personally I feel like I should not pay for something that should've been a recall close to a decade ago.

Steering: clicking noise when turning transmission has a light slip into 1st and sometimes hard shift into 2nd had this looked at in 2013 while it was still under warranty and the dealer didn't want to acknowledge there was a problem. This should be under recall since more people have this same problem.

On more than one occasion, my car hesitated after stopping at an red light. Upon take off while other cars are behind me if feels like my car gears are stuck . I initially thought perhaps it was the weather or maybe my brakes . No, not the problem because my brakes have been checked and the weather is not always a culprit, I even have new tires . The problem is very scary when your grandchildren are buckle up in the back seat and your car hesitate, transmission slipping not changing gears. This has happened far to many times for my comfort and safety of myself and my family. Additionally, there also been times when the fan stop during this time. Both in the summer with the air blowing and just today (11/12/14), with the heat blowing everything stopped intermittently, what is going on with this car! The problem has only gotten increasingly worst.

Soon after purchase, transmission slips gears coming out of a stop. August 2013, transmission dropped out, driving 30mph. Car was not drivable; no gears. Transmission was replaced. Now one year later, slips gears at 40mph. Headlights went out while driving in the dark. Use of turn signals causes high beams to activate. The cabin fan (A/C and heat) never shuts off. Heat works intermittently. Car seems to shake at times. Feels like a flat tire but when checked, tires are fine. Car rolls when in park, even on flat surface. Car rolls back when in drive, even on slight inclines. Never certain of brakes; at times, works as normal, other times, pedal must be pushed close to the floor to activate brakes.

The initial issue that I noticed was when I was driving at 70mph at about 2000 rpms the rpms would jump up about 300 rpms when I would drive at a steady speed, just flat ground. It got worse and more frequent as a month went on, so I then brought to a gm dealership and they decided to do a transmission service (fluid and filter) and inspect what they could, everything "looked good". Now since then this issue has been resolved but the transmission slips and slams into gear, when I am in stop and go traffic or hitting a lot of stop lights, engine temp. Does seem to get a little high, even my mechanic thought so. When it slips it feels as if I hit a giant pothole and the engine/transmission is going to fall out. But this problem is so intermittent no one can pin point the problem, I have had three different mechanics look at this issue and one transmission shop. I have all of this and can't seem to resolve the issue, and not to forget to mention since I have owned the car since 2006, it has never shifted smoothly from first to second gear (when I accelerate from a stop light/sign). I like gm, but when this issue is all over the internet and gm hasn't done anything about it, I am starting to second guess my decision on vehicle manufacture.

My mechanic insisted that I needed to change my transmission fluid in order to keep the transmission running efficiently. I believed him and had it done. From that time, my transmission has been slipping from 1st to second gear. Then I was told my car could use a tune up and that would correct the problem? Had a tune up in january 2014. The trans does not slip all the time, but when I am in traffic (stop and go) it will slip slightly. I take good care of my vehicles keeping up with the maintenance. I see other complaints very similar to mine and feel that general motors needs to be responsible for this problem with the transmissions. Now, what does it take to get a response on this situation? The way I feel now is that I will never own a general motors vehicle if there is no resolution to this problem.
