My son has a 2014 CTS with the AISIN TL-80SN 8-speed transmission, and he has been giving me a hard time about the 8-speed transmission having a clunk and being rough and it seems to search. I was down to see him in Florida in September and he was unable to replicate the noise, but his complaints continue, he is unhappy. Supposedly the dealer replaced his transmission but he STILL has the problem, VERY ODD indeed. I searched and found that many had complained about the 8 speed clunking and one member said "the original transmission with the clunk has been decommissioned". I wonder if it is possible for the dealer to have replaced my son's transmission with a tranny that was BEFORE the decommission and the problem persists? Has anyone heard of this? Are there any GM service bulletins? Me being a Cadillac lover, this makes me sick and I have become the lightning rod by my son, because of this. I NEED to get this fixed. My guess is that the dealer replaced this tranny with a unit with the same problem. My son bought the car used, how can I guarantee that his transmission WAS in fact replaced and that they are NOT stringing him along, not that I don't trust GM, but I have seen the dealers do some shady stuff. Is a call to the regional rep the way to go? I loved the car and felt very safe in it in spite of my son driving it aggressively with me in it on Florida 95. Thanks, Mike
Hi all. I have had a clunk in the right front of my Deville for as long as I can remember. I think it had it when I bought the car. Anyway I have given up a few times trying to figure out the cause, and I am starting to pull my hair out because it sounds louder now but I just cant detect the exact problem. Here is what it does. If you hit a bump on the right side only it clunks I cannot feel it in the steering wheel. Drives straight and wheel is straight If you hit a bump(speed bump for example) where both front tires contact, nothing happens It is specific to the corner only. I have replaced inner and outer tie rods. (inner had play when I bought the car) I removed and rebushed the lower control arm last year when I repaired the strut rod portion. I replaced the balljoint when I had the control arm out I replaced the hub assembly (noisy but no play) I replaced the sway bar links And lastly I replaced the whole strut with a donor unit (basically to see if anything would change). Nothing has solved the noise I have jacked it up by the body and checked for play, also inspected the subframe bushings which look surprisingly good for the year and miles I jacked it up by the control arm and checked for play. Nothing. I have tried bouncing the front end, grabbing the wheel and checking while on the ground. Nothing at all. I am down to thinking it can be sway bar bushings(I would think it would be noisy with both sides though) I inspected the swaybar and found no play or cracks Subframe bushings worn. I would not know how to find out if this is the problem. Replacement strut just as bad as old one. An expensive gamble for a new unit. I am baffled that as much noise that it makes that I cannot find the cause. I thought for sure that when I fixed the strut rod bushings last year that that would have cured it, but not with my luck. And another thing that has been driving me nuts. The clock is running faster than usual. It gained 9 minutes in a month. This is very common to these but I dont know why. Usually it will be 10 minutes fast after about 6 months but not lately. Maybe I will have to talk to the dealer on this one. Thanks all in advance for any insight
