Default There it goes!!!

Was sitting in some bad traffic while going to work today and lost my trans. When I was idling in drive, it kind of felt like it shifted, but when I accelerated, it was like neutral, along with every other gear. I didn't think it would happen this soon, its been acting up, but not this much. Our trans guy is gonna pull it this week hopefully, he just had his tonsels removed so it could even be another week. Unless major parts are broke, it looks like its gonna be 1300 for a new converter and complete trans refresh/rebuild. I don't know what I would do if I didn't have cash saved up, luckily tax season is here to help! I would love to make this thing bullet proof, but I am going to settle for a refresh and buy something to toy with. I don't think its worth it to sink a crap load of money into a car that's a dd, and that's not payer off, lol. It's fun, but I need it to last for a long time.

Don't skimp. spend it even if you have to borrow it. that would be stupid to have the trans freshened up if you want it built stout. removal and reinstall is the $$$$ what's it going to cost an extra couple hundred?

No , warranty is long gone Mel. I am at 106k on miles, lol, bought it with 90k. I never even seen a warranty. Tony, I don't know what I really want to do yet, I like drag racing here and there, but I don't know how much it really needs to last. Once the guy tears it apart we will figure it out. Definitely going to have him install a trans cooler. He builds some of the best drag racing trannies in the state, so he will know what it needs.

I'm sorry to hear this, man.

Whatever you do, DO NOT get a GM remanufactured transmission. Contact Dave @ TEP and see what you can do to make the one you've got stronger.

Even if you don't buy from him, he can advise on what you can do to prevent this from happening again without breaking the bank.

Alright, I will probably do that then. Thanks. I definitely wasn't going the GM route. When I got the car, we thought it already had a raman. tranny, because it looked brand new compared to the rest of the engine bay. So apparently, unless it was stock, they did a horrible job.

go into the trans section and post a topic about beefing your trans up i am sure Vince or Chuck from FLT will post, they are great guys and helped me in the past with my TBSS. That should be your next move. DON'T JUST TAKE THE TRANS GUY'S WORD FOR WHAT HE "THINKS" IT NEEDS. know what you're asking for that's why i think posting where Chck or vince can find it is a must for you.

Sorry to hear that. But jus thought it was funny when you said you didn't think it would happen so soon and you got 106K although you only got like 20K outta her. The previous owner must have beat the life outta it. And still that's 3 to 4 times what some of us got.

Lol, it wasn't that it was necessarily so soon. But it only just started having small problems, for the last several weeks, nothing major and it wasn't getting worse. Then all of a sudden bam, no warning sign at all, i went to accelerate and nothing was there.

Also, I don't believe the car has the stock trans, even though I have no paperwork, I believe it is a reman. My gm certified uncle said he thinks that because most remans are painted to look brand new, so when I got the car, it looked brand new where as the rest of the vehicle didnt. But we can't be sure. I highly doubt the car got 106k out of the stock trans.

I just pick up an '06 GXP last week (has high miles 120K) car is mint & runs real strong, I was having fun burning the tires up,... up until the trans let go on Friday, (did not even get to drive a full tank of fuel) , I dropped it off at a local transmission shop this morning, & the owner told me he has already rebuilt the tranny in my GXP about a year ago! lucky I got a good deal on this thing, but I wish I would have researched this topic a bit more, or I would have passed on the deal! oh well **** happens , he mentioned to me there are some updated parts available (drum)? not sure what he was reffering to

Drum usually isn't the issue on a stock LS4. As has been described on many threads here, it's usually the torque converter clutch that fails, and the resulting debris winds up circulating through the transmission, which causes the rest of the trans to fail. I have a thread that describes what happens and how to prevent it in the future. Since you need a whole transmission, I would suggest looking into a few upgrades that prevent it from happening again.

Here's the thread that describes some cause-and-effect of our trans problems, and how to combat it: https://ls1tech.com/forums/ls4-front...e-project.html

It's important to deal with a trans shop that knows how to improve these trannies. Many reputable shops might rebuild our 4T65-HDs perfectly and to factory specs, but since the design and engineering are compromised, a stock rebuild is still a ticking time-bomb.

I recommend you contact a specialist in our trannies like Dave @ Triple Edge Peformance, or one of the shops mentioned above. If anything, you can learn what parts to get and what work needs to be done by your local shop so that you get a reliable rebuild.
