Pontiac GTO 2004-2006 - Need diagnosis.. Trans or torque converter problem.

So today i had the gto out and ended up getting on it around somebody pretty hard. The car hit the rev limiter going into 3rd and i let off. I thought nothing of it because it has done that in the past. Shortly after i come up to a stop sign and went on my way. As i start going through the gears i notice the tranny feels like its slipping (more than usual it has a 3400 ptc converter). I was able to put the car home and i checked the trans fluid. The fluid level was fine, nice and red in color still but it does smell pretty burnt. Im assuming it was mainly from driving it home slipping like crazy. It slips bad in reverse, and in all 4 gears. Before this happened the car showed no signs of the trans going out. It also had a rebuilt tranny @ 67k and the car currently has just under 75k. Im leaning towards the converter as the problem because when the tranny went out before it was just the 3rd and 4th gear bands. This time i have nothing. Does anyone have any suggestions?

Sounds like mine....3 times. Converter clutch goes out sending peices into the front pump, front pump goes out and no fluid to the tranny.
Hope this isn't what happened to you, try changing your filter and fluid. If that doesn't help its time for a rebuild and front pump....$300 just for the pump, plus price of a new converter :(

Wow i sure hope not.. Makes you feel like building power in these things is pointless with such a weak tranny.

I know...and I had all the good parts in mine too.

Best advice I centre give is spend a lot of money on a GREAT converter like Yank

I am on my 3rd transmission since 2004. My first replacement was a rebuild and a 3000K PTC was installed. That only lasted a year and then I spent some money and bought a brand new RPM Level IV tranny with a Vig 3000k stall. Now when my car was stock and the brand new tranny was installed, it felt like night and day compared to the rebuild and PTC stall. If I must say, the PTC felt like crap compared to the VIG. If your going to keep the car, spend the coin, get a great tranny and a good stall and tune it right. You will be happy with the results and with your cam, you will really feel like you added 50 hp. Also, I highly recommend a trans-cooler also. They are inexpensive and just give you better protection. We know heat is the enemy to a transmission. Good luck.

If you have over 500 rwhp you need an RPM trannie, they have a program to refresh, for a fraction of the original price so you can play and afore it, level 6 includes the billet output shaft wish is a good insurance after above stated power level ...

Take it to the best. That's Rossler over by Youngstown. But you probably already know that. I've run their Terminator 2 for 4 years without issue at my power. Right now I'm having it refreshed and upgraded to a Terminator 3 for my 427.

Got the call from the trans shop just a little bit ago and he said the converter spit and took the trans with it. He quoted me at $950 to rebuild the trans. What do you guys think?:bang:
If they are using good parts I would say thats a decent price.
Russ, I hope my T3 lasts a long time.
