I never said anything about a dealer telling me that. The dealers dont know their *** from a hole in the ground. There was another post about this in this forum. A guy had his 02 T56 rebuilt 7 times by the dealer, 7 times in 7,000 miles. Give me a f*cking break that is insane. He had a race shop that has done many t56's take it apart and they found this probelem. What measuring tools they used i have no idea, ask them.

If you think about it, it makes perfect sense, new parts (synchros, gears, forks ect) keep getting put in these transmissions and they keep blowing these parts up. DUHHHHHHH obviously its not the internal stuff!!! <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

And people keep saying "well its been made since 98...." THAT DOESNT MATTER. If they have a tooling/machining probelem or whatever that goes unnoticed for a period of time, that has nothing to do with how they were made before. Maybe they tried a new process and within the last year at the plant? who knows. All I am saying is that an out-of-spec casing seems like a very very logical explanation.

The only thing that will tell if a new trans fixes the probelem would be to get a new trans. I bought a brand new car and i want the ***** fuka to work properly. 1-3k miles per trans is BS.

I am dumbfounded at the fact that some of you are not fully aware how crappy the LS1 T56 has proven to be.

It is nothing new, guys.

Its obvious the "tremecs" arent holding up as well as the LT1 counterpart "borg warner" units. But, there was not a rash of people breaking their 98-00 T56's, with probelems like

- 3-4 shift forks
- 3rd gear synchros
- getting stuck in 4th
- wont go into 1st sometimes

those probelems listed above are showing up alot in the 01-02 cars, i mean alot. There is something wrong with the 6 speeds from the last year and a half, that is what i am getting at.

Not as many problems as the LT1 trans? Well maybe more HP in the LS1. Its just not strong enough.

I just had my 02 replaced under warrenty. It was the 3rd time it has been out of the car in 5500 Mi. It was my trans that the machining was off on. It's NOT dealer crap as the guy who rebuilt it before replacement is;

1 - A mechanic on a race team that has used this trans
2 - Has built a multitude of them
3 - Tracked down the problem with the tech assistance of Tremec themselves

There is an issue with something other than internals as they were all replaced 3 times. It's not shifting tech as I was very easy on the trans and the amount of press used during shifting. My tranny has NEVER been powershifted. During the attempt at the last rebuild he showed me the internals and there was stress placed on the parts with no show of wear at all.

Take it for what it's worth but there is a manufacturing defect with thes trany's from Tremec.

I'll agree about our cars having problems with the tranny/clutches and not to forget the rear-end issues also.

However, powershifting is a known way to break a transmission even if you are doing it right. My 88' TA has the World Class T5 that Irebuilt with Motive Gear parts when I put the 300hp 350 in the car and has never once gave me a problem in the 5-6 years it has been behind the 300hp 350 and I speed shifted it at least 1-2 times every couple days. I powershifted it twice in its life and thats it and took it to the track once. Either the tranny is much stronger or the way I drive it kept it from going out...including the synchros. I'm thinking the clutch and shifter stops are our big problems.

If the car is under warranty get it fixed somewhere else and have GM pay for it. If they say no call BBB and go through that crap and get them realizing that you are seriously tired of the crap and they need to do something different b/c the factory rebuilds aren't fixing the problem. There is a process that you can go through to get GM to pay for the repairs and I believe is similar steps to going through the lemon law process, but instead you keep the car. After 3 times I wouldn't even fool with the dealer again but take more drastic measures.

Knock on wood also but mine has 5500 miles on it with no problems other than my rear-end whine nightmare I went through.

It shouldnt be surprising that the quality of trans took a turn for the worse ever since they started building them in mexico. Also, there can be differences in manufacturing. Tooling wears out and needs to be replaced. Maybe the specs and tolerances got lost along the way.

I'll be taking mine in for the 2nd time. I currently have exactly 5500mi on the car right now. What I want to find out is, has tremec corrected the probelem since, so that if I get a brand new trans (completely new) how am I to know that the casing doenst have the same defect.

hmmm we'll see.

I'm on the equivalent of about my 5th tranny.

I've been crying since day one that 98+ Fbody 6spd's are SH|T compared to the 6spd's in the LT1's.

I've driven MANY LT1's. . . all of them shifted like butter!

In any case, they tried to rebuild mine ~3 times by 30k miles. . . FINALLY the dealer asked for a new one. . .

All felt fine on the drive home, then it popped out of 3rd. I called the dealer and had him check it out. . .

They replaced the tranny w/ a new one.

I have 40k miles on this one. Still feels like **** compared to LT1 trannies. Heck, my friend has a rebuilt one w/ the "Road racing" option from a popular T-56 rebuilder, and that feels like **** compared to the Stock tranny LT1's I've driven.

I've hopped in 98's & 99's on dealer lots w/ low miles & they felt like ****.

I've met MFBA members w/ new SS's & Firehawks and I drove or felt them , and they sucked.

Yout tremec T56's are made in Mexico. Been that way since late '97. The LT1 T56's took MAJOR abuse without problems.

OK I jinxed myself earlier in this post <img border="0" title="" alt="[Embarrassed]" src="gr_emb.gif" /> My third gear blew a month ago.It was grinding into 3rd all year so it finally went.I took the tranny apart myself and replaced 3rd/4th gear syncro,3rd gear and installed a steel third gear shift fork.(Before I was running synthetic tranny fluid) Installed back into car,filled with Castrol reg.tranny fluid.The car shifts better than it ever did.Every gear is silky smooth now.I've been powershifting the hell out of it since without one grind <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> It cost me $400 in parts(www.ddperformance.com) and I'm glad I did it.
