Thread: Blown Tranny? GTP Cruising @50mph

2002 GTP with 129,000K. It never missed a beat. I gave it fresh fluid 5,000 miles ago, even the old fluid looked new! No rough shifts, no slipping, no clunks, noises ect. I was cruising ~50mph and it was like someone knocked it into N. The rpms went up and nothing. No noise, not a thing. Pulled over and it was like the car was stuck in N, I had no reverse, D, 3, 2, 1. Nothing. I don't get it.

I dropped it off at the local transmission shop. They said they would look at it in the morning. I replaced both CV shafts not that long ago as well. When it happened I pulled over, pushed the ebrake to the floor and put it in D. Turned the front wheels to see if the cv shafts were spinning. Nothing

But thats the weird thing. It wasn't slipping or trying to go at all. It was just like it was in N. I didn't have reverse or any gear for that matter. It's not like it was slipping and trying to go..it's like you took out both front cv shafts.

Oh and if the thing is toast what is a reasonable price to fix it? The KBB trade-in vale is only like $4500 for my car and I still owe like $4500 on it so I'm kinda stuck.


I've replaced so much stuff on this car it's silly. Just got all new tires, all 4 wheel bearings. Brakes, lower control arms, tie rods, sway bar links, u/l intake manifold gaskets, valve cover gaskets, mas air sensor, a few other sensors, ect ect.

Sounds like the input shaft stripped or broke. If the trans shop is rebuilding expect around 2K. http://www.tripleedgeperformance.com..._any_gear.html FYI

Thank you, yeah I saw that link on the website after I made the thread.

Thats crazy if that happened and made no noise! I will find out today what they say.

Input shaft wouldn't be my first thought in this case. Doesn't sound like you are putting down excessive power or beating it.

I'm more inclined towards a gasket blowing out and letting pressure bleed off. Does the trans pump seem to be whining?

Nope no wine at all! The thing never missed a beat, no noises, hard/rough shifts, perfect. Then just like that it was like the car got kicked into N leaving me with nothing, no reverse, D, 3, 2, or 1. When it happened it made no nose I just felt the rev's go up and looked down and was like lol. Then I looked down to make sure it was still in D, it felt like some-one was pranking me and bumped the shifter up to N. I had to have to car towed. Even after it happened I could put the car in any gear and when I would hit the gas it made no abnormal noise, it just reved the engine.

I just got a call back from the transmission shop and he said something is defiantly broken but the only way to tell exactly whats wrong, take it out and tear it apart. Full rebuild $2150 + tax with a warranty on the transmission. Which I think is fair considering the extra work involved with my exhaust. Still a huge bummer though. I've replaced the transmission/clutch in my old 89 mustang but that's a little different than this lol.

I told him go for it because I need it fixed. I'll do double payment to get this car paid off, so much has been replaced I would like to keep it for another 1-2 years before buying a new car. My power levels aren't crazy and I have snow tires on the car so It's not taking any sort of beating. I'm a little bummed to say the least.

Dang I wish I knew that!! I got it back today and the first thing he says was "do you do a lot of neutral drops" haha I was like first of all I would never do that. Second it has snow tires on it...

He said the pump failed resulting in everything going. He said the 4th gear clutch whatever blew to pieces and a few of the other shafts had splines that were ready to strip. He said it was full of metal shavings...when this happened I pulled the dipstick and the fluid looked new? I was like, it didn't make any noise just seemed like I knocked it in N..he said cruising at 50mph you would of never heard it. Also he said the new rebuild came with some hardened 4th gear stuff so it will never happen again for the life of the car. I really hope so!!

I hope I didn't get scammed. Either way this guy and his wife won't have to worry about bills this week. In this economy I'm happy I could provide this guy with work, I just hope it was honest work. Thank you all for taking the time to reply to my frantic questions!

Our transmissions have a few weak things that should be addressed in a rebuild. One is the 4th clutch hub. it's a shaft with splines that aren't hardened from 97-02 and many early 03's that were built in 02.

The splines wear over time and if you accelerate/do a lot of hills where a 4th to 3rd downshift happens it gets much worse quicker. The only piece available is hardened and a typical rebuild includes this part.
