I'm not sure what my goal is in posting this, maybe just feedback if anyone has any;

I had my transmission fully rebuilt last June. The trans now has 31k (kilometers) (just shy of 20k miles) on it and it feels like the torque converter is shot again. At highway speeds (100km/hr to 120km/hr) I'm getting stumbling/bucking when attempting light acceleration or just maintaining speed.

It not totally consistent at the moment but I expect it to get worse.

So can anyone think of why this would happen? Of course I'm past my warranty on it so I don't think I'm going to have much luck there. Are the transmissions and components like the torque converter on the SSEis really that weak? Or does this sound more like a defective part and/or a bad rebuild?

All I know is that if I get this rebuilt again (likely elsewhere as this place put my boat roller mount on upside down leaving it sticking out the bottom of the car several inches) it had better last for several years or I might as well look for another car.

Any input is appreciated. Even if it's just a theory.

Thank you

This isn't a transmission issue, this is an ignition system issue.

When I first had this problem, new ignition wires solved it. When it came back again a month ago, new coils solved it.

I would replace your plugs and wires to start, then the coils, then the ignition control module. Cleaning the MAF sensor wouldn't hurt either.

If you're right, I would be thrilled. And you can bet I'll be back in here thanking you.

I replaced the coil packs, wires and plugs last year already with top quality parts.

The only thing I haven't replaced is the ICM, which I was suspicious of at the time when a misfire was diagnosed due to my past experience with the ICM in my Camaro, but the new coil packs seemed to solve it.

I'm ordering one right now. <$200 is a lot better than a 4k bill. Might as well give it a shot.

Thanks for the input!

I recommend Amazon, or something similar, where a return wouldn't be too much of a problem.

You didn't use platinum plugs by chance did you?

Went with RockAuto. They're usually pretty good with returns.

No, I used Iridium NGKs to replace the OEs.

So, I got a new ICM, installed it, and it seemed like the problem was solved for about 24hrs.

Now I'm right back where I was before I installed it. Same stumbling, etc.

I feel like there's something wrong with the ignition system but I've literally replaced every component at this point. I'd pull it all apart but it's freezing cold outside with snow everywhere, and my garage is already occupied.

I may just bring it into my mechanic in the near future.

If you have security torx bits, get some MAF cleaner and clean the filament on the MAF. One last quick ditch effort

I just cleaned that sucker last summer, but it's easy enough to do. Not like I have anything to lose.

Thanks, I'll give it a try!

Have you check fuel pressure?
