2005 GTO 4L65E with Yank SS 3600

Well something strange happened last night. While waiting for my friend I got bored so I though I would stall the car up to 2000 RPM's. So did, around 1900 the car jerked/surged alittle... not really like it was giving loose (I stall it up to 2400 at the track) which I thought was strange so I stopped. Well my friend gets in the car and we take off. The car would surge bad, it would go up to 2000 RPM's and then surge down to 1500 RPM's. The car would shift fine it was just surging... not really slipping. It did this till we got home and then again when we tried to drive it 30 mins later.

So then today I take the car out and everything is working just fine as it should. I'm wondering if I got a bad TC? Nothing like this has ever happened and I only have 7400 miles on the car. The 4L65E is a pretty strong tranny, I should at least get 25k miles out of it. If I gotta rebuild it I will, I have the money to do it. I'm going to a FI set up soon though I didn't want to rebuild the tranny till it went out.

The ss yanks are nice peices!Sounds like more of a tune or sensor issue to me if it was a convertor issue it should do it all the time almost what does your tranny temps run?

Not sure how hot the tranny runs.

Though I'm for sure it was not hot. It was running for 7 mins max when it happened, maybe drove 1.5 miles (not running it hard as well).

I kind of agree that maybe it is a tuning issue. The car needs a retune this week anyways, I'll talk to my tuner about it.
