^Can you describe what you were doing and the exact situation where the trans didn't shift as it should have?

I can tell you that in rare instances (less than a handful of times since I've owned my '06 350) that in full AUTO mode I have managed to somehow reach the rev limiter in-between shifts; BUT, the trans DID shift by itself...unlike what like you mentioned.

Happens to me since I put my headers on. But it's never consistent. It could be the trans not shifting quick enough. Or the ecu not picking up fast enough to tell the tranny to change. Mine will hit 6500 and the rev limiter will kick in two or the times then it will shift automatically. Just my thought. But the Tranny might need some maintenance im almost at 100k on mine.

Say I am doing a 40mph roll in 2nd gear with the extra power button off and I go full throttle after I hit full throttel I put it in regular drive right away so the control moduel does the shifting for me. When it should shift to the next gear and I dont let out of the throttel just a little it will hit the rev limiter I don't want to stay in it when I'm spraying to find out if it will shift without letting off. If I'm not spraying it shifts fine with no hesitation.

Yea i wouldn't spray through the limiter unless you have a fail safe for when it hits the limiter. But even then its risky. Your driving it right but what about when you stop spraying at like 6200 6300 rpm keep your foot down through 6500 will it shift?

I've had a few instances when I bounce off the limiter on the unit but it shifts after a couple bounces. Like mentioned above, its very inconsistent, I've only had it happen a few times. I definitely think its the ECU not being able to send the "shift" signal to the trans fast enough.

I don't have any kind of RPM window switch so I don't know. I am going to order one and see what it does for me. hopefully it will work.

also are yall running any higher octane gas to run a 100hp shot?

My transmission does the same thing. Flushing out the fluid didnt help and it is at the correct level. The 6 speed is not fast enough to shift modified is350s. There has to be a reason beside fuel mileage that they use a 8 speed in the f sports.

No Unfortunately, I sold my baby and picked up a 2014 CT200h F sport. We'll see if the hybrid can handle a bit of nitrous lol

My dad and I have actually discussed installing the Unit on his IS350 for kicks, so once I do that ill post some times and install picks
