4l60e shift to third gear issue
I installed a new stage 2trans because the car wouldn’t shift to third at WOT. Guess what new trans won’t shift to third at WOT either. Car has a 408 and yank 3600.

What is your rear end ratio? If it's too tall, WOT won't allow an upshift into 4th, and I've heard, sometimes 3rd. Slightly lifting will usually allow an upshift. True for you?

Does the engine go to the rev limiter in 3rd and stay there?

Sounds like the trans tune is off. The shift RPM has to be lowered.

Is it revving to 7100 when it "hangs"? If so something is "stuck" in the programming.

So it is basically "ignoring" the set shift point. If it's a new tranny, something in the programming is messed up

Yeah I’m trying to figure out where it could be wrong in the tune, I can attach a file of the tune as well right now for WOT shift MPH it is set to go to 3rd at 90 mph and RPM shift at 6800, but it doesn’t shift and just goes to redline, then I let off and it shifts just fine, I know it’s in the tune just don’t know where I’m the tune.

Yeah, I can't answer that; I'm not "tune savvy".

Ok well a local tuner helped me out. I tried to adjust MPH all over and it didn’t work. He told me to zero out the MPH. It worked. It now shifts to third at WOT.
