During heavy braking does the trans go to neutral?
I did a few fast WOT runs, checking for KR, also practicing emergency driving procedures with my handicap
Well after EXTREMELY heavy braking the gas pedal does nothing in drive. it acts as if its in neutral. Is this an electronic restriction in the 4t60ehd?
Its pretty fast that it comes back, remember I drive with 2 feet since I cant move my right foot or bend my right knee. I know if I hit the brakes hard and wait about 1.5 seconds its fine, but we are talking RIGHT after it comes to a stop it acts as if its in neutral,even if i hold the pedal to 2000rpms, its still in neutral, let go and its back in gear.
it only happens during a COMPLETE stop, not when I slow down.
whisky tango foxtrot.

everytime the ABS were on 100% of the time on dry pavement from 100mph+, if that gives you an idea of how hard I hit the brake pedal.

My gas does little when I hit the brakes hard too, but I'm talking about hitting the brakes at say 60mph hard, then immediately accelerating after. It hesitates for a second then finally picks up again. I notice this a lot since I usually hit my brakes hard if someone'* on my ***, then punch the gas afterwards.

wow. i wonder if the trans is trying to protect the car or if the trans has issues lol. Hard to say.
My trans has been on its way out since the day it was rebuilt, (terrible place did the rebuild)....I was not sure if the 4th/0d to 1st gear had happened to fast for the trans to react and put the car back in 1st gear.
the ceramic brakes stop this car SO good its amazing. I dont see how people can talk so much crap about the brakes on these cars, granted the rear is adjusted as well. I think I did warp the rotors just a tad though

I think you're sloshing the fluid away from the pickup (filter), thus starving the pump. Overfill the trans just a LITTLE, and I bet it would go away.

If you were coasting the trans could freewheel a bit... But not when you come to a stop... You should move as soon as the RPM'* come up... I think this trans needs to be looked at... And it almost does sound like a crappy rebuild
Hans have you checked the fluid recently? Make sure its not low... If it is you could experience a neautral of sorts...

Most modern EFI engines cut fuel when braking. This is done to save gas, and it'* almost seamless. Anyone with an aftermarket exhaust, will notice how it'* very quiet under braking.
