gears not engaging after brake-torque start
gears not engaging after brake-torque start
hi,
i've experienced this couple of times already,
i have '05 5AT and in manual mode with VDC off.. i hold my brake and step on gas.. rev to around 3k and release the brake..
after the brake is released, i floored it to burn some tires..
but after that, i could not shift up.. even when i switch back to auto mode, the car is not in any gears (i think the car goes to a safe mode and it is just in neutral)... i have to come to a complete stop before things go back to normal..
any other 5AT owners experienced this? wut is happening?
thanks,

Could this be a "lock out" feature / effect that happens when the engine is torque-ing so much that it makes it difficult for the transmission to switch gears? I could be way off.
When I had the Evo it was really hard to get into second when quick shifting above 7,000 rpm... and after doing research I was told motor mounts and a new set of shifter bushing would eliminate the play that caused it. I am not sure if this would apply to the automatic also.
Pre-loading a car shouldn't do any damage to the car or the trasmission... it is the burning rubber and high rpm shifts that can cause some down the road issues.

Its probably being thrown into a sort of a safe mode. When you brake torque a car you are putting the a lot of stress on the torque converter. Most automatic transmissions include some safe guards with-in the torque conversion system to prevent too much stress from going into the core transmission.
In general the tires will spin before major damage is caused to the transmission. But why burn up $200 tires?
I've known a guy with an automatic mustang who put racing slicks on and then brake torqued it all to hell and blew his torque converter, so he then bought a performance torque converter and then he blew the rest of his transmission. Smart guy

Doesn't quite sound like you know what you're doing.
I'm guessing age range...16-20 on this one.
