Why are the rpm shooting to the red when I smash the gas on takeoff?

Asked by Apr 14, 2015 at 10:28 PM about the 2004 Ford Mustang Coupe

Question type: Maintenance & Repair

I like to tend to try and accelerate
really quick sometimes and it has
been not doing what I want it to do. I
used to have a truck and I could just
hold down the gas and it would just
book it and go without any problem
but when I got my mustang it won't
do like how my truck was. I could
stomp the gas on my car and the
rpms with shoot up to around 6 and
then shift and it shifts kinda hard and
then go but I would rather it not do
that. Can somebody tell me how to
fix it?

Your tranny and rearend are not built for high tourque take off,it has what they call a stall converter that keep,s you from tearing the rearend out of the car,it slowly slip,s in to gear,you would have to change or beef up the tranny,and the rearend.
