i have a 99 mustang GT with automatic trani ...it works like a charm but i'm facing a problem that every time i drive the car a lil hard ... for around 10 min .. ex: doing a drift on the corner , turning a hard turn while goig fats or accelerating ... the car just happen to lose power .... much of it power, and the trani doesn't shift properly and if i put in second gear and accelerate a lil it goes to 3k rpm then back to 2 then back to 3k and goes till 5 and when Put on D it always tend to go on the 4th gear and when u accelerates it won't shift to 3 .. u will have to push the gas and in sudden it will shift to 1 or 2 gears .. i don't know what is the problem from .. if i drive my car normally it works very good no problem at all ... i think its a heat related problem but it always shows that the temp is in normal

does any body have any solution for that problem ? is it from heat ? coolant ?
i have just changed teh oil recently but the problem still accrue .

first ... keep your transmission in D
your not pulling or driving in snow... no need to take it out.


second.. you probably need a tune up.

third... turn your TC off :wink

its always on D just telling u what happen if i put it in the second ...
the car shouldn't act like this even with out a tune up
trc has been always off..

[HMUSN]

it's not your transmissions fault.

I'll tell you that much man.

he car act just fine .. till i drive hard for 10 min .. it acts crazy and u feel major power lose and rpm running always low

[HMUSN]

that's because your beating on it and your computer is going crazy trying to control everything and make it stable.

it's called limp mode.

I thought about the computer thing being crazy .. but what is limp mode ?

[HMUSN]

limp mode is also known as safety mode.

it's when your computer retards timing and makes the motor run as safe as it can so the computer can find out the problem with the system.

any idea how to get around this? problem still accure even after turning off then turning on teh engine it only back to normall after i leave the car for sum hour then come back to it

[HMUSN]

don't beat on your car.

then buy a tuner so you can tune your car so it can be beaten on

what is the cheapest 1?

[HMUSN]

the cheapest one is going to be the crappy one that "might" work.

mod correctly man.

HP isn't cheap.


a good tuner is around $380.00

[unblock]

i know, here it costs 400$~ just for a chip tuning .. so for a tune it should be quite more

[HMUSN]

I can get you a tuner for $380 bucks man.

if your in the USA

i'm not from usa
isn't there any 1 in teh forum online? i wanna see sum response from other users :S
sum 1 must had such a problem before .. i can't be the only 1
i still have a feeling its from heat :S cus it comes back to normal after i leave the car to cool for sum hours :s

[HMUSN]

I will step out of your thread now.

You should listen to HMUSN. He knows what he's talking about, and is infact very knowledgable. And I agree. Just buy a Tuner, play it safe, and call it a day, because until you do, that shit is just gonna keep happening.
