and also my rear tires tow in alot does that mean i have to charge the struts the mechanic sais my suspention is tight as a button im not good with suspensions but i know everything else on my G like the back of my hand

let me know if anyone can help

 

How long do you warm up your car before driving? That may be your shifting issue, tranny is cold.

For the rear, post up a pic of how it looks. Is it a huge difference of how it used to be and when did you notice it?

 

2-3 minutes max to long is bad,u get carbon buildup

 

How many miles and has your transmission been regularly maintained.

 

it has 134,000 well maintained throught the life of the car

 

Does the transmission "studder" when going from 2nd to 3rd also?

 

i think so kinda like a hesitation im not sure if its a grind it kinda sounds like a heat shield thats rattling i gotta check it at the dealership.

 

It's hard to tell, but if it's not your tranny it could also be your engine mounts. Probly not though

 

I hear a grinding noise whenever I drive the car after it has sat for a while, going from 1-2, and 2-3 I hear it. I know what the ABS test sounds like, this isn't that. It has started happening the past few months, and I don't notice anything different as far as the performance or driveability of the car, but the sound is a bit worrying. Granted I have almost 100K on a transmission that never had its oil changed.

 

wow! arent you suppose to change the tranmission fluid at like 30k?

 

mine acts the same way no power loss good shifting nice and smooth i lil agressive wen cold and well maintained tranny up to date my car also has 138,000k and ya it still hauls *** again any gt mustang or 5.0's

 

I would drain and replace the fluid every 30k if it were my car.

 

oh i change my tranny fluid every 30k for sure its an expensive machine gotta keep it tip top

 

+1 on letting the car warm up before driving it. I usually start my vehicles 5-10 minutes before i drive them in the winter. You say you change your fluid every 30k? Honestly, when was the last time you changed the fluid. *how long ago? Be honest, like a doctor, you have to tell the truth or how do you expect him to help you

 

i got trany flush 3000k ago like 4-5 months ago
