1998 gt squeal when shifting?

I just recently got the car and I've discovered that when hitting the pedal rather hard and acceleration there is a squeal as it shifts gears? Any help with this problem... The cruise control didn't work when I got it either

Stick, auto? If stick does it squeal when you push the clutch pedal in or stop or whatever? If auto have you checked the fluid or done a converter flush/fluid change? Also might be as simple as an old accessory belt that is squealing in the higher RPM range or a failing accessory causing a lot of drag. Need more details.

Its an automatic and the fluid levels are all good. How would I go about flushing the fluid and replacing? Is that something that cost a lot? And the belt looks fine no cracks or visible wear of age or anything. It has mad a squealing once at a stop light while stopped with brake ingaged... that's only happened once though

Best way to flush your trans is too take it to a lube spot or and or car wash places like that its relatively cheap I paid around 50 when I had my 95 stang

Yeah if you want an 18 yr old or a tech who wasn't smart enough to get a real mechanic's job to do your fluid change... eff that... Take your car to your local lube/whatever place at your own risk and have them use "bulk oil" and then not change the filter because they are too lazy.

Put the car on ramps, pop the trans pan, drain all the fluid and then if you have an accesss port for the converter drain that too. If not there is a trick to flush the converter once you get it all buttoned back up.

Also, the belt does not have to be cracked or anything to squeal, it might just be stretched. I'd replace the accessory belt first and see if it still does it. Also make sure your accessories aren't all bound up while the belt is off. You would not be the first person to have a gummed up water pump or alt making the belt squeal.

Most jiffylubes, minekes, etc, etc, hire young kids to work there. How do I know? I'm 18 and have worked there. 80% of the people that worked there didn't really know what they were doing.

To the original poster. If you aren't comfortable doing it yourself, take it to a reputable place.

From what you are saying, you definitely need to flush the transmission. Your transmission is probably on the verge of going out. I flush my transmission on my 04 mustang every 30,000 miles. If you have never flushed the transmission on an automatic and have over 90,000 on the car, you are damaging your transmission. Flush immediately...

Some stereotypes exist for a good reason. And by trans flush I mean a full FLUSH (not a drain/fill) till it runs clean so yeah... you are getting all the fluid.

Oh and the sound comes from under the hood I don't really think its transmission related.

Squealing from under the hood is usually the belts, or the belts rubbing on a pully that is not rotating efficiently.

So I should replace the belt and possibly replace pulleys? Or is that jumping ahead and wasting money?

When you shift and your car engages to the next gear, the engine that drives the belt has a jump increase which of course pulls the pullys. The cheapest way to solve the problem is to check your belts. If they are cracked or even if they appear to be worn down (Melted look) without the cracks, this is a sign your pullys are bad. If they are fine, most likely the belt isn't tight enough and when the engine goes the engage after shifting, the pully is rotating faster than the belt can pick up and makes a sqealing sound.

So, pull/rotate the belt around the pully's without the car on. If you can move everything with ease, the belt is loose. If with some force, you can get the belt and pullys to move, then lube the pullys with somethick grease at the bearings.

These two things should do the trick.

Also to help eliviate some tension the engine has which also increases gas mileage, you should think of doing a basic upgrade and add an under engine pully to your car. Parts and labor should run you no more than $375 if having a mechanic do it. This will add another larger pully to the underside of the engine block and a longer belt. It will overall reduce the amount of effort your engine uses to take off as well as reduce gas consumption since your engine won't be working so hard.

Thanks! That's a lot of great advice and very well explained! I appriciate the help ill try that later and most likely get the bigger pulley installed but where would I have to go to get that done?
