Go easy on them flushes.
A flush will not flush away your problems.
First tell us your problem.
What transmission and what engine and what mileage?
And or service and repair history??
What is it doing or not doing?
What are your codes?

ok it is a 5.7 engine, with the 4l60e trans. The problems are the trans will not shift into 2nd or 4th. That is the only problem i can really think of with the trans. I started having problems with it when my dad and i were pulling a load home from chicago in overdrive. Once we got off the highway it started with the shifting issues. I doesnt seem to be getting worse but when it is really cold it makes a noise until it shifts, then i will be gone until the next day. I really wanna get this fixed but i dont wanna have to change the trans if i dont have to.

Thanks

Ok than you have reverse 1 and 3 gear right?
No 2 or 4 gear at all?
Any check engine light?
First step is to check transmission and engine pcm or codes on a good capable scanner.
Post back any codes.

would autozone be able to check my check engine light and tell me if it is the trans or what?? i know i have to hook a scanner up to it but if autozone has that or not??

You can try and see But.
Most AZ and other free codes checks places are only good for OBD11 engine checks.
Which may or may not show anything on transmission.
If not You will need to find someone or a good repair shop that has a transmission/engine/body manf. spefic capable scanner.

96 up VCM systems are capable of storing history and present codes.
If light has been on or is on a good scanner will show history or present or pending codes.
What is your service or repair history on the transmission.
Does it no go into 2 or 4 gear or does it just have a problem going into them?
Give us all of the details on up shifting?
Does it have lockup?

[kenkim8283]

well when i start to drive it i have to take it to about 2500 and then let off the gas a little to get it to shift to the next gear. mayeb 2nd but i think it is 3rd. and as far as 4th i feel a little shift when about the 45 mph range. i just think a flush will help it with the shifting bu i am not sure??

What is your mileage?
On a normal take off what is your upshift shift mph.
1-2 2-3 3-4 and lockup?
Also keep in mind that a engine has to be running right for the transmission to work right.

Beware on flushes.
Flushing may not flush your problems away.
In some cases it will flush up more problems.

To Flush or not To Flush ?
Just like Kenney Rodgers said you have got to know when to fold and when to hold. And also when to flush.
If the fluid has high mileage 100K or over or is real dirty you had better hold.
On a trans that has had good regular service at 50K or sooner a flush is good.
But be ware of jiffie/quick/wallmart /fast lubes that offer power and fast flushes.
They have abused and over rated the trans flush.
They have a habit of using one fit all fluid out of the same barrel that fits all.
They just throw in a bottle of additive to make it fit all. Or worse they pitch in a bottle of cleaner or dope in it that can do more harm than good. And will tell you the filter does not need changing with a flush.
Just remember that all new fluid makes a high detergent cleaner that will break loose all varnish and dirt and grit in the trans and drop it in valve body and solenoids.
Always change the filter and go easy on or use no dope and cleaner.
Adjust/check the bands and linkage on the trans that have bands and adjustments.
Always use the trans fluid the trans/manf calls for. And be aware that some manf have changed the type of fluid specs since the trans was manf.
Some fords have changed the specs and a lot of cry/dodge have gone to the newer type of fluid on their trans service.
Also some fords have tsb’s and require a total complete trans flush to cure trans shifting problems. Some as low as 30K
If a person does not have a flush machine a old 5 gallon bucket and a couple of rubber hoses to connect to the cooler lines and with the other end in the bucket will make a good flush machine. Just put the hoses in the bucket and start the engine and start pouring fluid into the trans until the fluid running into the bucket gets good and clean.
It usually takes 16-20 qts. To get a good flush.
Flush or No flush always service the trans filter and trans on a good regular basic.
People that keep the serviced have a lot less trans problems.
