The transmission fluid should be changed along with the fluid filter inside the transmission every 60,000 miles or 175,000 Kilometers. Use ATF type DEXRON VI

With 150k on it I would consider replacing the oil pump and adjusting the valve lifters.

Testimonial: "Thanks for the suggestion. The trans fluid is fine. I didn't know if I needed to go to a transmission repair shop or somewhere else. Sounds like I should try having it tested first."

SOURCE: transmission slipped in second gear

Have the transaxle rebuilt or install a reman

Lucky to get to 100,000 miles,even if you changed the fluid
every 30,000 miles,which now one does

probably not overdrive, most likely the lock up toque converter, most likely a trany. service will cure the problem, but wile you are in the transmission changing the filter you could replace the lock up converter switch just in case it might be going bad, also when you refill the unit put a quart of transX in with the new fluid, its like miracle juice in a can, the best thing i can tell you about the switch is to buy one there not that expensive less the $30 that way when you remove the pan you will know what to look for. i guess the best way to know if its the lock up converter or overdrive is the amount of the RPM change under 400 RPM change its the converter over 400RPM then its 4th gear in either case the first action to take is the transmission service, also there is a 4th gear switch inside the pan as well. if it turns out to be 4th gear dropping out replace that switch also, if the service and switches do not cure the problem then you are looking at a new transmission.

but i am pretty confident that the service will cure it.

let me know if there is any thing else i can do for you.

SOURCE: 1999 Malibu with a 2.4,

Yes, crank sensor may be the problem. Have you looked at the sparks to see if they are strong and periodic? A new sensor is under $20--lucky you. Here is a quick test of the sensor, which is just above the oil filter:

  1. Turn the ignition key OFF .

NOTE Inspect crank sensor and connector for signs of oil leaking through the sensor. This would indicate a defective sensor.
  1. Unplug the sensor electrical harness and check the terminals for corrosion and damage.
  2. Check the sensor wiring harness wires for continuity and repair as necessary.
  3. Disconnect the sensor and connect the test leads across the terminals A and B .
  4. Resistance should be between 900-1200 ohms.

You could try having the fluid changed but beware, if it hasn't been changed in the last 100k miles or so the fresh detergent in the trans fluid can sometimes clean too well and leave you needing a new transmission. If you know it's been over 100k without a fluid change my suggestion would be to keep nursing the trans along and start saving money for a new transmission or a new car.

Transmission slipped when taking off in a 1997 chevy lumina

Consider the following:
Transmission Fluid Level: Is it low? Overfilled? When was last Fluid & Filter Change?
Engine Cooling Properly? The Transmission fluid is cooled inside the Radiator.
Vacuum Line(s) leaking?
I own several 1997 Olds Cutlass Supreme SL's and all have 150k plus miles. Still running strong. If you take care of them, they will take care of you. Worst case is the transmission is in need of repairs. $900 to $1200.

Should you change transmission fluid on a 2002 silverado 2500HD with 6.0 after 150k miles for the first time works fine

The fluid should be changed along with the filter every 60,000 miles, the whole idea is to keep the transmission working well, it is "preventive" maintenance and is essential to keeping the truck running a long long time like new.

Service 100 thousands miles

The 04 was pretty straight forward.

Change the oil and filter when the display tells you to. (Don't forget to reset Oil Life system!)
when the display tells you to change engine oil... Do the following as well:
~Lube Chassis Components
~Check Tires for Air and Damage
~Inspect Break System
~Check Engine Fluids and Washer System
~Check Power Steering System
~Check Wiper Blades
~Check Restraint System
~Lube Body Components (See manual)
~Replace Cabin Air Filter (Located in firewall on passenger side.)

Every 25K miles do the following:
~ Inspect Fuel System, Exhaust System, Accessory Drive Belts for damage or wear.
~ Replace Air Cleaner

Ever 50K Miles
~ If used for Towing - Replace Transfer Case Fluid :: If not change fluid ever 75Kk miles.

Every 100k Miles
~ Change Automatic Transmission Fluid and Filter
~ Change Automatic Transmission Fluid and Filter again at 150k if heavy service
~ Replace Spark Plugs

Every 150k miles
~ Change Engine Coolant (Or every 5 years which ever comes first!)
~ Replace Engine Accessory Drive Belt

optional y are supposed to change the transfer case fluid every 50k if towing
