How to change Transmission Fluid

Changing Automatic Transmission Fluid.
For most cars, the Maintenance Tune Ups are scheduled at 30K, 60K, 90K and so on. Most of the dealers recommend to change the Transmission Oil and transmission oil filter at 60K. The transmission Oil can't last forever, so it is a good idea to take care for the transmission before something bad happens, and at 30K the transmission oil start breaking down. So you buy a transmission filter kit and start the job. Lift and secure your car. Loose and put pan bolts in a small cup with kerosene or WD-40. With finesse loose the transmission oil pan. Collect and disposal properly the used transmission oil. The amount could be 4 to 5 quarts. This is only the half. The rest is still inside the car. For now disregard the rest of the transmission oil. Focus on the oil pan. You have to clean inside and outside and check the magnet and residue. A black dust is normal. Replace the transmission filter. Just pull it out and snap in the new one. Don't forget that "O" ring sealer is in place. Clean out the surface of transmission block in contact with the pan. It is aluminum and don't tolerate even a scratch. A razor blade in right angle can do the job. Clean with lacquer thinner both surfaces in contact and the bolts. Dry out thoroughly. IF the oil pan is designed for a gasket, you are very lucky. Apply a thin layer of sealing agent, over the transmission oil pan edge, and position the gasket over it. Mount the pan on the transmission surface and torque the bolts at around 170 in- lbs. If the oil pan doesn't accept a gasket, Chrysler like this,than you are in trouble. You have to wait till the transmission oil drip stops.You need to wait overnight, till 24 hours. Clean everything thoroughly with lacquer thinner. Apply RTV around all holes and, create a gasket with sealer.Too much or too little means trouble. Mounting the pan you have to be very precise, one wrong move and you start again from the scratch. If there are big electrical harness obstacles, ask for a person to help. This happen to Chrysler Town & Country. Tight up the bolts with an extension only. Wait at least one hour and tight up to 150 in - lbs, or (12 ft - lbs). Wait at least 24 hours to cure, before filling up with transmission oil.You think are done. Not yet. You have a new filter, clean transmission oil pan, including the magnet, which must be cleaned and put back in place, but half of the transmission fluid is still old and dirty.
You have two options.
Fill out the transmission with new fluid, disconnect the return oil line at the transmission, or cooler, and collect 4 to 6 gallons and disposal the fluid properly. To do so you need to start engine and move the selector to reverse, neutral, drive and back to park. Connect the line and fill out the transmission with new fluid.
Option two.
Buy 6 to 8 feet vinyl clear house. Insert the house in the dip stick opening up to the bottom, and siphon the oil from transmission to a container positioned on the ground.
You need up to 24 hours to drain the oil. You have to repeat this procedure one more time after a month or so. You have to buy 10 quarts of transmission oil, but this is worth compared with a transmission repair. Keep in mind to buy the specific transmission oil for your car. Check the fluid level with the engine running and add as needed. Check after a week. If level is to high then siphon small amounts and fill up to the mark.

I have 86,000 miles on my 1993 240 Classic. What is the maintenance schedule and what should be done at this time?

Most car dealers recommend maintenance services at 30K, 60K, 90K and so on. The 30K service is mainly focused in inspection of the systems and replace of the fuel filter.
The 60K is expensive for cars with timing belt. The coolant, transmission oil and filter, and the brake fluid has to be changed. The air filter and spark plugs has to be replaced at this time too.
Most costly is the replacement of the timing belt. Volvo recommends for Volvo 240, changing the timing belt every 50,000 miles. Needless to say, they are pretty religious about this now.
The B20, B21, B23, and B230 engines are non-interference engines, meaning that the camshaft can be rotated independently of the crankshaft and no damage will result to the engine. That is, if the timing belt breaks, the valves will not hit the pistons; the engine will simply stop.
On the other hand, the B234 16-valve engines and any of the other Volvo multi valve engines are interference engines. Loss of the timing belt in these engines will result in severe or fatal engine damage.

how many miles for a tune up 2005 chevy trailblazer

Most of the car dealers recommend to perform Maintenance services scheduled at 30K, 50K, 90K and so on.
At 30K they mostly inspect all the systems, and replace fuel filter.
At 60K they inspect systems and flush must of the fluids, transmission oil and filter, coolant, brake fluid, differential and transfer case fluid, and replace the air filter. Some replace the spark plus at 60K some at 100K.
At 90K all timing belts are replaced, and the status of the timing chain checked. A deviation of more than 5 degree means, there it is the time ayes on the timing chain.
At the Owners manual for 2005 Chevrolet Trailblazer recommend:
Inspect all the systems at 25K, and replace fuel filter.
Replace engine air cleaner filter, automatic transmission fluid, automatic transfer case fluid every 50K.
Replace spark plugs every 100K.
Maintenance Services for your car are scheduled at 25K, 50K, 75K,100K and so on. All are tune ups but they are not the same.
The only concern for GM is the GM Dex-Cool antifreeze. There are some complaints regarding this product. I recommend to flush the cooling system every 50K to 60K.

How often should engine coolant be changed on a 1989 Olds Cutlass Ciera?

For most of the cars the Scheduled Maintenance Services has to be done at 30K, 60K and 90K. At the second Service at 60K dealers recomend the coolant system to be flushed. The inhibitors in the coolant starts breaking down, and the result might be a corroded radiator, heating core, and a partially clodgged heating core.
The transmission oil can't last for ever too. It starts breaking down at 30K and has to be changed at 60K.
It is a good idea to flush the braking system with fresh brake fluid too. The 60K service is expensive and it is a good idea to be done by yourself. It is not going to hurt your car if you change the rear differential oil too.

The RPM's fluctuate after the car warms up. I think I need a tune-up.

The maintenance tune ups, for most of the cars, are scheduled at 30K, 60K , 90K miles. If you are late on the scheduled maintenance tune up, of course your car needs it, but to find the problem you need a "Check and Advice", only at Volvo dealer. It cost $65 to $100, on the top of tune up cost.

does it require tune up

Regular Maintenance is vital to keeping your car on the road. The time and effort you put into keeping up with scheduled maintenance can save you big money in the long run.
Dealer 30k, 60k or 90k mile tune-ups can run from $250 for 3-4 hours of labor and basic maintenance, to over $1,000 at places with high labor costs and additional maintenance services, such as timing belt replacement.
If the mechanic identifies needed repairs, this can add a significant amount to your total.
At 90K repair shops normally replace the timing belt, or timing chain.
Your car require a tune up, if you have more than 30K on it. What kind of tune up your car needs depend on how many miles do you have on your car.
