BMW specifies "lifetime" fluid for all its transmissions and defines lifetime as 100,000 miles. Therefore, it is a good idea to service your fluid every 50,000 miles. If you're unsure of the last service, replace the fluid as soon as possible. Doing so will extend the life of your transmission.
Check the LevelWith the engine warmed up, leave the car idling in park on a level surface. Pull out the dipstick, wipe it clean, replace it slowly, and then pull it back out. Check the fluid level—how high the fluid comes up on the dipstick—against the "full" and "low" or "fill" marks on the dipstick.
ATF Dexron III is the fluid standard for 4-speed BMW automatics (ZF 4HP). This is also the most common ATF you will find at auto parts stores (it's compatible with most GM and Ford auto transmissions).
Low-quality transmission fluid – or driving without transmission fluid altogether – can cause a number of problems such as transmission failure, gear slipping, a hard time shifting, and a few more issues.
When to change transmission fluidThey are synthetic fluids that are much more expensive but can last up to 100,000 miles. With that in mind, it's often recommended by BMW to change the transmission fluid at 50,000 miles and to inspect the transmission filter closely when you do.
BMW 325i Transmission Fluid Change Cost Estimate. Labor costs are estimated between $148 and $187 while parts are priced at $97. This range is based on the number and age of BMW 325i's on the road.
A rule of thumb with many mechanics say it should be done at least every 50,000 miles. However, the manufacturer's maintenance schedule for many transmissions doesn't call for fresh fluid until 100,000 miles – you need to check your owner's manual to see what BMW recommends for your model.
Signs That You Need to Change Your Transmission Fluid
- Puddles under your car.
- Roaring sounds when you accelerate or go around corners.
- Difficulty shifting.
- Engine revving when going around corners.
- A chattering noise when you start driving.
- A slight burning smell.
- Warning light.
If you drive manual, most manufacturers will recommend changing your transmission fluid every 30,000 to 60,000 miles. If you have automatic, you can typically boost that range up to 60,000 to 100,000 miles. There's no harm in changing your fluid early.
The cost of a new BMW transmission could be over $3,500 depending on the vehicle, however, transmission services such as fluid changes and a transmission fluid flush are considerably less costly, in some cases costing less than $150. These services are critical to prolonging the life of your BMW transmission.
The cost to have your fluid changed by a dealer, service center or independent mechanic ranges from $80 to $250. The average cost is around $100 for both automatic and manual transmissions. We recommend getting the filter replaced and pan cleaned every time the fluid is changed.
BMW has eliminated the oil level dipstick from under the hood, replacing it with a sensor in the oil pan (the shaded part in the figure). The sensor should warn you if the oil level inside the oil-pan drops below the safe level.
The transmission holds about 10 liters of fluid; don't expect to get it all out, unless you have access to a flushing machine. Remember that your car may have been serviced before and had parts replaced with different size fasteners used in the replacement.
it's a different grade hydraulic oil. they just want you putting in the normal type of power steering fluid in, our bmw's take the same automatic tranny fluid grade.
It's a sealed transmission. So the only way to check it is to jack up the car, take off the filler plug and sticker a finger inside. You should be able to fill fluid when you stick one finger inside.
The cost of a new BMW X5 transmission could be over $3,500 depending on the vehicle, however, transmission services such as fluid changes and a transmission fluid flush are considerably less expensive, in some cases costing less than $150.
The BMW E70 is the second-generation BMW X5 mid-size luxury crossover SUV. It replaced the BMW X5 (E53) in July 2006. It was manufactured alongside the BMW X6 at BMW's Greer, South Carolina plant in the U.S. and BMW's facility in Toluca, Mexico.
Symptoms of Low Transmission FluidThere are a few easily identifiable symptoms that you may be running low on transmission fluid including: Warning Lights: You will see a dashboard warning light indicating that your transmission fluid temperature is hotter than normal.
Gear Slippage: This is the most common symptom of low transmission fluid. The transmission requires pressure so it can connect the force between the engine and your wheels. This process is critical to make the car run. If the pressure gets too low within the system, the transmission will slip.
No, you can't leak transmission fluid into your engine. They are mechanically connected but there's no way for fluid to get from one to the other.
You can add more by inserting a funnel into the tube the dipstick was withdrawn from and pouring a small amount of automatic transmission fluid into the pipe. Check the level each time you add a little until the level is right between the two lines.
Transmission Trouble: 10 Warning Signs You Need Repair
- Refusal to Switch Gears. If your vehicle refuses or struggles to change gears, you're more than likely facing a problem with your transmission system.
- Burning Smell.
- Neutral Noises.
- Slipping Gears.
- Dragging Clutch.
- Leaking Fluid.
- Check Engine Light.
- Grinding or Shaking.
The manufacturer's maintenance schedule for many automatic transmissions doesn't call for fresh fluid until 100,000 miles or, with some Ford transmissions, even 150,000 miles. A lot of mechanics say that is too long and that it should be done at least every 50,000 miles.
Gurgling. If you're like many drivers, you often forget to check the fluid levels in your vehicle, and if the fluid level in your transmission is too low, you will notice a gurgling noise. This noise is caused by the excess air in your transmission line.
