X5 2002 5L40E Transmission Diagram

[pinkmagicgirl]

The 5L40E is a very common transmission found in many cars.
Your inline 6 engine is designed to last 300k miles but your transmission is designed for 80 to 130k. Unfortunately BMW should have used a Mercedes Benz 722.X Transmissions which is far more reliable.



The BMW Dealers are diabolical. They tell you that your Transmission is Lifetime and does not need maintenance. They tell you the fluids never needs changing. They want your car to break so that they can charge you $7,000 for a Re-manufactured or Rebuild transmission or buy a new car.



The only thing you have to know... The Transmission fluids must be changed every 60k and can be done at some, but not all Jiffy Lube station.
It's Common Sense that metal friction moving parts and high heat needs lubrication just like engine oil.



There is a Ginormous difference between Re-manufactured vs Rebuild transmission. Don't be fooled. Always GO Re-manufactured.

There are half a dozen Big Transmission Re-manufactured shops scattered throughout USA.


Your X5 transmission has an extra Transfer Case used for the AWD (front wheel) These shops below do not warranty or fix the Transfer Case.

Despite the claims of 3 year/100,000 miles warranty advertised on their website...
These Shops do NOT provide any warranty DIRECTLY to the END Customer.
They only provide to the local Distributor and you can not file a Claim with these MFG above. Your warranty is with the installer... NOT the MFG.


The World is moving away from Manual Transmission/Clutch so everybody should learn to fix an Auto Transmission.

Unfortunately some are stuck with GM. However, some e53 models have ZF Transmission. In this case, you're in luck. You can buy a ZF transmission from ZF MFG and Genuine OE/OEM parts from ZF.
