Transfer case removal

first remove both front and rear driveshafts. Then remove skid plate underneath transfer case. Remember to unplug the electric motor wiring harness for explorers with electronic four wheel drive switching. Remove vacuum line on the top of transfer case. Unbolt Speedometer cable mount from top/rear of transfer case. Remove five bolts connecting the transfer case to the transmission, this step will cause some transmission fluid to leak from the shaft housing (approx. half a litre) so place a drain pan underneath. Remember to either place a jack or wood blocking under transfer case before removing the last bolt connecting the transfer case as it is heavy (approx. 80-90 lbs.).

Speedometer goes all the way up to 120 when first initially starting up. . .then it doesn't work at all

Your Vehicle Speed Output Sensor or Sensors' Eelctrical Connections is malfunctioning.
It is very easily accessed, located on the Transmission; and easily removed and installed.
However before replacing:
Check the electrical connection(s). Unplug and check both sides of the connections for corrosion and oxidation (white stuff). Clean, reinstall and recheck operations.
If this does not fix the problem:
Unplug this Sensor and remove it. Clean off the interior end. Reinstall, replug and recheck operations.
If this does not fix the problem:
Remove and Replace.
I took the liberty to look up the Parts, Availablity, and Pricing. (NO! I do not work for any of these stores/companies)
This is the OUTPUT SENSOR.
Advance Auto Part #S8201 (for Automatic Transmission) for around $17.
O'reilly's Part #S8201 (for Automatic Transmission) for around $18.
Autozone did not have an Output sensor listed, only Input for automatic transmissions.
1) Look the Part up on their web sites to gain insight on what the Part will look like when looking for on the Transmission.
2) Take the Part out and take it with you when purchasing the Part. Compare the original Part with the one you are purchasing to make sure you are getting the right Part.

Let me know if this helped, or if you have additional information or questions. Feel free to contact me at!

Is their a recall on the 2001 x5 bmw transmission and also the brake lights.

Don't know about recalls, but BMW uses GM 6L80E automatic transmissions. These clunkers were built to carmakers' specifications by GM for MANY manufacturers, including BMW, Honda, Sterling, Rolls get the picture.
These transmissions are mechanical and eletrical/electronic nightmares which fail frequently. Many of the problems lie in the carmakers' specifications, asking the thing to do way too many cutesy things to convey a sense of luxury, power, and superiority. They have way too many parts for the task of moving an automobile, and when they fail, they frequently go into a pre-programmed "Limp Home" mode, allowing the use of one forward gear only at a low speed.
BMW is a fine automobile; too bad they over-engineered and contracted out the transmissions.

Electrical connection for the pressur control

A transmission solenoid is an electro-hydraulic valve that controls fluid flow into and throughout an automatic transmission. Solenoids can be normally open or normally closed. They operate via a voltage or current supplied via the transmission computer or controller. Transmission solenoids are usually installed in a transmission valve body, Transmission Control Unit, or transmission control module.

Speedometer erratic...replaced fuse and was ok for 24 hours Honda Civic 1998

Your speedometer is driven by a speed sensor that is on the top side of the transmission. It would be worth your trouble to locate it, and unplug the electrical connector to see if it is clean and connected well. If everything looks ok, you are down to it or the actual speedometer unit.

Usually, if the transmission speed sensor is bad, you have other driveability issues too, so you might have just a minor problem.
