China wholesale TU-1A90 thermal wax actuator for automobile thermostat for Manila Manufacturers Detail:
1. Operation Principle
The Thermostatic Wax that has been sealed in shell body induces expansion by a given temperature, and inner rubber seal part drives its handspike to move under expansion pressure to realize a transition from thermal energy into mechanical energy. The Thermostatic Wax brings an upward movement to its handspike, and automatic control of various function are realized by use of upward movement of handspike. The return of handspike is accomplished by negative load in a given returned temperature.
2. Characteristic
(1)Small body size, occupied limited space, and its size and structure may be designed in according to the location where needs to work.
(2)Temperature control is reliable and nicety
(3)No shaking and tranquilization in working condition.
(4)The element doesn’t need special maintenance.
(5)Working life is long.
3.Main Technical Parameters
(1)Handspike’s height may be confirmed by drawing and technical parameters
(2)Handspike movement is relatives to the temperature range of the element, and the effective distance range is from 1.5mm to 20 mm.
(3)Temperature control range of thermal wax actuator is between –20 ~ 230℃.
(4)Lag phenomenon is generally 1 ~ 2℃. Friction of each component part and lag of the component part temperature cause a lag phenomenon. Because there is a difference between up and down curve of traveling distance.
(5)Loading force of thermal wax actuator is difference, it depends on its’ shell size.

This is a quick time lapse video of me replacing the solenoids on my 2004 545i transmission valve body. Sorry, I had the resolution set as high as it would go on my camera on accident, so I ran out of memory card space before I got all the way through this. I was originally going to show a lot more detail on taking the valve body/mechatronics apart and how the replace the solenoids & reinstall everything. Hopefully this still helps someone though.
Typically BMW will tell you to replace the entire transmission when there are any issues or at the very least, sell you an entirely new valve body/mechatronics unit at the cost of a kidney on the black market. If you’re a decent DIY’er you might have even found rebuilt mechatronics/valve bodies online for $1500 or so. Most common issues can be resolved with just new EDS solenoids (pressure regulating solenoids), which can be found on the internet. I got mine from thectsc.com in one of the kits for under $500.
My issues were slow going into reverse (3 to 4 seconds), jerky shifts, especially 3 to 2 and 5 to 6, and transmission errors under hard acceleration during a 4 to 5 shift. All issues have been resolved. I can barely tell when it even shifts anymore it’s so smooth now.
Oh, and mine has 181K MILES ON THE ORIGINAL TRANSMISSION. The hard parts of these transmissions are great, it’s the solenoids that fail early due to BMW’s “lifetime transmission fluid” joke.
MAKE SURE YOU RESET ALL OF THE ADAPTATIONS IN INPA BEFORE DRIVING THE CAR. Do not rely on the “hold the accelerator to the floor with the engine off for 30 seconds” trick. It has never worked like a real reset for me.
Please comment with any questions. Its a pretty simple job, just messy with all the transmission fluid that keeps dripping out.
