How does a solenoid work in a 6 speed transmission?
Oddly enough, these 6-speed solenoids are fed regulated, non-orificed line pressure from the manual valve. You can count this as your little-known and even less-cared-for fact of the day, but it’s an extremely important one.
How to replace solenoids on a Mercedes 7 speed transmission?
Replacing the solenoids from the Mercedes-Benz 7-speed transmission is very easy once you remove the valve body from the transmission. You will need to Torx T-40 bit to remove the bolt that holds the clamp in place. Once the clamp (bracket) is removed, you can pull the solenoids straight up to remove them. Reinstall the solenoids in reverse order.
How is resistance measured on transmission shift solenoid?
Next up, set the voltmeter to measuring resistance and then turn the knob to 200. You can either choose to do this beforehand or do it on the spot – that’s entirely up to you. If there are any discrepancies in its measurement, there’s a risk you could be on the path to misdiagnosing the solenoid completely.
How to diagnose a problem with a solenoid?
The key to diagnosing the problem right the first time is verifying solenoid commands and gear ratios with a thorough road test and capable scan tool. The trouble area that these three transmissions have in common relates to the feed that these solenoids are provided.

Is there a quick fix for transmission shift solenoid?
You may also do this procedure, with the engine running in park, to flush out dirt from the solenoid. You may ground the solenoid inside the car, at the transmission connector. This test is also good for duty cycle controlled solenoids. This concludes the Transmission Shift Solenoid Quick-Fix. Loading…
Where are the shift solenoids located in a car?
There are two or more shift solenoids inside your transmission. The solenoids are typically integrated into the transmission valve body. If one or more of them fails, you’ll likely notice a handful of car problems.
