What to do about transmission leak in sonnax 6R80?

The valve can be easily removed from the vent with a pick. If you happen to remove the entire vent from the transmission when you are attempting to remove only the cap, a plastic GM 350 vent can be substituted without issue. You may want to remove the check valve from the vent before attempting to fix any of the leaks.

What happens if you have a vacuum sensor leak?

A MAP sensor vacuum leak can upset ignition timing and engine stability and efficiency. A vacuum leak can also prevent an EGR valve from opening, cause engine overheating, and increase harmful emissions. This type of leak can also affect the Positive Crankcase Ventilation (PCV) system.

What causes a vacuum line to leak at idle?

Having a good seal from the piston rings most people understand, but when running a very large and aggressive cam, often there will be more overlap in the duration between intake and exhaust valves that will cause a loss of vacuum at idle. This loss of vacuum causes the motor to struggle when idling at low RPM’s.

How do you remove the solenoid from a VANOS unit?

This photo shows the removal of the VANOS unit solenoid. The solenoid opens a valve that allows oil into the VANOS unit, which then advances the camshaft timing. Use a 32-millimeter wrench to loosen the solenoid from the VANOS unit housing. The inset on the lower left shows the inside of the solenoid.

What to do if your transmission solenoid is stuck?

If the trouble code tells us that it’s stuck or an electrical problem, it is most likely a wiring or shift solenoid problem. Many shift solenoid-related codes can be solved by doing a transmission fluid replacement or carrying out a transmission flush. A transmission fluid change is often not that expensive and worth doing.

Can a transbrake solenoid be ground to the case?

Ensure that you have a proper ground . Grounding to the chassis or directly to the battery is preferred. Do no ground the solenoid to the transmission case. There is some evidence that the grounding of the solenoid to the case can cause electrical arcing within the planetary gears.

How much does it cost to replace a solenoid pack?

A single shift solenoid’s replacement cost is between 100$ to 350$ and a shift solenoid pack costs between 400$ to 700$, including transmission fluid, filter, parts, and labor work. The replacement cost of a shift solenoid replacement depends a lot on what car model and transmission model you have.

What causes transmission solenoid to not get both 12 volts and ground?

Measure that you get both 12 volts and ground to the shift solenoid at the plug on the transmission on the affected pin. If you do not get both 12 volts and ground – you may have a wiring problem or a faulty TCM ( transmission control unit ).
