Try changing your PCV valve it messes with the idle control. and shifting prob is likely in tranny and may not be related at all. try PCV valve and have your tranny serviced.
automatic transmissions have a slave valve to control shifting
Not likely. It would mainly cause a poor running engine.
whats the difference between soleniod valve and control valve
could be a bad modulator valve but i would change filter and fluid in transmission first
There is no difference
There is no difference between check valve and NRV, both are same
Most likely pressure control solenoid in transmission....Easily tested with proper scan tool ALSO try changing EGR valve. Will REALLY HELP!!!! I just changed mine, all my hard shifting and jerking in reverse went away.
The year, make and engine info would be helpful.
What are you doing shifting gears or changing the slave cylinder? If your going thou the gears 1 for 1 and for the ceilnder till all the air is out but make shore to open and close the valve as your pumping it.
Your meaning is unclear. Your system will already have pressure switch, -why would you need a pressure valve?- or are you unaware of the difference between a valve and a switch.
If it a manual transmission it could be fluid level/needs changing, shifting fork/linkage or syncro issues. If it is an automatic, the fluid level/condition can affect shifting, also if the valves in the valve body are sticking. The transmission can also just need rebuilding, clutches are worn.
The Gate valve is the stop valve & the Globe valve is the fluid Regulating valve.
Basically a side entry valve would be in two or three parts, and a top entry valve is a compelete housing, the top entry valve would be used where access is difficult to remove and work on the valve, you can work on a top entry while it is on line where as the side entry valve would have to be removed
egr valve may be clogged or bent. where do i find the egr valve on my 93 Saturn sc2?
On a 1997 Volkswagen Jetta, the shifting solenoids are situated inside the valve body of the transmission. The valve body is the brain of the transmission.
XV is shutoff valve UV is under control valve
try the idel air control valve
They are just about the same
A 2000 Chevrolet Lumina has a modulator valve located on the side of the transmission. It is designed to control pressure inside the transmission and adjust shifting.
no you cant
Engine light on
possible 12 accumalator spring is broken.you can get to it by removing the valve body.If you have no transmission experience I would let a shop handle it
