what is a shift control solenoid valve on an auto transmission?

Looks like you don't know much about ATs.

there are two shift control solenoids on most automatic transmissions. They are identified as "Shift Solenoid A" and "Shift Solenoid B".An automatic transmission or transaxle gets their different gears by applying hydraulic pressure to or releasing hydraulic pressure from the internal mechanisms that hold gear sets engaged. Hydraulic pressure is also used to apply or release the internal clutches for the gear sets and allows for the shifts between gears.The solenoids are electrically applied to block pressure lines and un-applied to open the line for pressure. Depending on which solenoids are enegized (blocking a passage) and de-energized (allowing pressure) there are four possible combinations of ways for SSA and SSB to allow fluid to flow (On-On; On-Off; Off-Off; and Off-On). Those combinations give you the separate gears in your automatic transmission based on the routing of fluid through the transmission's internal passage ways to the holding devices or gear sets. When a solenoid stops working you typically hear that the transmission isn't shifting into a gear.Hope that answers your question

will the solenoid valve have anything to do with my problem.I need help, i have a 1993 honda accord automatic transmission. The car starts kinda ruff, its very hard to get it to go from park to drive. When you drive the car for 5mins you can feel the transmission starting to slip after ten mins it slips and will not go back in gear. If i cut the car off for 1 min, it starts fine and will shift in gear and after 5 mins the cycle repeats itself until you get to your destination. I have read post linking this problem to the shift cable or the electronic solenoid. Or the transmission converter. Can anyone point me in the right direction. The transmission fluid is fine and there are no blinking lights or check engine light.

Does your drive light near the shifter start blinking ?

Same problem im having, this light is blinking on the indicator on dash....
