When I get to 20 to 25 mph I hear a reving noise... the engine irunning fine, the transmission is shifting fine... This is my only form of getting around

The solenoid is located inside the transmission on the valve body.

good old-- needs a new transmission answer to a problem--
codes do not recommend a new transmission but give causes for the problem
like servo, solenoid, pressure , torque converter clutch etc, possible mechanical failure
with the transmission operating fine after 10 mph there is no mechanical problems requiring a new transmission so it is electronic issues that have to be addressed
the issues could be a simple broken vacuum hose to the transmission actuator, wiring connections ( corroded , water , loose broken wires)
Take it to an accredited professional transmission specialist shop and have a proper diagnosis and quote done

I would guess that something inside of the transmission has failed and there is no longer a mechanical connection between the motor and the drive axles regardless of what gear you attempt to move in.[sheared splines, broken planetary, etc.] Often when this happens you won't hear any kind of noise because of the failed parts being inside the transmission case...instead the car just won't go anymore. You could have a CV drive axle joint that has failed but generally they will make some noticable rattling or grinding noise as they churn away when you try to go forward or reverse. If something has failed inside of the transmission then the transmission will need to be removed and repaired. It if is just a drive axle joint that has failed then that can be replaced without doing anything to the transmission. Hope this helps and good luck!

CLUNKING NOISE IS BAD CV JOINT.

check for a problem transmission /engine mount

Sounds like your transmission is on the fritz. Try changing the fluid and filter see if that helps. If that doesnt try a can of anti slip from any good parts place (Napa). If this dosent help it's time for a rebuild on the transmission

Hey Gary, take your car and get the transmission fluid and filter changed immediately... you will be glad you did...(expensive lessons speaking!!!)

Have you checked your belts? A piece of belt may have come off and been slapping under your hood, and then fell off completely. While it was slapping, your computer would have detected the slow down of pulleys etc. and caused your engine light to come on. Then when the piece broke off, everything would be back to normal. Let me know!

There only one problem wrong.You dont let your transmission warm up.You transmission has you warm up just like the motor.Try this and i promise when you take off it will shift like no other

May be a bad rear end, Gear in rear may be broken check rear. Good luck and thanks for using FIX YA
