Transmission shifting issue

Have you had the computer scanned for codes yet?Sounds like the transmission is going into limp mode and when you cycle the key it goes out of limp mode.

you can take to any parts stores and they will check. the codes for free.make sure the fluid is full.check it with it running.this also could be cause by the converter staying engaged as you come to a stop.if there are no codes take it to two transmission shops and see what they say it needs.then get back with me.good luck Steve, i hope this helps.thanks for using 2CarPros.

Just found time to have the code scanned here is what came up:
P0841 Transmission Fluid Sensor switch A
P1776 Transmission solenoid switch valve lacked L/R Position
P0700 Transmission Control System

Any direction would be helpful. I'm trying to get this car in shape for my son to take back to college. If these are parts that can be replaced any idea what the cost and who should I contact, general auto repair or transmission place.
Thanks,
Steve

You could just have a bad solenoid. does the code come right back as soon as you clear the codes?

Good afternoon,

The first thing I would do is change the fluid and filter in the transmission. If the fluid is dirty and some dirt is in the valve body, it will do this.

As far as the code, I posted the possibilities below but you will need a scan tool to monitor the live data.

I attached a wiring diagram for you as well that needs to be checked.

Both codes are wiring related. That means it could be a harness issue internally or the control unit feeding voltage to the sensors.

My car recently has an issue sometimes with the rpm's going over 3.
The car isn't downshifting.
When this happens the engine revs and sounds strained. Once I'm able to pull over, I shut the car off, turn it on and it's fine.

Please help! My husband checked the transmission fluid and that was fine.

Have any warning lights come on? It sounds like it isn't shifting.

The engine light is on now, however sometimes it comes on and other times it's off. The car runs just fine other than that. Going to work this morning it didn't do a thing, but the engine light did turn on.
But last night going home it did it. I pulled over and shut the car off, waited, turned it on and it was just fine.

When the check engine light is on, you have to have the computer scanned. Most parts stores will scan it for free.
