    Codes P0705 P0983 P0504 P0571. Does this mean the only fix is rebuild the transmission? From what I been reading on here seems like just changing the parts will not fix the inevitable..........

    P0705 is a Range Sensor Code
    P0983 is SS D Circuit High
    P0504 is Brake switch Correlation code
    P0571 is Brake switch A code
    So the first 2 codes are for the trans not necessary saying it needs to be rebuilt can be bad shift solenoid D the other 2 codes are possible brake switch or harness.
    But first check for blown fuses those are weird codes to get on a toyota well maybe not the P0983 but the other 3 are

    Check all the small stuff like fuses, connectors and grounds. Give a good visual inspection. Is there something wrong that you can tell by driving? If all seems normal, clear codes and then drive around without the overdrive on and see if codes come back. If nothing then try it in overdive and see if it throws codes then.

    Ok. Checked fuses. All ok. Not sure where to turn overdrive off on a 2007 tundra 5.7 I looked at ground cable at battery. I have owned this truck since 125k miles. Just had it on a lift and looked at all under carriage All looks good. Needs a driveshaft support and tailshaft seal on transmission.

    Be forewarned. If your codes genuinely represent transmission issues, Toyota dealers typically will not repair transmissions. If an owner comes in with a transmission problem, their solution is to replace the transmission with a Toyota certified remanufactured transmission.

    To minimize expense, you'll be ahead to take it to an honest, reputable transmission shop if internal repairs are possible. If transmission replacement is necessary (to be determined), then I would trust a Toyota reman transmission better than others.

    You said that the transmission needs a tail shaft seal. I would check the fluid level in the transmission first.

    Thank all who answered. I am in the process of changing out the seal and driveshaft support which was bad also. Then I’m going to a dealer for a transmission flush.

    I’ll report back after that.

    Update...... I changed the leaky seal on the transfer case 4x4 not transmission seal (silly me). Changed worn out driveshaft support bearing. Then I was off to dealer and flushed transmission (16 qts) $240 later. Everything was reset and fine except shift indicater ( no lighted P R N D ) and 4lo light is on. Put it in neutral 4lo light goes out and indicator lights up. Put it back in drive light goes out unless I put forward pressure on the shifter then the D lights up. I only have this issue at cold start. If I baby the shifter by hand til transmission is up to temp the problem never happens. Any ideas?????

    Thanks in advance.
