Code P0770 Toyota Description

The P0770 diagnostic trouble code (DTC) for Toyota vehicles indicates a malfunction with Shift Solenoid 'E'. The shift solenoids are responsible for controlling the hydraulic pressure in the transmission, which in turn helps to engage the gears for smooth shifting. When Shift Solenoid 'E' malfunctions, it can result in issues with shifting gears, leading to poor performance, rough shifting, or even the transmission getting stuck in a single gear. This can have a significant impact on the vehicle's drivability and overall performance.

  • which one is shift solenoid e

  • my 1997 toyota camry came up w/pending code p0770 shift solonoid e malfuntion, do I need to change the transmission or do I need to change fluids.

  • You could start by changing the transmission fluid. It's probably worth trying changing the fluid first.

  • yes one solenoid was replaced, think it was the p0770

  • can someone please tell me how much it will cost to fix the p0770 code.
    Thanks

  • can you please share what was the solution for this code and how much it cost you

  • there are several shift solenoids in transmissions and 3+ and I am still trying to figure out which is "e"
    There is a secret coding that no shop r auto parts store wants to reveal. :-(
    There are some sites to get the parts cheaper if we can just break the code for parts numbers.
    Autozone quoted me $455 for this part and I find similar ones online for $156 but will not order until I can cross reference the part number. replacing is easier than believed. Remove fluid pan and there are the solenoids. Unplug, remove screw that holds in place and replace. and I will change fluid and filter anyways.

  • you can get the part number from your local toyota dealer.

  • If you have the v6 model there will be 6 shift solenoids. They will be cheaper at your local Toyota dealership. I would recommend that you go to a shop to have your codes read, they will tell you what number it is as their scanner will pick up your vehicle make and model. Auto zone has generic scanners.

  • I put a pint of Marvel Mystery oil in my Tundra and the light went off in 20 seconds.
    Shifts like a dream now.

  • Hi,

    I'm going to try this repair myself. Any idea what the part number is for replacement? 2003 toy corolla
