My 2003 Toyota Corolla with 175,000 miles was showing the check engine light. My friend ran a check and the code P0770 came up, which is Shift Solenoid 'E' Malfunction. When I'm on the freeway, I do notice my car is slow on accelerating, but my MPG is fine. How much would it cost to get this fix? Also, would I fail the California SMOG check? My friend removed the check engine light and it hasn't reappeared (It's been a good 500 miles without it reappearing, but my car is still slow at accelerating). Thanks guys!

It depends on how he 'removed' the CEL light, in the process of a Calif smog check they test the CEL, and if it is inop you fail. Now if he removed it by fixing/replacing the solenoid, you are fine. Cost? Very difficult to estimate. The solenoid is only $15 but it's inside, the pan has to come off, and there is some labor time there. Click on this, '3' is 'E'

@DavidH25, he didn't fix anything. He just turned off the code. My car is just slow at accelerating; I don't think it's releasing emissions though. Would I fail the California Smog test for a 'E' Solenoid problem?

Now that one moorejake is a good question, any help here? But to clear the CEL whatever make it light up had to have been fixed or the CEL will re-appear. Unless it was disabled that is.

DavidH25, id like to know where you found the solenoid for $15... i am in need of one as well.... please email me the link or info thakauz@gmail.com thanks for the pix too

I need the part that you said for $15 can you please also email to me ermanvelasquez.18@hotmail.com

were there any updates to this?

Hi I need these shift solenoid ,can I have some info. where Ican get them please , my email avinashparay@yahoo.com or whatsapp 18687276513. Thank you.

I have the same code about the E transmission solenoid on my dad's 2000 Toyota Avalon (6 cylinder) plus a few other codes, with one stating that it has a random misfire and a engine misfire on cylinder #4. The car runs rough at idle and it also appears to shift gears a bit slow when accelerating, but can still be driven, although engine stumbles and does not run smoothly. It turns out that when I replaced with new spark plugs and also a new coil plug on cylinder #4, all the codes went away, including the transmission E solenoid code! There was nothing wrong with the car's transmission, except for the misfire on cylinder #4, causing it to runs roughly and in turn, triggering the FALSE transmission solenoid code. I highly suggest you change with new spark plugs FIRST and if needed, change the coil plug on the particular cylinder(s) that's causing the engine misfire if there are codes regarding engine misfire besides the code for the transmission solenoid. Ebay and Amazon have the BEST prices for aftermarket coil plugs and other engine electrical parts and sensors. You can save so much money if you're on a tight budget for car repairs.

Please need help I need that solenoid where I can find it for $15.00?? Please replay to redtail2274@att.net I will appreciated!!

P0770 refers to shift solenoid E. Its a performance code, not a circuit code. Shift solenoid E is used for engaging the torque converter clutch which occurs above 45mph at highway speeds when youre cruising. Basically, the clutch comes on to "lock" the torque converter so it no longer slips. Now, since this is a performance code, there are several possible problems. It could be a bad Shift Solenoid E. If youre going to venture into replacing it, I would highly reccomend you get one brand new from Toyota. Im unsure of the price on the solenoid, but generally, shift solenoids from toyota range between $200 - $400. If you go b uy the Chinese knockoff, it may or may not work. If it throws the same code again after replaceing it with an aftermarket solenoid, youre not going to know if its another problem or a junk solenoid. And as a professional in the transmission industry for 28 years, anything from China is GARBAGE. Now, As someone stated previously, if your car is misfiring, this can cause performance issues with the converter clutch. It may bounce in and out of lock up, or it may never even get into lock up. So if you have any misfire conditions, I strongly advise you to fix those first. If its still not corrected, you can give the solenoid a shot. If that still doesnt fix the problem, Id reccomend taking it to a reputable transmission shop for further diagnosis and repairs. On high mileage vehicles, its always possible that the converter clutch has a problem, or that the hydraulics that engage the converter clutch are worn out.

I’m on the same boat, the thing is I just replaced EVERYTHING; coils, plugs, cat & O2’s, all 4 injectors, air filter, valve cover gasket and new battery. Yet it’s still misfiring & 300 miles into it the only code that came back is the tranny one. It may have a vacuum leak, not sure. I’m about to throw in the towel and drop it off at a shop this week. Like mentioned above tranny guy told me to take care of misfire before probing into transmission solenoid. He gave me a quote of $150 on labor plus parts which is reasonable and honest. So yeah, I’ll post an update this week.
