My transmission shift normal kind of hard when it's cold but smooth in general . Replaced the fluid and filter advised by AutoZone when I brought for fix finder . I changed spark plugs as well and after the light went away and came back after I filled up gas . I was able to erase with scan tool waiting for it to come back . Any advice ,fixes or tips ?
Code p2757-2012 Corolla 1.8 a/t
mileage please
125k
Take it to a transmission shop
I'll try but the code has not come back yet and thank you I've looked at the site before
This might sound weird, but try cleaning your MAF sensor and your throttle body. I have a 2006 Toyota Sienna and it was having some hesitation at low speeds, and cleaning my MAF sensor and my throttle body helped a whole lot.
Hello all and thank you for the responses there's a kind of known problem with the computer pcm/tcm . What I decided to do today,the p2757 code came back, was disconnect the battery and then the computer connectors and i work in IT so I had some electronic safe cleaners on hand I only wiped the connections both on connector and port waited a bit . Connected everything back up . Took it for a drive and transmission shifts very smoothly no erratic upshifts or hard down shifts . They didn't look dirty on connectors but maybe there was slight corrosion and dirty I was able to clean up . Hopping that the code doesn't come back .I'll keep everyone up to date . If anyone has anything to add still welcome to advice
Update took it in for diagnosis it's looking like a faulty computer or transmission rebuild didn't think this would happen to my Corolla {black}:excitement: 🙁
It's official the torque converter is faulty and Toyota knew about it . Can't believe they'd do this to people who's have trust in the brand gonna cost 2000 ish to replace the torque converter but mechanics from different shops say I'll need a full rebuild and or new transmission any where from 3-6 thousand with labor . I love skotty kilmer information but this is a turning point for me and Toyota . Not skotty tho
Is it still shifting smooth at the moment? If yes, get rid of it. Put it up for sale & see what happens..
