   I just purchased a 2007 double cab Tundra 5.7. Truck has 106,000 miles. CarFax shows 1 owner, 54 dealership maintenance records. Title shows owner is 69 years old. The first week of driving, I noticed a very light shudder between 45- 60 mph. It only happened like 5 or 6 times for less than a second each time. Initially I thought I had driven over a rough patch in the road. Drove it cold one morning and could make it happen everytime when it shifted between 5th and 6th gear, so I knew there was an issue. Brought it back to the dealer. He said he would take care of it. When I picked up the truck, he said he just drained and filled the tranny. No shudder, but my check engine light and traction control light came on and my vsc light and 4 lo light started flashing. Went back and forth with dealership twice. Both times they reset the fluid level, and the last time they said they changed the fluid and filer. Still no shudder, but lights came back on. The dealer is now bringing it to a reputable transmission shop. Anyone have this issue or know anything about it?

   Any CELs? If you don’t have an odb2 reader go to autozone or a place like it, they’ll read the codes for free. Even if no CEL is on, a code could be pending, so have it checked. Then go from there on next steps. Luck and enjoy the Toyotas. : ^ ))))

   Thanks for your replies. The check engine light is on. The code is p2757. It is the torque converter clutch solenoid circuit code. (possible the solenoid is stuck off, could be electrical or mechanical) This code could be for many reasons. The code came on after the dealership changed the transmission fluid. Just wondering if anyone has done a tranny fluid change or flush, or tried adjusting the fluid level and got this code. I spent about 10 years as a mechanic, about 23 years ago, and worked on my own vehicles most of my 46 years and I have never encountered an issue after a simple atf or motor oil change. But I am unfamiliar with these toyota vehicles . So I am just curious if anyone has had a similar issue after the atf was changed. Thanks again

   Also, I do have a scan tool. And after this issue I purchased the techstream software and used it to check the CEL. It did show the code was pending before it came back on later that day.

   This issue was finally fixed. The transmission shop had diagnosed that the torque converter had excessive slipping at the lower rpm ranges. They do have very sophisticated diagnostic equipment. The dealer first decided to R&R the TC. Hoping it was the cause of the slipping. It was certainly a worn component, but the lights and same code returned. The transmission shop ran all the tests again and determined that the values inside the valve body were changed, but there were still faults with internal pressures. It was the valve body that was worn out. They replaced the valve body along with all the solenoids. Lights out! I hope this can help someone. The parts and labor for the valve body was $1600.00, covered by the dealership. Also, I found this during my research. It is very interesting. https://www.sonnax.com/tech_resourc…aults-in-a761-ab60-a960-6-speed-transmissions

   about how much did they get u? I am getting this code again after only a year. This time last year I got the P2757 & was told I needed a trans rebuild, so I looked at IPT imports. My transmission guy spoke with them & agreed to do the install. I missed my warranty by 19days to say the least. The article u posted above would make sense & I believe still even with the IPT valve body would be a issue. Seems once it gets cold I start to have transmission issues.

   Not sure what you mean by «about how much did they get you?» I have had zero issues with this transmission since the initial drain and fill, other than check engine light coming on. The CEL continued to come on until they replaced the torque converter and finally the valve body. I am coming up on a year and have driven about 16,000 miles since. I did have the CEL come on about 6 months ago, and the same code p2757 came up along with the ECU malfunction code and the air injector pump code. I used the Hewitt Technologies secondary air pump bypass module, after determining the pumps were failing due to water being in them, typical issue with these trucks. Being concerned about the p2757 code coming back, I also installed the Magnefine inline transmission filter. I knew pretty much every ounce of the old fluid was replaced with new WS fluid, because the torque converter was replaced along with the valve body and multiple transmission fluid changes trying to fix the issue. So I decided to start using the Magnefine filters from now on. No CEL’s since. I am planning on replacing the inline filter and doing a transmission flush at around 130,000 miles and replacing the WS fluid with Amsoil signature series transmission fluid. From my research online, There are multiple sensors and solenoids that can throw this code, and these sealed transmissions are very sensitive to the fluid and fluid level. From what I understand, the crankshaft position sensor, internal solenoids and transmission out put sensor can all sense the torque converter is not locking up, even for a fraction of a second, and throw the code. Also the ECU could be malfunctioning. In my opinion the worst part of this is Toyotas’ recommendation that the fluid is «lifetime» or I have heard 100,000 miles. That is BS. These transmission are great and heavy duty, but again, in my opinion, with how sensitive these sensors and solenoid valve are, I will not ever go over 40 to 50 thousand miles without changing the fluid, and I will continue to change my inline filter yearly. Good luck, and if I didn’t answer your question, I just didn’t understand what you were asking.

   I was just curious on the cost but that really seems inconsequential. So since u seem much more versed with this code & subject of transmission. So I’ll ask u, last year maybe 1.5yr ago I got a code a AT code after leaking out ATF from my pan after parking on a incline. Dealer says “don’t work on trans, $8k for new transmission”. I then started to look at IPT valve bodies & asked my trans guy to get one and put it on, all and all I got a “beefed up torque converter, new gears, ipt valve body”, ran good for a year or so thru the summer & the minute it got cold it started acting up again, the following week I had to tow my boat 4-5hrs & it took 8-9hrs cause I kept having to stop & let the trans cool off (seems to get hot only in winter months). Now that it’s cold again it started weeping ATF from the heater thermostat unit, I replaced the 4 o-rings on that and put the 4oz lost durn plus about 6oz that I assumed I’d lost durn the slow leak. But to be sure I leveled the truck, pinned the thermostat, shifted slowly threw the gears & waited for it to get between the recommended 115-135°F on my bullydog & pulled the check plug to check the level, when I pulled it ATF came pouring out, I stopped it after 3qts came out in 90sec in a steady stream. I put back the 3qts knowing that no atf other then the few oz I put back after changing the o-rings was added since the rebuild, so something must be wrong. About 20miles later I get the P2757 code and am freaking out cause I don’t wanna dump another $3800-5000 into it. What could be going on? Clogged filter causing the fluid not to get drawn up into the trans? Something else that u mentioned above? I’m not super transmission savy but would like to know what to ask the trans guy to look for. Specs of truck below

   -2007 tundra crewmax 5.7L Supercharged from Toyota at the factory
   -Bullydog unit with performance shifting tune
   -AB60F transmission with relatively new valve body (IPT) and torque

    The cost was covered by the used car dealer, because the problem occured during the first couple days I bought the truck, and the dealer was a decent person that valued his reputation. He did show me the bill for the valve body for $1600.00, I don’t know what the torque converter cost him though. Anything I say is just an educated guess, without any hands on diagnosis, but. A clogged filter is possible, but highly unlikley, because the «filters» in these transmissions are actually just screens. Back in the day, transmissions had actual filters, paper or synthetic elements that would trap small, damaging particles. For whatever reason, with these newer, sealed trannies, it’s just a screen that would only keep larger particles out of the working parts of the tranny. If this screen is clogged, you have catastrophic damage in there. With the over heating and leakage, I would suspect a blockage in the tranny fluid heater and or the tranny fluid thermostat unit or the tranny cooler. I cannot come up with a reason, other than overfilling, that 3 quarts of fluid came out of your tranny while checking the fluid. I would use the obdII jumper method to check the fluid though. That way the trucks ECU is telling you the transmission fluid is at the right temp. to check it. This fluid expands quite a bit as it heats up, and if too hot will seem as though it is overfilled. Although I don’t believe it would be 3 qts. over. I’m sure you have seen the TSB for checking the fluid level, but I attached it anyway. Best of luck to you

    One thing I forgot to mention, although unlikley, because you did not recently replace the tranny filter. There is an O-ring that seals the pick-up/filter to the transmission. If the O-ring is not sealing the filter to the transmission, basically sucking air instead of fluid. This would not allow the proper amount of fluid to be picked up into the tranny, and leave excessive amounts of fluid in the pan. Again, hope this helps.

    Hello Tacticaldeath,

    thanks for this. I recently (last week) brought a 2008 tundra with the exactly same issue. I got the shudder between 45-60 mph and thought the same thing as you, and 300 miles later, the check engine light came, traction control light and vsc light came on. I have not done any work to it… not sure where to start either. Any word of advice?

    Thanks

    You’re likely in for a valve body and possible a torque converter then.

    Price them both out. You may find that the dealership won’t do the work. I would pay attention to the reviews of any independent
    shops you contact. Also put a plastic bin in the bed and tell them you want the old valve body and TC put in there when they are done.

    First, check or have the fluid level checked. Make sure it’s at the proper level. Also, make sure it is clean and not burned out. If it looks dirty or smells burnt, the have it changed. If the fluid appears good, try driving the truck in sequential mode, selecting 5th gear. (ALL THE TIME) By doing this the truck will not use 6th gear. See if the shudder stops and the engine light stops coming on, Then I believe you have the same problem I have. I believe it is the valve body and TCC solenoid. This is a known issue with this transmission.

    Hi understood. Thank you. What is the reason why we want back the old valve body and TC?

    Thanks

    You do this so the mechanic can prove to you that he/she did indeed replace the parts your requested.

    Some shady shops will say they did the job and that they «tossed» the old part parts in the trash bin.
