i got an 06 tundra that damn near chrips the tires on the 4-5 downshift, has a soft 4-5 upshift, and has a shudder on the 1-2 upshift at low throttles (this kinda fixed itself, but the shift is definitely still soft), it threw the p2714 code and went into limp mode for a while. now the code and limp mode is gone... I tried to diagnose the solenoids, but after measuring and testing them all, they seemed perfect. the problem is kinda my fault, both of the problems started when I torque braked it and the RPMS flew up, I tried to figure out what was going on from this video but assuming the 1-2 and 4-5 shift problems are related due to the initial failure, I came up with nothing. does anyone have an idea of what is going on here.
Would a worn valve body cause a hard downshift to first? Got the slt code after drain fill and filter replacement, had that selenoid replaced and getting intermittent hard shifts into first. 05 sequoia limited 4wd a750f.
Usually, that is a high idle problem or a sprag issue. The TCM usually commands the shift to first gear at zero miles/Km. literally almost stopped. check the command, if its coming early you might have a vss issue, or tires to big/small
Recently had a problem with 06 Gx470 A750F stating shift solenoid B control circuit low, replaced the S2 but problem did not go away, wiring and everything is intact. No slipping from transmission, only makes a loud thump from reverse to drive vice versa. Any solution? Would replacing the valve body solve this?
Usually circuit low issues are voltage issues between the TCM and the solenoid. I would verify the voltage at the harness during operation. Should be pion 15 at the transmission harness and the E6 ECM connector pin 10 Shifting from 1st to 5th is performed in combination with "ON" and "OFF" operation of the shift solenoid valves SL1, SL2, S1, S2 and SR which are controlled by the ECM. If an open or short circuit occurs in either of the shift solenoid valves, the ECM controls the remaining normal shift solenoid valves to allow the vehicle to be operated smoothly (see FAIL-SAFE TABLE ).

Do you know how many clicks the torque converter takes to seat properly on an a750f? Mine has seated 3 clicks but tranny isn't wanting to mate to the block.
I don't understand what you mean by clicks? once the Converter is installed to the stator support and pump assembly it will be buried in the bellhousing and have to be slightly pulled closer to the flywheel once the transmission is installed. i hope this helps
Здравствуйте Сер ! Скажите пожалуйста! У меня проблема с АКПП, если утром выехал до конца непрогреом ДВС то АКПП падает в аварию 1передача 2передача и на 3 передаче остаётся ! Но если машину перезапустить то все хорошо и едит уже нормально. Может быть это связана с датчиками температуры АКПП А760 F ???🙏🙏🙏🙏🙏
My replacement engine had the round I think 6 hole plate that goes between the crank and converter already on it and I ended up putting my old one off of the blown engine on it too. I doubled up that spacer or whatever it is and that is what caused my problem. Caused me to crack the sump and completely pull the tranny again but it's been going strong ever since.

More than likely, you broke a one-way clutch/sprag; it's internal. Here's our website to look for ATRA shops nearest you.

@@atra-automatictransmission1300 definitely not tire size its the oem wheels and tire size. Thank you for the info!

Hi gay, do you know. My toyota 2011, hit 2-3 upshift, don't have codes. Greetings
Try getting it serviced. What's your mileage/Km? Maybe a programming issue?
hi. why is my SLU solenoid doesnt work? always off position. cant engage 4th n 5th gear? a750f transmission
Hi, I have the same problem. Have you found a solution?
