It is a well documented issue that I discovered the TSB for please check that thread out and get the latest TCM logic flashed.

thanks for help, but my frs is already install the turbo kits and reflashed the ECU, is that still possible to go to dealer fix the TCM reflash?

Do you know someone with the techstream? I have the cuw file for you to flash if you need it.

i can try to go tuning store, or it has to be a dealer to flash it?

A dealer will have to flash it honestly, you may have to pay for it because you have a turbo. Also important note, if you have an ecutek tune there's no way in hell your ecu can be flashed by techstream. That's becaue your ecu is locked after a flash to prevent tampering of the tune. You really should go to wherever you got the tune done and ask them if they have access to techstream to flash the latest tcm logic.

thanks again, can you give me the file? i will give to my tunner and let them find a way to take care it

Here you go:

But honestly only toyota techstreams calibration update wizard can open that file. If that doesn't fix the rev match issue then the turbos constant boost must've worn something out in the trans, but the dynamic rev matching being the only issue really comes across as a tcm issue

hey buddy, i went to dealer, they can not help me flash that, did you know somewhere or some tuner can help me do that in los angeles area? thanks man~

You'd have to flash to stock somehow and then beg your dealer to flash it through techstream the proper way, which will be nearly impossible for you because of the turbo kit.

ecutek only locks you out of the engine ECU.


maybe the dealer doesn't realise it a transmission control unit update, not engine ECU.

im agree with u, i will try to find a dealer can help me update, thanks man

Do you have it in sports mode when driving in manual? I've found it to be smoother when sports mode isn't on. Matter of fact, the car feels better when it's not in sport mode/vsc imo.

Sport does not effect throttle mapping regardless, and also doesn't effect shifting when in manual mode....
