TRNW TECH TIP
OF THE MONTH!
Compensation codes must be reset on late model Toyota's!
Compensation Codes from the transmission must be inputted into the ECU for proper calibration!
Toyota Techstream (click to enlarge)

U660 ECU or Trans Replacement!
Compensation codes are codes that are entered into the programming of U660's and a couple other units that are based on where the transmission was manufactured. If the unit is changed, the PCM is changed and probably the pump and a couple other hard parts are changed (not proven yet that I know of) the compensation codes need to be changed so that the programming matches the unit. The computer uses these codes to determine the correct pressure control and other control curves to use. The resets are not based on the compensation codes and resetting or clearing the adaptives don't alter the compensation codes. I attached a pdf that contains screenshots using Toyota Techstream and a J2534 box that basically shows the steps to do both and what it looks like on the screen. - more

    new feature!INTERACTIVE TECH TIPS & TECH DATA

    TRNW has just introduced a new feature to their website which allows technicians to add rebuilder tips, picture tips, and technical data for every transmission model. Members can vote on each rebuilder tip or picture tip with the results determining the placement of the tip. There is also an option for adding a comment to each rebuilder tip, and error control is built into the whole package allowing members to delete any tip that they created.

    Technical Data such as application charts, checkball locations, torque specifications, etc can now be added to the website by the members, and rebuilder "cheat sheets" can be printed out for technicians to take to the bench. A cheat sheet can be created, edited, and saved by each member by selecting from the list of current rebuilder tips, picture tips, and technical data for the desired transmission. The output is formatted nicely for printing.
