Install Guide - U151E, U151F & U250E - Toyota (Automatic Transmission)

YOUR WARRANTY DEPENDS ON YOUR ADHERENCE TO THESE GUIDELINES

IMPORTANT

Failure to verify a properly functioning ECM is installed in the vehicle will cause immediate transmission damage and will void your warranty.

CHECKLIST

  • Scan original vehicle computer, record any codes for later review, and resolve all codes. Please note that some engine codes will prevent shifting into 5th gear in this application.
  • Inspect all engine mounts, transmission mounts, and cradle mounts for wear and damage.
  • Inspect drive axle splines, retaining clips, and CV joints for wear and damage.
  • Test all sensors and switches that have been transferred from the original transmission for correct operation.
  • Compare replacement transmission and torque convertor to original before installation.
  • Transmission cooler and lines must be hot flushed or replaced.
  • Inspect flex plate closely and completely for any cracks or damage.
  • Verify that the engine block and bell housing surfaces are clean and free of paint, grease, oil, dirt, and corrosion.
  • Be sure both dowel pins are clean, in good condition, and installed properly.
  • Seat the torque converter completely onto the input shaft prior to installing the transmission in the vehicle.
  • On AWD applications, install the new transfer case lube passage seal that has been supplied.
  • Air tools should NOT be used to force the transmission against the engine block; this may damage or break the transmission case.
  • Fill the transmission with supplied synthetic or T-IV transmission fluid.
  • Confirm that the transmission has a good ground connection; reattach all ground straps to the correct location free of paint, grease, oil, dirt, and corrosion.
  • Do not use power tools to tighten the manual lever retaining nut. The use of power tools can damage the internal linkage.
  • Complete the Adaptive Memory Reset procedure for the ECM by using a capable scan tool. Disconnecting the battery is not sufficient to clear the adaptive memory. See next page for adaptive memory reset screenshots from a Toyota factory scan tool.
