2002 Toyota 4Runner SR5 or Tacoma V6 Code P0770( shift solenoid "E" malfunction)

 This under the Toyota Powertrain warranty is in effect for 96 months or 80,000 miles. The ECM(PCM) needs to recablibrate.When you saw this code the first thing you should do is take it back to the dealer.   But if you out of warranty what you can do is remove the glove compartment door. when you see the ECM  is the second connector from Left to the Right hand side( E10) 22 wire color( wht/red) and 23 (yel/red) and check the ECM terminals SP2+ and SP2- measure the resistance. It should be 560 to 680 ohms, if resistance is as specified the ECM need to replace. Speed sensor from transmission it needs to be check out too.  Resistance should be 560 to 680 ohms. what I found is the resistance at termianls sp2+ and sp2- are 6790 ohms.
