I have a 1982 Toyota Supra Engine Control Unit(ECU) that was pulled from a RUNNING Supra that had an AUTOMATIC TRANSMISSION. It had the I6 DOHC 5M-GE engine. It is in XLNT Condition and was working perfect prior to removal-[engine was running great]. Be sure the p/n on your old unit matches the p/n on this unit to insure proper fit and function.
