Was told, "no codes so it must be the tranny." OK'd the work. Changed out the transmission and I still have no Overdrive! Had they just done what I asked, I'd be on the road and NOT out $650. Can anyone tell me which ECU (s) will work for the 2JZGE on the '93 SC 300? Your help is greatly appreciated. Oh, and maybe a REPUTABLE mechanic in the South Florida area?
Just called Lexus and was told $875 for the replacement plus a core rebuild charge.
