Supra Ecosse Posted February 3, 2011 Share Posted February 3, 2011 hi there, is anyone using a powertrain control solution controller on a lexus 5 or 6 speed box, i want to fit a lexus tranny to my supra TT and know the engine was shared with a lexus model sold in the US.However i am having trouble finding anyone who has moved away from the standard 4 speed of the supra. The JZA80 engine went into a lot of lexus models so i am hoping someone has already had the same idea. Quote Link to comment Share on other sites More sharing options...
ruffsls Posted February 18, 2011 Share Posted February 18, 2011 Help,help guys. I have a 93 LS400 w 292K on it. It runs excellent for a couple of hundred miles and then all of a sudden it starts to jerking as if somoene is turning the switch on and off very quickly.The jerking is very harsh,and you have very little power.When you attempt to pull off from a stop it appears that your transmission is slipping.If you shift to low range you get more torque but as speed increases and you switch back to drive youre very sluggish again. Ive also heard whats sounds like its backfiring in the intake occasionally.If you allow it to cool off or park it overnight the next morning youre up and running as if nothing occured.Already have done full tune up(incl coils),fuel filter and strainer.It is running and smelling very rich,and only DTC is 71(EGR).Replace it but didnt clear issue.Mileage is good until the "limp mode" occurs and then it takes 1/4 tank to get back home while only several miles away.Any help is greatly appreciated Quote Link to comment Share on other sites More sharing options...
