I swaped a soarer 1jz non vvti auto into my 98 sc300. Everything is working except I can't get into overdrive. It shift through 1st 2nd and 3rd fine. I'm not sure if its because I have a gated shifter or what. Also I have been havering trouble getting the idle above 500 rpm even with set screw all the way out. I swaped the iacv but no change. Also the temp gauge pegs all the way hot. Any help would be much appreciated. I'm even willing to pay someone for there help. Thanks.

 

temp gauge needs a resistor to work.
