IS200 Throttle Body Mod

[Mattybuzz]

Hi lady's and gents. I've recently purchased a nice little IS200 and love the car except for the mind numbing performance. 

I was informed of the "throttle body mod" but I can find much info on anybody doing one on an auto. 

I completed the mod yesterday arvo and was going to eventually measure the resistance across the electronic motor and use resistors to fix the light. 

However the trans seems to be in some kind of "limp mode" and will not kick down when hard accelerating. 

Has anybody come across this issue and com up with a solution??? 

Please help..... soooo slooooowwww
