I have been struggling with a jerking transmission when my 95 LS400 is up to speed and I take my foot on and off the accelerator. I had the dealership check the trans - said it was fine and saw no codes. Their thought was to first replace the plugs then the throttle position sensor and if all else failed the ECM. I replaced the plugs and am now at the TPS. DOes anyone have a procedure to adjust it as well as the correct voltages you should find?
THANKS
