just bought 96 ES300. Tranny seemed hesitant to switch from 1st to 2nd so I flushed tranny and replaced filter. A week later am a red light and accelerate on green and nothing rpm are up and no movement. so turn off the car put it in park and turn it back on and it reset it self and was fine till later on in the day. Now i cant get it around the block with out pushing it back. Changed a few sensors on top of tranny one of them a speed sensor. Did nothing as assumed, have a friend that works on cars and he thinks its the shift solenoid. Does this sound right? If so where is this shift solenoid located? And should i replace anything else? plz somebody help asap I need my car back
