I have a 2006 is350 & was experiencing some transmission issues. I ended up replacing my transmission solenoids. Which fixed my issues, but gave me another issue. After replacing the solenoids, I now have "No Reverse". I can put the car in neutral & push the car backwards when car is off. But when car is on & I switch to Reverse Gear. Nothing happens, no other issues. Car runs like a champ. I tried replacing the solenoids a 2nd time. But still no reverse gear. Transmission fulid is good only I can think of doing next is testing the wiring in the transmission next. Anyone else had this issue? Or just me, lol... Any help would be appreciated.
