I have a 1997 Blazer. It started to fail to return to the 1st shift after fully stop or low speed. I had to turn off the engine to get it back to 1st shift. I have repleced the four transmision solenoid and after 3 month it failed again to return to the 1st shift. I parked the car for 2 month and after that the problem was gone but it came back in month and a half later. I parked back for other month and it run fine and suddenly start the problem again. the transmission does not go back to the 1st shift when fully stopped. today it did it but it started to work good alone and then did it again and then problem gone alone.
Can any one help me? does someone has an idea of what can be causing that and how to fix it?
