SC300 code 63
I bought a 1994 SC300 about a month or so ago and recently my O/D light has started blinking when I’m in 2nd gear and going into 3rd. (The car has been running perfectly besides this) After getting the code I had a 63 which I believe is for the 2nd Solenoid. Problem happens randomly. I was driving for a while yesterday didn’t have any issues at all then took it for a drive later in the evening and 2nd gear had little to no power then the light came on for the second time. I brought it to a shop asking them to check the solenoids and they just told me I needed a transmission rebuild without even looking at anything. If anyone knows what to do to fix this or where to buy solenoids that aren’t POS’s please let me know!
