Last summer I picked up a "low mileage" Jdm 4cyl auto trans for $450 and installed myself. I was a bit skeptical at first. But I was very pleased at how nicely it shifts. After one year, no issues. There were two sensors on the back of transmission that were 3 pins vs the 2 pin on USDM trans. I just switched the sensors over. Best $450 Ive ever spent. Knock on wood.
