I have an auto g20 with recently swapped sr20de, original engine crapped out at 230K. Bought the car with 168K on it and the trans went out like 20K later after I downshifted to 2nd and hit the OD button LOL. Purchased an SE-R auto trans from WES on here and had to pull it apart because some parts were different between B14 and P10 chassis but it has worked great. I thought it was fucked up at one point because it was chirping tires from 1st to 2nd it shifted so hard but after tracing the resistance on the valve body to the control unit I was able to find out that the dropping resistor was all that was bad. All in all I have been happy with mine other than the fact that the auto's shift too fucking early and are fucking dogs compared to the 5-speed.
