I have a 2002 Ford Focus with the 2.0l DOHC engine and automatic transmission, 153,000 miles. The issue I’m having is that there seems to be a serious delay in how fast the transmission upshifts during acceleration; if I try to accelerate at a normal rate, the RPM goes way up for a few seconds before the transmission finally shifts to the proper gear, and it usually does this 3-4 separate times from 0-35 mph (I haven’t noticed the issue much above this speed). Nothing odd happens during deceleration, and there seems to be no other issues once I am cruising at a given speed. If I accelerate slow enough (and I mean a crawl) this issue doesn’t happen, or happens less. I do have the error code P0705 (Transmission Range Sensor Circuit Malfunction), and I did replace this sensor, although I couldn’t seem to get it 100% properly adjusted despite having the 307415 tool (there is a small chance this is the issue?) Shift solenoids A-F, trans fluid and filter, and temperature sensor have been replaced since the issue started, and the fluid is at the proper level and is the proper type. I did use Super Tech fluid, though. I also recently pulled off and cleaned the throttle body and replaced the throttle position sensor with a new ford genuine sensor. Any ideas?
