Hello, I have a 2001 Ford focus that I had code p0771 and p0720, I have replaced the speed sensor and drained the fluid and put a new filter in. I have reset the codes as well. The car seems to not have 1st gear. I think it's wanting to start in 3rd gear. Is this disk slippage? Or can replacing the shift selonoid e fix the issue. Since I reset the computer it hasn't thrown any new codes though I only driven it around the block. The car seems to drive fine when I'm going 30 - 40 mph. Would Lucas transmission oil repair this? Any help would be appreciated. I was just on here a few weeks ago trying to troubleshoot a no crank no start and it seems like I'm losing the battle with the car as I had to replace the alternator previous to this problem as well. Thanks in advance.
