I am reposting this question because it's getting more serious and I need to find out what's wrong with my car. It is a 1991 Legacy with 2.2L AWD with non-turbo engine.
Here is the problem: As soon as the engine reaches operating temperature, it has shifting problem going 1st to 2nd gear. From a stop and go situation, I have to rev the engine up to 3,500-4,000 RPM before it shifts. Also, the speed has to reach 20 MPH before shifting occurs. This is based on moderate to mild (or vice versa) acceleration. If I press the pedal very soft and let the vehicle reaches 20 MPH very slowly, it shifts fine. But in traffic situation, I just don't want the person behind honking his horn because I just couldn't keep up with the traffic ahead of me.
From driving the vehicle and making a wild guess, I think it has something to do with the speed and/or speed cable not being registered correctly with the CPU. This car has never been involved in any racing activity or wreckless driving. It just started having this weird behavior beginning this summer '03. I don't remember having this problem in the past prior to this summer.
Once speed is above 20 MPH, no problem with shifting and there is no problem with 2nd gear up. Someone has suggested resetting the CPU or ECU (whatever) on my other posted (on the former forum) but I can't find fuse 16 as stated.
I hope I make sense here as I am really in need of finding out what's wrong (if anything at all). My hope is that it is not as serious or bad as I think it is.
Thanks in advance!
