Hi there,

I have a 2002 Escort SOHC with an '01 engine(factory). Recently the tranny started having a delayed shift problem from 3-4 on the highway. As soon as I let off the gas just a bit it will shift. Can this possibly be a vacuum leak prob? What controls the shifting in these cars anyway, the ECM or is it vacuum modulated? Thanks!

it's electronic, not vacuum. could be a shift solenoid, could be gunk in the valve body. when was the last time the fluid was replaced?

Same thing with my car.....is it worse on hills? On-ramps to the expressway? Sometimes instead of taking my foot off the accelerator, I keep it there just to see how long it will refuse to shift....probably not a good thing....the engine just yells back louder.

like your situation, it won't shift unless I take my foot off the accelerator ....or until it gets to the top of a hill.

I'll be watching this post....

I've only noticed it on the highway. Guess I havent played attention on hills. Are you willing to pay 30 bucks to learn how to fix it the hard way? I signed up to this website called eautorepair.net. It's $30 a YEAR and it's pretty much a factory manual. I'm not a rep for them or anything, but I just got it and I'm going to try and do some of the tests they recommend. This weekend Im going to try the torque converter engagement test, then the TFT sensor, then the TSS sensor, then do a transaxle drive cycle test. That's what they recommend. You test in that order until you find which is bad. I think you need a code reader when you do those tests though. Im going to try all that this weekend. You should check it out and maybe we can fix this problem together. good luck!
