You need to have a real good scanner connected to this. The onboard computer diagnosis will sometimes store intermittent Codes but needs to lock a Code for cheaper scanners to read.

You will save money by using the right equipment and buying only the parts you need.

At 55MPH you are way past Torque Converter lock-up speeds. Could be speed sensor not giving accurate info to PCM.

The Transmission shifts very hard after the first shift. Check engine light is on as well as the Green overdrive light blinks off and on. Speed sensor was cleaned and even replaced.


Your on the right track. Have you scanned the PCM, what codes did you get? If not and you changed the vehicle speed sensor,(VSS) did you check the (OSS) output shaft speed sensor, it will cause torque converter lock up and hard shifting and that pesky OD light flashing. I have also found that clutch packs inside auto tranny's dry out. Ford and some aftermarket companies sell a fluid that will recondition the clutch packs.

You need to get the engine trouble codes by performing the "keydance" or using a code reader, then start checking fuel pressure at pump and regulator. Best luck. Amclaussen.

Shift into D the N started flashing green .


Try moving the shift lever from D towards the next gear away from N (not all the way, just hold it a little bit over). If the N light goes out and the D light acts normal, then your shift linkage needs to be adjusted so the transmission goes into gear exactly when the shift lever is in a detent.
If that isn't the problem, it's time to get a readout of the engine error code to see where the problem is. You can get this done at most car parts stores, or they may let you use their engine code analyzer yourself if you give them a deposit on it. (The two hardest parts are getting down under the steering wheel to plug it in and deciphering the error code.)

My 2000 Saturn did not pass inspection due to evap. and O2 sensors "Not Ready". How can I fix the problem or how can the problem be fixed?


What is the EVAP code?

The O2 are not ready because it takes some time for them to complete there self check after clearing trouble codes. This will involve a few drive cycles. Once the evap problem has been resoled, the check engine light cleared, you'll have to drive it for a couple of days to get everything in the "ready" status.

Do you get a check-engine light, or does the transmission O/D light flash? Many times, this is due to a speed sensor on the transmission. When the sensor goes, the transmission has to do default shift timing and it will shift very late. Usually, this will set a code in the onboard computer.
