ok.replaced the gov solenoid with a borg and changed pressure sensor. took valve body off and cleaned.had a broken 3-4 accumulator spring replaced with sonax spring.got it all together and still wont shift to 1st unless I go to n first then down to 1st and still no od.when I first tried it it would down shift from 3rd to 2nd at wot but now it wont.drove around about 5 miles.still no cel except for the o2 sensor.what could it be now?

 

TV cable properly adjusted?

Getting good contact on all the pins on the trans connector?

Connectors at PCM clean and tight?

Shift linkage properly adjusted?

That's really kinda strange behavior without kicking out a code.... Did you reset the PCM after changing parts??

 

the battery been disconnected for a few days.ill try adjusting the tv cable again.how do I properly adjust the shift linkage?

 

Procedure is in the factory service manual.

 

drove it around the block this morning and put it in drive and started in first but skipped 2nd.no od.stopped several times and started off in 1st every time.put it in reverse to turn around and started in 3rd again.I broke the plastic on the tv cable so it wasn't connected and got a p1757.I clear the code and dont come back untill I let it sit over night.could this be due the valve body or pressure sensor.

 

Unplug the 8 pin connector on the drivers side of the trans, 'bout halfway back. Go for a ride. Keep in mind your trans will have ZERO automatic function. (no o/d or tcc either) If the trans shifts into the gear you tell it to, when you tell it to, replace governor pressure sensor/solenoid. (both)

If it doesn't, time for rebuild.

 

im now getting the code for the pressure sensor. ill be buying a new one.

 

but ill unplug it and see

 

Replace them BOTH while you are in there. Otherwise, you may find that you had more than one problem, and have to go back in. Get the heavy duty borg warner governor solenoid. You can find sets on EBay for 100 bucks or so.

 

I already replaced the solenoid with a borg and a used sensor
