01 5.9 auto 142,000 miles. Truck started going to 3000 before it would upshift from 1st to 2nd then to about 3500 before it would shift again. Changed out the selenoid to a borg and pressure sensor. This didnt help anything. The pan magnet was very clean. Didnt see any loose connections. The truck is throwing no codes. Did I overlook something? Check fluid level and its good. This just started all of a sudden. Any help would, I would be thankful. I am thinking rebuild time. one more thing when its around 45mpg after the shift it gets real eratic. This is even with OD turned off or on. I also checked the cable at throttle body and its good. Thanks.

 

did you just change the solenoid? Or did you change the pressure sensor as well?

 

i changed both. I got them off ebay from electrical advantage. I wonder if I installed them wrong

 

I'm not sure it's possible to install them wrong.

You might check the TV Cable, it may need adjustment.

I will check TV adjustment tomorrow.Thanks

 

Recheck fluid level as well. (in neutral) Take a look at the connectors on the PCM too, they like to corrode, and then strange things start happening. (disconnect battery first. )

 

done all that this morning. still same. I am wondering if that china made pressure sensor could be bad.I am fixing to put old one back in.

 

does the truck act differently with new pressure sensor or is it the exact same as the original. if same as the original, then its unlikely that its bad.

 

acts the same. I have been reading that some of them china parts have been known to be bad out of the box. I cant find anything else wrong. I have checked all the above. Guess I am just shooting in the dark here.2

 

Band adjustment?

Could just be the beginning of transmission failure
