Re: 140h transmission failure

You need two things, need to hook ET to it and see what the fuatl codes are and hook a guage up and check the trans pressure, see if you have any. They are kind complex transmissions, could be clutch, input shaft, ECM, lots of things.  Also check the fuses and see if they are all good.

Re: 140h transmission failure

this has a power shift trans correct?if  it is no electrically you have a valve body pressure problem.of memeory serves me correctly there are tubes that flow through the body and these tubes well they dont fall out but they will leak.means they wont have enough pressure to kick the nuetral safety,and that has to be on the money
