It's not shifting into neutral, the 3rd gear "drive" band is slipping. Time for rebuild.
The 700R4 is electronic, and has over drive. The 400 has a detent cable that shifts it, and no over drive.
They did not use a 700R4 in 2000 model. It would be a 4L60E.
th 400 th 350 if it has over drive 700r4
It may be low on fluid. If not then the bands inside the transmission are bad or gone.
Any unnecessary shifts cause additional wear on the shift mechanism, but that's a minor consideration. At a long signal light or train crossing, it's better for the transmission to shift into neutral than to keep it in drive with foot on the brake, or if a manual, better in neutral than holding in the clutch all that time.
My f150 shifts from 2wheel to 4wheel on the fly, but to use 4low you need to be stopped with your transmission in neutral to engage the low range in my transfer case.
Well, if it's a Chevy truck, usually a 700R4 will be the type of transmission put in a 1992. Or a 4L60E. - Aaron
Yes but you may have to shorten the drive shaft if it is a 350 turbo going to a non electronic 700r4
The wiring for the early 700R4 controlled the lock up converter only. We used to ground the wire by passing the external vacuum control so as soon as the transmission went into over drive it would lock and stay locked to prevent transmission overheating.
my automatic transmission is stuck in neutral. how do you get it into gear
you have burnt out the 3rd. gear and overdrive. you will have to have it rebuilt or replaced.
if you feel or hear it engage when put in reverse but will not move or even roll down the drive way. But rolls fine in neutral. a clutch pack is engaged that should not be.
