Voyager transmission problem

Your transmission need rebuilding. You can buy some TransX and pour it in your transmission. Make sure drive the car to help the TransX to work it way through the transmission then you should get shift reverse. If it does not work then your transmission is badly damage. So you will have to get it rebuild or buy a used one.

Could you please smell the transmission fluid sound like the clutches are burnt in the G/Box. If the oil i
has lost its red color and smells funny then you have a serious problem

The valve body is a part roughly the size of a 8 X 11 piece of paper, only about 4 inches thick.
It is made of aluminum, and is really filled with lots of holes and passageways.
It is up inside your transmission oil pan.
As you drive, transmission oil is supposed to circulate inside this, and change your gears as you drive down the road.
These do fail occasionally, and are expensive to replace, often costing 1,000 to 3,000 to change, as most shops will overhaul your whole transmission in the process.
If you will type in " Ebay motors", and then type in "Plymouth valve body", you can see a picture of one.
Be blessed.

Gears inside welded together, or stuck in limp home mode. Is it stuck in a gear other than 1st or reverse? Limp home mode will select one gear, usually 2nd, when computer senses a problem with valve body pressure, or excessive heat. Either way it sounds like a trip to the ****** shop.

the most common problem barring any internal issue is the input sensor. Should scan to get proper diag

your gearbox needs some oil

To make a long story short, your transmission is done. Sorry. I just went through this with my Voyeger.

Sounds like you need a solenoid pack to start, and possibly a service. If the tranny is not slipping, the solenoid pack is stuck and not tell it to shift up. Could possibly be a TCM, but not as likely.

I've had this happen before. It turned out to be the output sensor on the trans.

you say the fluid looks good... that's great.
now next time your out drive for about ten good minuetes long enough for the transmission to get nice and warm and then pull over to nice level ground and with the vehicle in park check the fluid again. it's kind of hard to read because it always has a lot of bubbles on it and stuff. but it may be low on fluid.. good-luck ray
