Question about Cars & Trucks
I have a 99 Plymouth voyager van and when you go to start moving the rpm go up really high than when you get going it will be fine and then it will **** back than go again just fine so i took it to the parts store and they scanned it and the codes that came up were p0731 p0732 p0736 p0700 and i was wondering what i can do to fix it
Probably not much you can do yourself.
Code 700 is a general fault code for the transmission or control module. Code 731 is for incorrect ratio for first gear, 732 is for 2nd gear, and 736 is for reverse. The actual problem could be mechanical or electrical, including the transmission control module.
You would need a shop manual and the necessary tools to check the circuits and solenoids inside the transmission.

speed sensor most likely this transmission runs 2 an input and an output. if your speedometer is fluctuating or not working it would be output problem if not probably an input speed sensor. these sensors can be purchased for around 40$ i believe at your local dodge/chrysler dealer.
replacement is fairly easy. open hood remove air cleaner locate the sensor on the transmission. in put is closet to engine. unplug sensor remove by unscrewing it. reverse for installation. disconnect battery for 2 min to clear codes and road test

all the codes listed above are saying incorrect ratio for each gear,you should take this to a dealer he can determine which faulty sensor on the transmission is causing this,it is not a internal transmission problem

It sounds like a blown transmission to me.I would go to an AAA approved shop.I have seen VERY disappointing results from friends,family,and myself when getting it rebuilt or a used one.Replacing with a new one if there isn't a warranty may cost a few hundred dollars more but it will most likely have a 1 year warranty whereas the other 2 choices have nothing.A new one will last much longer too.I had a transmission rebuilt which failed within the first year.Ever since that,I have driven a manual transmission because a clutch is easily at least 3 times less to replace.I had one about 9 years ago for $500 USD.Good luck,Greg

Check your transmission output shaft speed sensor. First check that the connector is clean, free of corrosion, secured firmly and that wires have good insulation. If all looks well at this point then disconnect the speed sensor, remove it and clean its tip of any debris and see if this clears the DTC. If not change the sensor for a new one (less than $30). This should fix it.
