I have a pickup automatic transmission I put my code reader on and it said I have a transmission temparature sensor fault/out of range! could this make my truck shift hard, it did not shift hard at frist but one day it just started shifting hard! and can they stop the hard shifting without taking my transmission out?

Check "both" the speed sensors on the transmission. They will make it shift hard as they are designed to tell the computer how much hydraulic pressure to apply to the shifting so that the transmission will shift the same as new all through it's life. When it gets a crappy reading or no reading from one of them it assumes that the transmission is slipping and needs more hydraulic pressure. Particularly if this is an american pickup and especially GM This is also true of almost all cars with automatics as they are pretty much all electronically controlled nowday for mileage and emissions. The temperature sensor can cause a bit of this itself, but I have never seen that signal alone cause the shifts to get very hard. The temperature sensor gives the computer info though similar in scope as the temp adjusts the pressure to some degree as well. If you know that you have a bad reading on that sensor change or repair it first and clear that code out. If that does not fix it them change those speed sensors. One other note is that on GM in particular the wiring on the transmission plug where the big harness plugs into the trans with all the wiring for the internal sensors and solenoids can make a bad connection. This is a bigger problem on the early series with the round connector. Check that too if you continue to get readings on the computer.

Without the year, make, model, engine, or transmission type how can you expect to get an answer from a professional tech.
Did you know that if you run a scan test on some vehicles when they are cold and not at operating temperature you will get that code? A computer detected fault will put your transmission in a fail safe mode giving it high line pressure and firm shifts. Did you put a gauge on it? Time to bring it to a professional for proper diagnosis. If you take the advise of getting your transmission flushed at least your decision will be made for you when it starts slipping a couple of weeks later.

You failed to mention the Year make and model of the truck. It's possible that the sensor could be the cause, however it's more likely you have contaminated tranny fluid. both of these can be resolved with out removing the transmission from the truck. both should be about the same cost. have the shop do a complete transmission flush (not a pan drop and refill) and replace the sensor. if your transmission overheated it likely burned the transmission fluid and would need to be flushed and new clean fluid put in.

got fluid in it?. Go to the shop quick. it may be something small that will only get worse.

replace the sensor or check the vacuum line to your tranny ...
