I am new to this so forgive me if I did this wrong, but I need help... In the last 5 days my dodge has started weird things. First the blinker went crazy then the next day the ABS and Brake lights came on the the day after that she started shifting slow from 1st to 2nd, then the next day the speedometer stopped working. So far I have replaced the speed sensor and found and replaced an oring. Oh yea and fixed the blinker.... bbut it is still not shifting right. I am a girl and am going by a book I have for my truck.. can someone pls help

 

Broke this out into it's own thread. Welcome to DF!

how's the battery? When is the last time fluid/filter in the trans was changed?

Could try disconnecting the battery for five minutes to reset the PCM, and see if it doesn't figure things out.

 

+1, any time you change/clean a sensor, disconnect the negative battery cable so the PCM can reset while you are doing the work.

 

Which speed sensor did you change (there are two of them)?

Did the ABS Brake light issue go away?

How is the trans fluid? Check in Neutral with truck warmed up. Does the fluid on the dip stick smell burned or look dark?

And just so you know, use only ATF+4 fluid in the transmission. Don't let some guy at auto parts store tell you something else is just as good.
