So lastnight I noticed that my car will not shift into 4th gear like I had over drive off. I to have a code for the speed sensor but that has been on for months. I can not figure out what it is.
I have sen checked the sensor with a lab scope and it all checks out good. Can you guys please help me out.

One last thing I have a bad exhaust leak would that have anything to do with my problem?

 

Was the car driven from a cold start as these transmissions will not shift into 4th (overdrive) until the transmission fluid has warmed to a certain temperature

 

Yea it was cold but I also drove it around toda and same thing. It's 63 here and I doublt the trans is Yo cold now

 

Pull the transmission codes to see if anything flags up as it could be any number of things like shift solenoids,transmission fluid temperature sender unit,wiring fault.
I take it the fluid level is correct and in good condition?

 

pulled the code and its #42 for the speed sensor. I have had this code for months now and no problems other than speedo not working some times. fluid looked good but decided i would do a drain and change the fluid and filter.

 

Still doing the same thing. I checked the shift solenoids and they seem to be working. Some one help please

 

Its not a sensor. Its a solenoid. Some are external, some are inside the valve body. What was the code?

 

thats the thing im not getting any trans code the only thing im getting is a code for speed sensor 1
