help!!!! just had trans rebuilt and still have problems. overdrive light still flashes and trans dosen't feel like it is locking up tranny place said to check tps switch did so and reset to 1.1 volt at closed throttel and 3.95volts at wot can any body give me ideas i'm about 7 hours from the shop that did the trans.

 

Go to Walmart or Autozone or whatever parts supply place is near to you. Get a 95 and earlier Ford code reader, should be about 30 bucks, has all the instructions for reading trouble codes, and what they mean, that will put you in the right direction for troubleshooting without taking out a 2nd loan on the house. Post back on what codes you get!

 

yes have codes read , also the throttle must be held at wide open when performing the key on engine off test
if you do not hold the throttle open during the test you will receive a false hard fault code for the fipl (tps)

 

If the OD light is flashing the torque converter cluch wont engage. you are in limp mode do not drive your truck in limp mode it will toast your trans very quickly. Dose your tach and speedo work? Do you have an ABS light on?

Did the trans rebuilders ever figure out why the light was on befor they rebuilt the trans?
Was the rebuild suposed to fix the light?

 

yes had shop help do diagnostic with there solorus computer and there showed no codes. don't know if I can say this but these guy's really whent out of there way to help me. but there not a diesel shop and not a true trans shop. now back to the truck yes the speedo and tach work fine no abs light and no codes on the computerand the over drive light still flashes

 

does the o/d light flash very quickly or is it a slow flash

 

by the way you said there were no codes
the system will always display codes either pass codes or problem codes
if it will not display any codes then the system is not testing
check all fuses there are two that affect the processor and the grounds are very important check the one that is bolted to teh fender nect to the DCL plug
