[Pepin]

I o ready change the neutral safety switch and still the same... can some one tells me what else can I do? Thanks for your help

Have you tried manually shifting the trans to 2nd gear? Does the speedometer work?

I tried o ready to do it manually and still stays stuck in first gear... speedometer works and rpms works too

Did you both check the fluid level and check for transmission codes in the PCM?

 

[Pepin]

Fluid level is ok... no check engine light on... haven't check for a tranny code... I'll see if the computer that I have can do that

The PCM controls the shifting based on vehicle speed, throttle input and engine load. If the output shaft speed sensor went bad then the trans wouldn't shift and your speedo wouldn't work. You would still be able to manually shift to second from first in the manual shift positions though since that would be with the manual valve in the valve body and not the solenoids.

Are you sure you aren't in 2nd gear which I think would be fail safe mode?
