Shifting / Rev limit problems.
After some hots laps in 4lo and 4hi, I noticed that the tranny shifts perfect in 4hi.
In 4lo the tranny will hold 1st until 4500 RPM and sometimes beyond (rev limit)
I looked through my wiring diagrams and found that the NP241C has a ball switch that shorts to ground when the case is in low range. This signal is sent to the PCM to to tell the tranny it has adjusted shift points.
I also think my fuel pump is failing.
It was NEW...
