I have a 1998 Town & Country that was converted to a wheelchair accessible van (electric side entry ramp, etc. etc.). Recently I had trouble putting it in parking and took it to my neighborhood garage where they replaced the shifting cable; it works but still have some play on it.

Itook it to a car shop where they diagnosed via a computer "P1788 Mod 41". what does that mean?

 

P1788-2-4 HYDRAULIC PRESSURE SWITCH CIRCUIT

most of the time its a solneoid pack assembly.
Could have wire issue as well.

 

What does it mean? Translate please!
Is it difficult to repair?
Should I be lookig for another van?
