cummins 47re transmission

[bimsbuell]

Hi ,Just wondered if anyone could give me advice on my transmission. The story so far is that I only use this truck for a couple of months each year in the summer so have been putting up with what I was hoping was a "getting worn" trans.It seemed to slip a bit especially in second but once in fourth seemed ok especially when the converter locked up.Today it went WRONG.... Just started to coast down a hill around 50 mph when I lost O/D It still drives fine in 1,2,&3 but no O/D.I put a code reader on it which read Governor  Low Pressure but I had no CHECK ENG light  Could it just be the o/d solonoid or sensor??and whats the easiest way to check them Any ideas what to do next or can anyone sugest a good transmission guy in NE Pa.

While more than likely it's the governor solenoid and sensor, what year is the truck and how many miles are on it? This is will tell us if you're in the realm of a quick easy fix or the you're better off getting it freshened fix.

Without testing the governor pressure (port is on the passenger side of the trans and is the last port before the OD section). The governor pressure is what will tell you the real problem.
