TRANS Not responding
 

HELLo ALL I'm a noob so any info will be greatly appriciated. My truck is a 2003 cummins 2500 4x4 the PROBLEM I'm having is when i shift into gear the trans goes in gear but the indicator is not showing anything (the circle around the gear its in) it does appear in P and N but not in R D321 but it does go in gear and the trans will not shift .What I have done to fix it so far is change fluid ,filter ,govenor pressure sensor and silenoid ,range selector switch on the trans and PCM . Is there any sepperate comp for the trans? THX in advance for any help!!!!!!!!!!!!:argh:

my 06 did that only it wouldnt do it for the park light up, worked in all other gears, i had to adjust the shift linkage, you could try that...

thx klickster I will check in to it .
