After changing rear end ratio on my FLD120 from 3.58 to 4.63 the speedo isnt working correctly .Anyone knows what need to be done for correct speed to be displayed ? KRiS
Your going to have to change the speedo gear at the transmission output shaft. A Freightliner dealer should be able to provide the parts for you, or you could search on the internet for someone who rebuilds trannys, they might be able to send you the parts as well.
thnks for info !
