TotoCh613

Found the problem, (code 4-2)with my speedometer not working and low power. After a clutch and transmission installment. When they changed the transmission, someone plugged the female conector from speed sensor (on the back of the transmission)into a wrong male plug wire.....it fitted perfectly ! Got under the truck and found a hanging wire near the back of the transmission unplugged the speed sensor from that connector and plugged back to this other one BAM ! It works now.... Thanks guys ,this is a great forum.

Hi there. Im also new to this forum, Im having a similar situation after a shop installed a rebuilt transmission and clutch, its a mack ch613 1997 427hp, my speedometer is not working NOW and I don't have any power!!, electronic malfunction light is on and code is 4-2. I bought a new speed sensor, installed it and checked the tone ring last night and nothing still have the same problem... I wonder if you guys can give me some ideas on what could it be. Thanks!
