My buddy has a 01 cummins and the computer is tell the converter to lock and unlock when driving at a constaint speed, does anyone know what could be bad that is telling the computer to do this???
Thanks

 

Comprimised,

I believe what your buddy is experiencing is electrical noise. The TC will lock and unlock around a specfic speed and it gets annoying as hell. There are several write ups regarding this along with different approaches that people have used. From all the reading I have done and having this happen to me, I did the suncoast re-wire and it worked well. Check out this THREAD

SunCoast rewire ans an APPS adjust and rest would be the best place to start. Ver cost efficient!

 

i usually just move the alternator wires around and it fixes mine for several months. Sometimes I have to clean the battery grounds also.

 

Thanks guys we are going to try the suncoast re-wire.. I will let you know what happens

 

there are several different fixes for this and ive heard its not a one fix all issue. i hope the suncoast rewire works but if it doesnt work for ya to try the bd noise isolator. thats what i have and i like it.
