TC seems like locking /unlocking
 

Hi all,
I have a problem;
My truck has started what seems like the TC locking/unlocking. This happens when there is a lug (1200-1500 rpm). Mainly happens in 3rd gear I think after shifting from 2nd when RPM's are relatively low. Once RPM's are higher it doesn't seem to do it, but will also do it in 4th.

I did adjust the front bands to 80 in/lb in July but it did not start doing this until about 1 month after that.

Any ideas on what to do?

Thanks!

does it only do it around 45 mph?

It does it at any speed where the rpms are under 1500 and there is a little load on the engine.

Mine does it around 45 so I just do 50

Any ideas on this?
Thanks,

DTT Noise Filter will fix this issue. Its caused by an electrical noise in the system. Its causing your TC to lock and unlock.

Luke,

but why would it start all of a sudden?

Thanks,

I had my 01 for over 5 months before it started doing it. I unhooked the batteries and it would quit for about 2 days then start back.

I'll have to do that. I'll update what happens.
Thanks!

Yeah i think the DTT noise filter is kinda like the BD Diesel Apps noise isolator
