Hey guys my 2001 dually with an automatic is giving me fits. The transmission does not slip it just shifts back and forth when driving at slow speeds. OD off and it still does it. Any ideas? is there a sensor or chip that i can replace or change to stop this? thanks, Jt:banghead:

What speed exactly? Is it shifting or going in and out of lockup? The later being a very common issue. You might have a bad apps sensor as well. I would try resetting the apps sensor and see if that fixes the problem.

I just got done replacing the gov sol & pressure sensor in my 04 48RE this weekend. I was experiencing the same thing you are having. Ordered the parts from DTT.COM but it should be noted that, before you install the gov sol you MUST make sure you install it using the correct grove!!! If you are going to do the install let me know and I will tell you what to look for.DON
