As an update: More odd behavior noticed- getting stuck in third for instance. While that could still happen if the governor pressure control is out of control, we found part of what we assume is the OD snap ring in the pan. Whether that is the right snap ring or not I'm guessing there could be...

Ah. Good to know. All of this is helpful. This is certainly a high mileage, original transmission and may very well be on borrowed time. He doesn’t haul anything with it anymore because he’s in bad health. I’m just trying to nail down what is going on for him. Everyone else is just going to...

But to your point about old-school techniques- if I tap and measure the gov signal, will it be directly proportional to vehicle speed, or does the ECU just discrete step across the pressures at which the valve body would switch in a fully mechanical transmission?

Thank you for the suggestion. I don't recall the speedo dipping, but I will have to specifically watch for that. Is the output shaft speed the source for the vehicle speed in the instrument panel? In other words- can I assume that if the speedometer reading remains plausible during a delayed...

Thank you for the welcome. This would be a 48RE in an '04 if I am not terribly mistaken. I guess that is the heart of my question- what tools are out there? I don't need to tweak, tune, or flash anything. I am just looking for something to be able to see some of the operating parameters of the...

Hello, First time poster- thanks to all you guys who answer questions and build out a reference for all the owners out there. I have a question about troubleshooting auto trans shift issues. My father has an '04 DR 5.9 automatic that I work on for him when needed. I have replaced the pressure...
