[buffulax]

Ok, I start with the Error Codes. I can't remember the exact error code numbers, but I remember the descriptions

First, Switch signal. What is it and how do I fix it.

Second, Starter signal. What is it and how do I fix it.

Third, Speed sensor. I do not have the speedometer cable hooked up, so I assume this is the problem

Tranny issues

At any speed in any gear, when I let off on the gas and then give it gas I feel a clunk in the tranny. It is not the Universal joints because I felt them and they are tight still. possible tranny or rear end?

one last issue

My CV joint boot is ripped how do you replace them?
