    Probably clutch packs. Pull your trans and contact FLT, they'll take care of you

    You could but unless you know what you're doing, you'd be better off having it professionally rebuilt. I watched a 4L60 get ripped apart and they are very complex.

    Any Check Engine Lights?

    If you have not experienced any slipping, then the solenoids could have crapped. But the chance of the 1-2 and 2-3 solenoids going at the same time are slim to none. The solenoids are pretty damn good.

    Is your tranny fluid good? Low? Smell burned? Any chance this happened after going offroad or in mud?

    sounds like you lost voltage to the transmission. Pull the large connector off the passenger side and there is a lead in there that should have 12v going to it. Test it with a test light to verify. I believe it has 12v even with the key off but you may test it both off and on, just don't have anyone with their foot on the brake when testing. Braking kills the 12v source.

    210,000 miles could be the problem...lol j/k

    how sloppy was the mud, is it possible that you got some water in the trans via vent hole, or how long was it burried before you got pulled out?

    did you try rocking it out? maybe spun the trans at too high of rpm's and the 210,000 miles finally caught up with it?

    im with tyler, if the fluid looks good then it maybe a solenoid, i think if you have no 2-3 its solenoid B....but its been awhile since i have had a trans apart.
