Lost all gears.

[JWiegel]

I was driving my 2000 3500 47RE this morning and it was falling into gear very slowly, almost slipping. A few weeks ago, I had a trans temp light coming on and falling out of O/D. On the highway I was running about 65-70 mph and started slipping, then lost all gears. Trans temperature never climbed over 150°F. There's 210,000 miles on it. On the scanner, all the solenoids are maxed out in voltage. It doesn't change through any gear selection. I pulled the transmission relay and had no gears at all.

It's had regular fluid changes, I change the fluid at every 15k miles. It does tow a trailer normally, only about a 7k lbs trailer. Debating, new transmission or try the governor solenoids. Any help would be appreciated.

What does the fluid look like now?

Do the easy first....please check your transfer case selector position.

Transfer case is in gear.
Fluid doesn't smell burnt, but does look a little black, can still tell its trans fluid, I did change back in April/ May. Trans temp light was coming on and falling out of O/D about a month ago. Then stopped. Was going to change the gov solenoids. Also had a crank sensor set a mil. Replaced it. They both happened within weeks of each other. I had C/S on hand, replaced it. Never really thought about the trans, it stopped acting up.

Might get more help in the 2nd Gen forum.
