Traction control? Are you talking about the atrac system in 2nd gen tacomas that acts like an LSD. Quite positive my 1st gen tundra has a true LSD...
Are you sure it's factory and wasn't added after the fact? From most things I've read, they never came with a true LSD. I could be wrong. The easy way to test is is to jack up the rear of the truck. Put it in neutral and spin the tires. If they spin the same direction then it's a LSD. If it's opposite it's open and uses trac control.
Well I think I'm wrong. I guess it was an option on the 1st gen trucks. I apologize.
