[QUOTE="mandkole, post: 1264848, member: 4630"] Sorry, its happened to you too.. Unless its throwing electrical codes for a bad circuit or bad solenoid pack, the TCC is likely slipping-- just went through this, spent a lot of time studying it, and have couple of threads on it. Mine had been slipping for awhile before it started to act that way. Others with BTS/PI combos have had similar issues. The converter locks, then as soon as you apply a little load, it senses excessive speed differential between input and output (slippage), then it unlocks. Once unlocked, it wants to relock. Temps also take off if exposed to load. I dont know what to say about the PI converter, except that it was some bastard collection of components and thrown in the trash. the BTS had the 2nd and 3rd direct clutches were hammered. [/QUOTE]
