First, thanx for all the help I've found on this site! Now onto my current troubles, was driving my 91 previa with AT down the frreeway when something broke and while the engine was still running fine there was no power getting to the wheels, coasted to the road side & looked at drive shaft & U joints they are fine so I had it towed home, the engine starts & runs fine, the shifter cable moves lever on tranny but no go! Transmission fluid was full, I drained it, no metal in ATF no major leaks I'm stumped, any suggestions on figuring out just what went wrong??
