Having an issue with my 96' Land Cruiser...background, 211,000 miles, replaced engine at 200K miles with a used motor that had 70K miles. Truck ran fine. Have not had any issues, then truck died on road, would not restart, I was not driving it. Towed the truck approximately 200 miles, I was not there when it was towed. Picked up truck, brought it home, coil wire to distributor was off, put wire back on, truck started right away. Drove truck and it was not shifting correctly...would not go over 40mph. Checked tranny fluid, VERY low, added tranny fluid, test drove, feels about the same, won't go over 3K RPM...even in neutrel it will not rev over 3K. Not shifting well at all, but thinking that's related to not developing any power. Not sure where to look first. Any ideas?
