Hi, I have a 99 Silverado 5.3 4x4 that I recently swapped out trans from a 2000 blazer 4.3. I had too change out bellhousing from the blazer too my Silverado bellhousing. Was 1.5 inch differance. And purchased a new torque convertor. I have good line pressure. But no movement in any gear. Checked linkage inside trans, all hooked up and moving. Cable shifts fine. Transfer case is shifting thru 4x4 2x4. Cab hear engaging, and i can not roll truck when. In park. So that tells me that's good. Only wierd thing is in gear with rear of truck jacked up. I can spin tires by hand easily in gear. Little more resistance in reverse. Thank you for any help.
