Transmission went bad, went to junk yard got a working one, has warranty. came with torque converter. Put it in yesterday, only put in 5 qts., seemed like it didn't want to go, would only go 25 mph at very high rpms. Found out that it needed more fluid bc we replaced everything. added another 5 qts. Now it stalls when I put it in any gear. Dipstick still reads low. I checked this while in was running and in N. Could the stalling be from very low fluid.
