Need opinions... Got a 350 TBI 700R4. Ok I rolling along in 3rd at lets say 50 and I let off the gas and it coasts normal for a few seconds and then it bogs down like a manual tranny does. (compression brake like). Is this the torque converter unlocking? If so shouldn't it do this after I use the brake and not before? It may be normal, but it doesn't seem right to me. Don't you buy no ugly truck!
