I have a problem that has yet to be resolved...
History:
I purchased a low mileage (76k) 1987 BII, non-running. It had been sitting for a long time and required a bit to get it running again. New head gasket, new fuel tank and sending unit, lots of new sensors, new radiator, new filters, the list goes on.
The engine runs strong. My problem is with uneven power. What I mean by that is if the truck shifts into 4, I will never get above 45MPH, floored. If I shift it down, the engine has a higher RPM and will gain speed. In addition, if I take off from a dead stop in 1st, it is VERY sluggish until the engine's RPM gets higher (sorry, don't have a tach so I don't know what the magic RPM level is). It starts really taking off at higher RPM.
My thought is that perhaps I have a bad torque converter (could it go bad due to sitting for 10+ years?), or maybe the entire trans. The truck shifts between all gears just fine, so I suspect that the tranny is fine. Do you have any suggestions on what to check or where to look?
