I helped out a friend by putting on a new injection pump for him. Truck is a 2000 auto. The engine is no running fine but he called me 20 minutes after picking it up and said the transmission was starting off in second and had no overdrive. After stoping for at a store he said the transmission seemed to be working ok. Also the fan is noisy even when the engine is cold. It is not locked up but it is very stiff compared to my truck. I washed the engine and radiator with a hot pressure washer before I replaced the injection pump. Do you think this may have hurt the fan clutch. (I washed it pretty thoroughly :-laf ) Also could un-pluging the tps of caused the transmission problem? or was it the pressure washer too!?
