Hey Guys, Well, I just finished replacing the water pump on my 78K5 cause the old one was leaking. I also fixed an electrical problem of exposed wires where the starter wires go into the small tube between the headers and frame. Well, after refilling all the fluids, the transmission (TH350) doesn't want to shift like it's supposed too. It won't shift into 2nd until around 45 mph, which is high, and once it gets there, it doesn't want to downshift. Now the damn thing worked fine before I changed the pump, so what do ya'll think is going on? It's got me stumped. Thanks for the help, and sorry for the long post. Eric78K5 K5-Because Size Matters!
