1995 Chevy Van V8 Two Wheel Drive Automatic 174000 miles
This is a 1 ton step van, P30 series with dual rear wheels. The transmission was rebuilt 5 years ago and has about 30,000 miles on it. One day the truck runs fine the next day it does not start. Diagnosed the problem as a fuel pump so I dropped the fuel tank and replaced the whole unit (float, pump and sock). Put it all together drove down the road only to realize now the transmission is only operating in 2nd and 3rd gear. No 1st gear or overdrive. Even tried to drop the trans into D2 or D1 and still cant get into 1st gear. Any ideas from anyone would be greatly appreciated.
