Hey guys well here is the story.. Today I was driving my truck home from work and I ran through a puddle. shortly after that I noticed my truck was acting up so I took a couple laps around the block to see.. The transmission would get to the top of 1st and would not shift into 2nd unless i let off and then got back on it and it would act like a "neutral drop".. and It refuses to shift into 3rd gear.. Now here is the weird part, the truck has a loud hissing noise coming from right under the cab, almost like a huge vacuum leak. ALSO, If I manually go from 1st to second using the column it will shift into second after a small delay, but when I put it into drive it does not shift into 3rd. Truck has a mild 350 with a turbo 350.
