OK it's a 2003 chevy s-10 v-6 vortec Pick Up truck crew cab 130,000 miles on it coming home from the PA area stopped for gas as I was pretty low WOW got gas in Paterson NJ $ 2.15 a gallon wow thats cheep well I will fill up I get 3 blocks from the gas station and the Check engine light comes on and it dosent feel like its moving anywhere first thing I say is bastards put water in the gas and screwed up my car no its just coincidence the truck runs fine so I rule out the bad/gas theory i get home only with 2 & 3 gear working no 1 st or 4 th gears I guess a fail/safe in DRIVE I hit the gas and she acts as if I have the brake on and the truck does not want to go any where( very very slow ) but if I place it in first gear It will go ....not like it's normal but enough to get it up to 30 or so and manualy shift to 2 or 3 and will go ok but at 70MPH it's reving at 3,000 RPM's so I guess it's in 3 and I have no ( 4 th ) overdrive well I goto autozone get the check engine light code and it comes up PO 758 shift solenoid electrical a $ 20.00 dollar part but someone told me have it checked by a MECH. because it could be giving you a false code and the trannmission is really shot - needs a rebuild what do you guy's think...... thank you in advance ANT
