I have a 1995 Jeep cherokee country it was in 2 ish feet of water sat for almost 2 years i flushed the trans and motor 3 times changed the trans filter and replaced all fuses the truck runs great but when you try to put it in drive if you give it gas it feels like it slips a little/wants to go then starts to cut out But it idles fine and when you put it in low the jeep will move with no problem reverse works just 4 high and drive will not work it makes the jeep stall new plugs rotor ect but like i said its fine until i try to go into drive and 4 high and 3 what could be doing this? is there a relay i could be missing that i didnt replace?
