I am helping a friend of mine w/ his 94 Grand Cheroke. The car has been sitting for a while. From what he says, the car was in a shop, and the shop tried to clean a sticking Transmission valve, but didn't do a good job, or the Valve neds replaced. So he has no first gear, and sometimes looses overdrive. I drive a Nissan 240sx w/ a 5 speed, so this is new territory for me. Where is this valve? He mentioned something about a pump too. Is this in the transmission, on the outside, what? I just figured the Jeep gurus could help me on this one. Thanks.
