blue monday

I have a 1988 mj with a 4.0 and a automatic trans. There is a switch on the dash that is labeled power and comfort. I don't have a owners manual so I'm not sure what this option is. Can someone tell me about it?

I want to thank all who replied. It did help. I also had a talk with the Comanche and it agreed to behave and I agreed not to bring in the hammer mill. Peace has settled in on the reservation. For now.

what years of pumps will fit on a 1988 with a 4.0l motor? What auto trans was used in the 1988 with the 4.0l? Was the dip stick tube for the trans in 2 pieces with a hose or has this been modified by someone? one more, the wipers go real slow is this the motor or some hidden part I am unaware of? This is my first MJ and I'm starting to regret it already. The best part, it's a rust free truck and if it doesn't straighten up it's act, I'll sell it! I read this board all the time and I see some of the best answers. You folks really care and try to help. that is rare. Thank all of you and have a HAPPY THANKSGIVING.

Just a quick question, Can the oil pan be remove while the engine is still in the truck? I don't want to have to undo the motor mount and jack up the motor. It is a 1988 mj with a 4.0 iL6 motor. I just want to change the oil pump and inspect the bottom end. One of the former owners used a lot of sealant on the pan and it may have fouled the pump, no oil pressure and it hasn't spun a bearing yet. If this is going to be a big project I'll sell the truck.
