My old transmission (aka Courtney Love) was so loose and sloppy. I just replaced the transmission with a low mileage junkyard transmission. It shifts so crisp and clean it has truly altered the driveability and character of the Jeep in a positive way. I filled it with Red Line MTL naturally. Drives like new. I liked this so much I just grabbed the transfer case to do the same. I won't be surprised it it further smoothes and quiets the ride. I will swap the SYE over to it. If this keeps up my engine is next. I really must reimport this TJ. It deserves to come home.
