So I know this is an MJ forum but ya'll have helped me out as a jeep fan before... I have some transmission issues. Those being a bad surge. I bought my 96 Grand used and it didn't even move. Changed fluid and filter and it moved but barely. Changed the OD solenoid and Gov Pressure sensor and it worked for a bit, drove it to work no problems for a couple weeks than bam, right back to surging from 1500-3200rpm, and not going into gear barely at all going from a stop. I have since changed TPS, MAP sensor and idle air temp sensor and nothing has changed. I found a large amount of shaving bits in tranny filter last change and a large, brass/copper piece resembling a piece of flat washer. I was leaning toward torque converter but don't get why it'd go in and out of functioning. Any thoughts guys?? Thanks a ton!!
