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!!

Yep, automatic. Couple friends keep pointing me toward other sensors.... TPS, MAP, but I replaced the TPS to no avail.

So I am a proud 89 MJ owner but a Jeep lover in general. I don't know if this is frowned upon here or not... but I am going to ask for assistance with my 96 Grand Cherokee. Problem: Transmission slips/surges/bucks, just does not seem to know where its at. So far I have changed the fluid AND filter, changed the Overdrive solenoid and Governor pressure sensor and I grabbed a USED tranny brain from salvage yard, in an attempt to see if the brain was bad. Well its still doing the same things. The only things I have yet to do ( short of replacing the tranny) is I didn't change the transducer WITH the gov. pressure sensor and I hadn't had the brain actually reprogrammed by dealer. Any help would be great guys!
