| Description of the problem | 1. Exceptionally hard downshift under acceleration. 2. Under light or moderate acceleration, would start in 2nd gear. Possible to move selector to 1st gear. 3. At full stop would hunt from 1st to 2nd gear. Unintended forward movement with foot on brake. In one instance pedestrian walked in front of vehicle when this unintended movement occurred nearly pinning pedestrian between 2 vehicles 4. Under acceleration jeep vehicle seemed to go out of gear and into neutral at about 60 to 65 mph. Loss of forward momentum and fuel shut off occurred . The transmission resumed acceleration but with very deliberate and extended gear selection. While accelerating to pass a semi on a 2 lane highway with long uphill grade i got alongside the semi and could see the drivers door in my peripheral vision. The jeep vehicle kicked into neutral , the fuel shut off occurred and i lost enough forward momentum to not complete the pass safely. Another vehicle appeared over the crest of the hill some distance away and i was able to brake hard enough to get back in line with the semi. A head on collision was averted. While traveling on a federal highway in colorado with a long gradual uphill grade and cruise control set to 65 the jeep vehicle selected neutral causing rapid increase in rpm to fuel shutoff point and loss of forward momentum to about 35 or 40 mph. After transmission returned to a gear i was able to resume travel and click the cruise back on. This type occurrence became frequent. Jeep vehicle svc tech drove vehicle over 160 miles and was able to replicate the occurrence. The bands were tightened and various other little fixes. Jeep vehicle now selects 1st gear to start. Jeep vehicle no longer hunts from 1st to 2nd. Jep vehicle has started to kick into neutral again. Repairs started at about 5 or 6000 miles and have now totaled 6 attempts to repair this unsafe (in my opinion) variety of complaints all centered on malfunctions in (apparently) the transmission. *jb |
