This code is programmed and storedin the SKIM, the PCM, and the ignition key transponderchip(s). When replacing the PCM, it is necessaryto program the secret key into the new PCMusing the DRBIIIt scan tool. Perform the followingsteps to program the secret key into the PCM.(1) Turn the ignition switch to the On position(transmission in Park/Neutral).(2) Use the DRBIIIt and select THEFT ALARM,SKIM, then MISCELLANEOUS.(3) Select PCM REPLACED (GAS ENGINE).(4) Enter secured access mode by entering thevehicle four-digit PIN.(5) Select ENTER to update PCM VIN.NOTE: If three attempts are made to enter securedaccess mode using an incorrect PIN, securedaccess mode will be locked out for one hour.

I have lots more to ask.trouble puttingso you are drivingand shifting and movingand 1>2 shifts are what, grinds, or balks.can you start engine in any gear (clutch to floor)can you shift any gear parked ,running, and clutch to floor and not moving. including REVERSE ?if all are good, cept the 1>2 upshiftthat means the clutch is not dragging.and the #2 synchro ring is worn.or running the wrong trans fluids.the newer transmissions are very tricky here.some are very upset with wrong lube. (or too low or is not black as tar)or mixing 2 brands, or using synthetic and its so slippery the syncrho fails, (cured many like this)if all this is true, and clutch don't drag (ever)then get the car to jeep and have them drain it and fill it with the correct lube and win.now answer 3:it might be just the shift linkage messed upif the 1>2 change balks. (not grind)on mine boxes i can hear the synchro's spin up.i can feel them engage, if i cant feel thatthen the linkage is bad.the word trouble does not say what that means.define trouble putting....find a shop, a Service tech, that owns a m/T box.and win.Some with a/t are clueless...ive blown more clutches racing than many ever drove. IMO, and remember it COST YOU NOTHING to ask. (I'm retired early, gin!)
