***trans slip/99 wj-help??***
OK Gang..I have been thru some ringers but I keep putting the hammer down and she keeps getting from A to B. I did get that ARC pcm(bad 1 first but they overnited another the next day) so I am OK w/ it. I have been having issues with the trans since then tho & still an iffy idle but it doesn't shut off. Again, I replaced the PCM, fuel pump, IAC, TPS, map, and cranksensor. 2 new injectors..but it runs fine on the HWY for the most part. HOWEVER, I am very concerned about this transmission. Once it hits 2nd gear, it shifts fine to 2nd gear, but it slips a tad then catches and shifts fine into 3rd and 4th gear. There is no slip in 2nd if I shift it manually(which I do 95% of the time for the last month++) Secondly, when I'm in overdrive on the interstate, it struggles to find itself(or slips, whatever u want to call it) between 1700-1900 rpms. It's ok at 1900-2100rpms at about 75 mph. It bounces back & forth if I go below 1900rpms. It doesn't downshift though..Basically it drives fine at 55mph&75mph..but it does not like traffic on the hwy or slight hills..It downshifts fine and climbs strong on steep grade or deliberate passing..I swapped the filter & discovered the tranny is out of a 98. Again this is a 99 WJ 4.0L..I'm hoping not to pull the trans if I don't have to..Ideas? Thanks in advance Gang..JEEP ON!
