Like the title says, my AW4 is not wanting to shift out of first on its own (for about a week) and today it slipped going from 2 to 3rd.
a little background:
95 XJ, 4.0, AW4, 231, D30, 8.25 (both with 4.56s), 203,700 miles.
everything was working fine until memorial day weekend. on friday after work i noticed a large pool of coolant under my front pass side. after tearing the header pannel off, i discovered a 2 3/8" crack on the brass band that connects the cores to the plastic endcap on the radiator. she had been running slightly warm so i took the opportunity to upgrade to a CSF 3 core. it took till tuesday for my order to be processed and i finally got my new rad on monday following memorial day. i took advantage of the down time to get some projects done on her- rear disk brakes ZJ proportioning valve, KJ ebrake cables and a 39 tooth speedo gear. i finally got the radiator all installed, filled and ready to start it up to circulate the fluid (i also did a flush prior to installing the new rad). it didnt want to turn over. turns out that my alternator had siezed for some reason and wouldnt turn at all, in fact the pully sat asque and the battery was dead after sitting for two weeks. so i took advantage of the opportunity again to upgrade instead of going stock. i put in a 136 amp alt for a 97 zj and charged my batt.
the problem of not wanting to shift out of first started on my test drive following the above mods/repairs. it will not want to shift out of first gear on its own untill 25 MPH under extremely light acceleration (the kind where old granny would zoom by and flip me off). anything faster than that and it wont want to shift on its own without my help. if i momentarlily let off the gas when speed is between 20-25 MPH then gently reaply the throttle, it will shift to second then shift fine after that. except for hard accell- i tried to speed up where the lane adjacent to me ended and the car behind and to my left wanted to "pit" me. uppon applying aggressive throttle, RPMs shot into the red and the tranny felt like it downshifted back to first on the freeway on ramp! a temp release of the throttle and it behaved normal again.
today i was coming home from work and the temp on the overhead consol read 115*(a "warm" day here in AZ). i turned right from a side street to a residential street. the tranny stayed in 2nd through the turn but when i reapplyed the throttle, i had nothing except coasting for about 50-100 feet, then i had power again. now it barely feels like its slipping between 2nd and 3rd gears.
tranny fluid was a little low following the rad swap, so i added some more Dex III (NAPAs house brand). i ended up slightly overfilling it so when i went for a little trip with 45 min of freeway driving, it started to spew out leaving a white cloud behind me. the trans fluid is dark and in need of replacing, but i now have to drop my tnt belly pan to drain it (coming this weekend with AA SYE)
the xj is my DD, but i do have another vehicle. i just dont like to drive my truck at 12MPG. so the sooner i have the xj back up and running, the better
thanks
