Re: Any NEW news on jeep autos??
You didn't specify "what year". If it's a 02 or older it's a 32RH/999/909/904 which has been around in one form or another for a very long time.
Disable the lock up torque converter
Install MASSIVE auxillary cooler
Relocate vent line
Install deeper pan w/extended pick up
The DC converters like to release some converter clutch material as they age(the only ones that I've ever heard of or had this happen with. This may be limited to the Caravan crowd, however - many frequent the local shops for such failures). I was quite dismayed when my SE had this feature. It only knocks about 200 rpm off the tach when engaged ...it's main feature, according to the owners manual, is to lower trans temperature. These trannies survived for many miles before the creation of the lock up torque converter. Since fuel economy is somewhat of a non-issue in a jeep ....a massive cooler should compensate for the added heat factor.
Unless you have an idle problem (as in too high - which is unlikely in a newer setup), an auto is, IMHO, easier on the drivetrain. Torque is constantly applied and the shock to downline components is minimized.
You gain some flexability in some areas ...lose it in others. The manual is fine in a rural, suburban, or highway environment ...around town, however, it's like a whole lot of motion ot go a few feet given the torque plateu of the 4.0. BTW- the AX15 is also considered medium duty.
