The life of a Magnum (and 46RE question)
Do you know when the vans went from rh to re? Same as pickups, or ??
Vans, rams, dakotas, durangos and grand cherokee switched same year.
OBD I is always RH 1995 older
OBD II is always RE 1996 newer
OBD I was fazed out due to increased EPA regs which mandated all vehicles upgrade to OBD II in 1996.Universal AL/DL(diagnostic) plug on every car , all makes, double O2 sensors, sealed EVAP can/gas caps and a much smarter computer capable of running auto trans.
We typically flash the second O2 and evap system out for A body swaps so it doesnt set a code for not having a cat or non sealed gas cap. One O2 makes it easier too.
The RE is controlled by the JTEC and JTEC+ PCM . If you want to use RH with OBD II JTEC you have to find manual trans pcm or get it flashed to remove auto trans code or it will set codes and go into "limp home mode".
If you want to find a 2wd od housing and output shaft, check with your local trans shop, they will probably have cores, they are more common than you think. Lots of 2wd daks and rams, durangos too.All vans. Many of my wrangler customers go 2wd to 4wd, feedback is $150-$200 cost to swap.
