Hi guys, long time lurker, first time poster. I have a ‘01 Rubicon I just finished piecing together out of 2 different ‘01s.
I picked up Rubi #1 from my buddy who bought it for $250 with a known bad transmission. It ran and moved in 2nd-5th when cold, but the trans raised all sorts of **** anytime it was running. After warmup the trans slipped so badly it wouldn’t move under its own power.
Not a problem, as I also have Rubi #2,which I got from a guy locally parting it out. It had a bad ECM and angle sensor, but a good engine and trans, with only 2300 hrs.
So, I got the engine and trans swapped from #2 into #1, reusing the angle sensor from #1.
Here’s where I’m running into issues. The motor starts right up, there are no diagnostic codes, and I believe it’s building oil pressure as it’s supposed to (though I admittedly haven’t tested it). But, in no setting will it move forward or reverse. I hear the shift motor doing it’s thing abd every so often I’ll get a very faint lurch from D2 to D1. But otherwise, no movement at all. I need to reiterate, the motor came out of a running Rubicon that functioned as it was supposed to until the ECM and angle sensor took a dump. What am I missing?
