I've got a 2000 Sahara, so 4.0, 5 speed. I'm swapping the engine cause she's dying on me. Local guy has a 4.0 from a 2005 6 speed. Can I swap just the engine or will I have to do the transmission as well?
I'm keeping the current transmission if possible. So all I need to do is put my 2000 PCM on the 2005 engine, use the same flywheel, and move the CPS?The flywheel is different (though they will bolt on) and the crankshaft position sensor is in a different location. If you match the flywheel and transmission with the PCM, it should work. So if you keep your 5 speed transmission, keep your current PCM and flywheel.
Thanks for your help. Yeah it was the camshaft synchronizer before 05 I believe, then it got changed to the OPDA - I think.The crankshaft position sensor should remain in the stock 2000 location, yes. It's in the transmission bellhousing.
I think that is all, but there may be a few other differences I'm not aware of. Hopefully someone else can comment on that. I know the camshaft synchronizer is different between years, but I'm not so sure that will be an issue.
It would help if you more clear. All TJ 4.0's will accept all TJ transmissions regardless of year in that they will all bolt up in place of each other.Cheers.
Turns out I misunderstood. He has a 6 speed and was trying to put it in.
So now it's a 4.0 from a 5 speed, either a 2004 or 05. Does that change anything?
Jeep used three timing methods, Distributor, Camshaft Synchronizer (the FSM refers to it as the Oil Pump Drive) and the Oil Pump Drive Assembly. 97-99, 00-04, 05-06 respectively. The hole in the block and the drive gear for all 3 methods is the same. You can run an 05 engine in a 99 if you swap over all the sensors to the 99 and it runs the distributor just fine.The crankshaft position sensor should remain in the stock 2000 location, yes. It's in the transmission bellhousing.

Thanks for the info. I'm putting in the 2004 engine and removing my 2000 engine.It would help if you more clear. All TJ 4.0's will accept all TJ transmissions regardless of year in that they will all bolt up in place of each other.
There is no 05 5 speed manual behind the 4.0, they are all 6 speeds. The 6 speed uses a different CPS in a different location.
What exactly are YOU trying to swap with what?
2004.2004 or 2005? 2004 engines are also 5-speed, and would probably make things easier.
Any 91-04 flywheel should be fine in those engines. It's 05-06 that has a different number of crankshaft position tics and a different sensor location.
