So the FM146 is on its last legs with a bad input shaft bearing. I pulled a MD05 from an 00 explorer yesterday. I got the shifter and the tunnel plate. I already did the 4.0 clutch swap like 16 years ago which by the way was one of the best upgrades people can do with their 2.9. So here are my questions...
The top plate does not have the neutral switch. Should I get a plate with one or just bridge the wires. If I bypass it how does 4low work? I have the electronic xfer case.
The transmission has a 98 part number. Truck had 210k on the clock. Not sure if the transmission is original to it or not. Shifter bushings are tight. Gears and case looks super clean inside. Input shaft has a movement though and the tip which goes into the pilot bearing was rusty. I took some emery cloth to it when I got home. It is not gouged but it is pitted and no longer machine smooth. Will this be a problem? How much play can the input shaft have and still be good? Was thinking of doing bearings before i put it in. I have a press which I think is the only special tool needed other than the 55mm wrench. A large crescent wrench should work too right?
Since I already did the clutch swap many years ago do I need to change my 2.9 hydraulics for 4.0 stuff? I know it is a good idea to change the slave when I have it out but if I choose not to will there be a problem? What is the difference between the two engine systems? I have read many threads. Some people say you need to others do not. What is the real answer?
And finally the shifter moves forward on the M5OD, what does that do the carpet? Will I have get a new carpet so I do not have a gap at the bottom of the shifter boot? My original Interior and carpet is in very nice shape. I don’t want to replace the carpet if I do not have too. A gap in the carpet will bug me though. None of the threads have discussed the carpet.
Thanks guys
