545RFE differences
So have an 04 that will only move in reverse. Got a wrecking yard replacement but 2x4 rather than 4x4. I pulled the new one down in preparation for changing the tail shaft but now that I look at it, it seems to be the same. Any of you guys know if there is actually any difference between the 2x4 and 4x4 545rfe?

I dont know for sure....... If you do get away with just changing the extension housing, I would like to know.... :
I thought the rear shaft was longer in the 4X4's |
Since I have 2x4 taken down already, I will compare them side by side and post my findings.

call these cats. http://www.areds.com/,,,,,,,,,,,,,,have known them since the late 60s. 90% of the parts trans shops buy come from them. if they cant answer you Q no one can.

After pulling the tail piece from the 2x4, I found out that they are the same. Bunch of work for nothing. Good to know, though. Put it all back together now. May keep the 4x4 for future friction replacement just in case I need a spare.

Good Luck... Hope it works out good for you !!!!!
Keep us posted.... |
I havent had a oprtunity to work on one but from what I understand about the 518 and electric nissan tranies its most likly a accumulator or bad electronic control part...
wich means anything from the wirng harnes to the computer or selonoid"if your lucky„ thats a cheap easy fix. oh also be very carefull about removing frictions from their drums some of these can be under extream pressure ...for instance the overdrive unit in the 518 is under 400lbs of it and if you happend to get the snapring out you would have these steels and frictions flying at you and any near by ...:yikes: |
Gorts what does that have to do with 45RFE???? Just for future reference the 4X4 is heaver duty and has a couple more plates and friction discs in the clutch pack...Bill

So if you want to remove the overdrive clutches and steels you need a press now the 545rfe may have the same issue dont start pulling parts out of it with out a repair manual. most likly the 545rfe that hes swaping just needs a servo part . Or has a pluged screen but hes pulled it so hopfully his swap will work. |
Doesn't the Cummins use the 68RFE or The Heavy Duty Aisin 66RFE???? The Cummins would smoke a 45RFE in about 1 minute if it would bolt up.
