TRNW-2: R&R Tips 845RE 17 Jeep Grand Cherokee

[tucker tuckertrans.com]

I didn’t get any hits on this, or at least I didn't see any, but I can tell you don’t go by the book.  Don’t pull the belt or ac compressor or either catalytic converter.   The goal is to get the left motor mount off.  The book also says to pull the intake plenum but that’s was a no go for us also.  We took the left motor mount off underneath working though the belt area.  We just jacked the engine up a little and stuck a 2x4 between that aluminum oil pan and rack the removed the mount.  This allows you to remove the starter.   Unwire the starter and get it out of the way.  We took the transmission cooler off and got it out of the way.  Be careful not to damage the heater hoses removing them from the cooler because replacing them could make a tech suicidal.  We removed the exhaust from the crossmember all the way back.  Be careful and don't let the bell housing hit the O2 sensors.  I recommend getting 2 techs to stab and unstab It because it's tight.  This thing is hard to pull.  I think it is a unit that really needs to be dyno'ed before installed.  That's our take.  Book pays 12.1.  If we do another one we will get 16 or we are out.

Group,

We have yet to do a 4wd Jeep Grand Cherokee 3.6 with a 845RE.  It says 12.1 hours and I was wondering if anyone has any short cuts on it?
