....You will be throwing CEL's because the computer is looking for the tranny. SCT (at the moment) will not be able fix it from what I hear.....
.....PCM flashed, (but CEL will be permanent)...
I'm currently doing the same swap in my 98 5.9 Grand Cherokee.
I've dealt succesfully with that CEL issue on another build of mine - ultra simple 20 minute fix laying around in jy's everywhere - use a 98 Ram/Dak 5.2 or 5.9 5spd PCM!!
Spent the usual time going back and forth on the auto trans delete thing talking with Hemifever and B&G etc - in the end I decided to save myself the headaches. Now when Sean writes the tune he doesn't have to deal with the auto trans/CEL stuff.
Other than that, right - there is the xmember mount and custom dshaft to consider.
Flexplate indexing and notching for CKPS - might or might not be advisable depending on what you're gonna run at for horsepower and rpms.
By re-drilling I assume you mean widening that one offset hole? Or are the bolts a different size too?
If it's cuz of the offset hole there's a few ways around that too.
Probably easiest to use a 5.2 flexplate - just make sure you get the 90 degree FP, some 5.2s did come with an offset hole.
or.... drill the weights off your 5.9 FP (I assume you have a 5.9 in there?) They look to be pinhole welds that should be pretty easy to drill out without getting into the FP itself but I haven't tried that route myself.
or.... get your converter built with the mounting tabs in the correct 90 degree or offset for your motor (and correct bolt size if it turns out to be different) Martin Saine can do this as needed...
Fourth - and my choice: Use the stock 727 flexplate.
Reason being - your 46RE, RH or 44RE was made with that CKPS relief in it - somewhat reinforced, cast/machined to minimize stress there.
That's why I asked about your HP and RPM use - per Martin, the relieving the FP offset hole/notching for CKPS thing is OK for a streeter, even with a bit of extra HP - but if you're going for big HP and higher RPMs it's much safer NOT to do either of those.
So what about the CKPS you might ask? - I'm going with a damper mounted trigger wheel for the stock sensor. That allows for the use of any FP - including an SFI approved unit.
One other thing you'll need - fitting adapters. The fittings into my 727 are 1/8NPT . Assuming your 46RE is like mine the trans fittings are 1/4NPT and it has bigger lines.
Hardware store should have adapters - if not try a hydraulic hose shop or possibly even one of the performance fitting makers like Russell, Aeroquip or Aeromotive among others. I just got the Russell catalog yesterday but haven't looked to see if they have 1/8 to 1/4 NPT adapters (kickin myself in the butt over that one - ordered lots of parts from Summit including Russell EFI adapter fittings - found out the day the package arrived that I need trans adapters too
NOTE: If you are having the 727 built they can enlarge the holes to 1/4NPT - but obviously that's not an option on a tranny that's already together.
Looks like the rest of it is a direct swap: shifter and TV arms and brackets look to be the same, speed sensor and NSS switch also.
now if someone can just post a pic of a Dodge 46RE or RH shifter bracket in my thread in the tranny section I'd be real happy!
