What parts fit?

[BullDogSix]

What Disco parts fit a RRC? I've searched the forums and the net for this and I'm still a little fuzzy. As I understand it, most drivetrain parts from a series 1 Disco will fit the RRC...right? What else?...I'm sure there has to be many common electrical and engine parts.

Disco's are far more common in the bone yards around here than classics...and trying to tell the parts monkeys that you want a Disco part for your RRC just causes blank stares, drooling and an overwhelming desire to do bad things on my part.

Specifically will a 1996 Disco auto trans from a 4.0 fit a 1994 RRC LWB with a 4.2?

Thanks

I just put a ZF from a 96 (or was it a 97?) Disco in my 95 LWB with no problems. If you are going to use the torque convertor from the newer ZF/GEMS motor D1, make sure you get the flexplate and all adaptors from the back of the engine in the car it comes from as the convertors are quite different, but are otherwise totally interchangable.

Thanks 57loboy! Exactly the kind of info I was looking for. Any other thoughts on what else fits from the series 1 Disco?

I believe the engine ECU, lock ECU are the same, most of the dash components, front & rear axles are the same too. I am sure there are others that I am missing - I just had a conversation with someone about this yesterday as I am in search of a donor 95 RRC to park behind my barn and was considering a 95 D1 as well.

Just talked with the junk yard...the trans in question has the TC...but the flex plate is not available. Will the TC from the 94 RRC fit into the D1 trans? I'll look around for a D1 new/used flex plate also.

The Borg Warner will work with the Disco ZF HP22. As far as the engine management stuff is concerned, only 1994 and 1995 DI's used the Lucas 14CUX EFI System which is what all the RRC's used from 1990 through 1995. The DI 3.9L in 1994 had the v-belt setup which is compatible with later RRC's while the DI in 1995 had the serpentine belt arramgement just like the 1995 RRC.

CV's and swivel balls from mid year 1993 on are the same in the RRC as what you would find in the DI. You'll know whether they are compatible by whether or not you have 24 spline diffs and axles on your RRC. The front prop shafts are not interchangeable as the Borg Warner transfer case uses a shorter one than the LT230.

The rear diffs with the three bolt rotoflex flanges are the same on the last of the RRC's and almost all (except the XD) DI's. Otherwise, the RRC's (SWB) had the desireable four bolt flange at the rear. The rear axles are interchangrable from mid 1993 on.

On the interior there is less that is interchangeable if you are talking about RRC's before 1995. DI's in '94 and '94 used the same alarm ecu as the later RRC's but from 1996 on they were completely different. The window lift ECU is only interchangeable on DI's with the 1995 RRC. The same it true of most of the switches and controls. The HVAC is entirely different.

Without a doubt I've left out way more than I've listed regarding interchangeability and compatibility. If you have a specific question post up and I'm sure someone will reply in even greater detail.
