NV3550 trans rebuild kit

[Scorechild]

Hi
My 2000 2.5 TD XJ has an NV3550 trans. I have another trans spare which I want to get rebuilt & then swap in. Rebuild kit pricing varies a fair bit (Mopar, Crown) and there seems to be a Getrag kit that might be right, but I'm struggling to work out if it fits... The (US) places selling them have no idea (mainly cos of the XJ TDs not being a US listed vehicle).

There's a rebuild kit (bearings, syncros, seals) and also a 'small parts kit'.

* Mopar rebuild kit # R0035503AA, $348 - www.factorymoparparts.com/r0035503aa.html

* Crown rebuilt kit # BKNV3500, $265 - http://www.amazon.com/Wrangler-Beari...ef=pd_sxp_f_pt

* Crown rebuild+small parts kit from Quadratec, $499 - www.quadratec.com/products/52170_0111.htm

* Gertrag rebuild kit # BK235FWS, $215 - http://cobratransmission.com/index.p...cts_id=5005016

* Getrag small parts kit, # 404001A, $21 -

Does anyone know if the Getrag kit matches please? Searched so hard, but getting no further....

I Think you will struggle for info here as our Aussie XJ's didn't come with the NV3550. Only AW4 behind the 4.0L and AX15 in the TD. They may be in TJ's but not sure, and no diesel in TJ's either .

...damn.
(Yes, NV3550 used in2.5TD TJ 2002-2004 (your TJ comment noted) and 2.8CRD KJ 2000-2006 or something like that. Should I repost in those boards here?

[Mudmonster]

the NV3550 is used in TJ Wrangler and XJ from 2000, which replaced the AX15
as long as the rebuild kit is for the NV3550 the kit would fit.

if the NV3550 in a TJ was different to a NV3550 in an XJ it wouldn't be called a NV3350

the same as the AX15 any rebuild for the AX15 will fit an AX15

the * Gertrag rebuild kit # BK235FWS, $215 - http://cobratransmission.com/index.p...cts_id=5005016
states 2000-up

you would be pretty safe with getting this kit

Are the part numbers for the kits quoted in the OP the same kits for Aus NV3550? My 2nd gear syncos are gone in my 02 wrangler, looking to put a kit through it.

The kit numbers apply irrespective of country... but not irrespective of vehicle or year. So not every 'NV3550 rebuild kit' fits every NV3550 in a specific year (e.g. there are 2 kits listed for year 2000). Variations are:
* Synced or non-synced reverse
* 30mm or 33mm OD (outside diameter) cluster journal bearings
* 1-part or 3-part syncos for 1st+2nd gears.

Note that the 'rebuild kits' include the 'small parts kit' so no need to order that in addition.

Kits made by Mopar, by Crown and by Getrag. Crown and Mopar kits are more likely to fit, since made specifically for Jeeps (although not for the TD) but Getrag is by far the cheapest. Cheapest supplier of Getrag kits I found was Cobratransmission.com, but AmericanPowerTrainWarehouse.com knew more and advised correctly.

Since previous post, I ordered correct kit for my mid-2000-built XJ 2.5TD (kit BK235FWS) and had the box rebuilt and about to fit (Mudmonster, you were correct....)

Getrag rebuild kit numbers & fitment:

BK235B, 98 & up, Non Synchronized Reverse
BK235C, 97 & up, synced Reverse (1997-Up) (Cluster Journals 30mm OD
BK235E, 00 & up, synced Reverse (2000-Up) (Cluster Journals 33mm OD)
BK235DWS 98 & up, Non synced Reverse (3 piece 1-2 Synchro, 30mm OD)
BK235CWS, 94 & up, synced Reverse (1 piece 1-2 Synchro, 30mm OD)
BK235GWS, 97 & up, synced Reverse (3 piece 1-2 Synchro, 30mm OD)
BK235FWS, 00 & up, synced Reverse, 3 piece 1-2 Synchro, 33mm OD)

Apologies if teaching grandmother eggs etc... I just went round the loop a bit on this to avoid paying Crown/Mopar parts. My advice is email AmericanPowerTrainWareHouse with your model/VIN.
