Justin and I would like to start a thread about doing a transmission swap in an X-type, from automatic to manual.

After looking at some engine removal pictures by Jim Fenley, we realize this process is not for the meek.
It is for the enthusiast, the aficionados of the left foot.

So, what is different or needs to be considered in a swap?
beyond the obvious stuff like, nuts/bolts, clutch pedal, gear selector...

• 2.5 or 3.0 engine, does it matter?
• which year manual gearbox?
• wire harness differences?
• vehicle controller changes or reprogrammed bits?

I can really appreciate your project as I have a 3.0 manual and love it. Took me almost 9 months of searching to fine the exact car I wanted at the price I was wiling to pay. So much more rewarding to drive in my opinion. However, I can't recall anyone else posting a thread where that was done. Am guessing that the main reason is that by the time you factor in all the time, parts, possible fabrication, pain-in-the-*** factor etc., no one wanted to tackle it and/or didn't have the expertise. Probably just easier just to buy a manual car and build around that. Would be cool if you did it though.

 

I don't think any fabrication would be needed. I really don't think it would be a hard swap to do if you had everything needed, but then that would include a lot of little things too like the shift cables and shifter tower, the trim around the shifter in the interior...various bolts and things. The manual trans has been the same unit for all the years of the X types life so I don't think the year would matter and I know the 2.5 and 3.0 have the same bolt pattern for the bell housing so that's not a problem either. The wiring harness could be different, but then again ford might have gone cheap on it and used the same harness for both manual and auto, just not using some plugs and using others. Reprograming probably wouldn't be a big deal, but I'm sure it would be necessary, I mean you cant even install a new gauge cluster without reprograming the car haha. I think with a parts car it would be fairly simple, just labor intensive.

 

Alpha,
We are jealous of you as you were able to find a manual shift car. Here in the US/NA, the later cars came in automatic only.

Justin,
Good to know the bell housing and mechanical bits are compatible between 2.5 and 3.0, auto and manual.
Nice add on the gauge cluster, as the manual display may be different than the automatic equipped car due to the PRND321 indicator. The key question for me is weather the ECU needs to be swapped with the manual shift donor car or can the automatic unit be reprogrammed. Would the dealer be able to do such a reprogramming?
I know that Volvo cars have a security feature which crosses the ECU, gauge cluster, and the immobilizer unit, making a parts swap nearly impossible without dealer intervention and reprogramming.

Its only the wagon that don't come in manual in the US, the sedans did.



The Jaguars are like that too. I would think the ecu could be reprogramed though, but I'm not sure.

 

Doing some research at one of the parts places which sponsor JF... I looked at the engine wire harnesses: there is only one part number listed for AWD vehicles.... no differentiation between auto and manual... only between FWD and AWD... and further differentiation between diesel and petrol.

SNG Barratt - The Ultimate Jaguar Parts Specialist

This evidence seems to indicate that a tranny swap does not effect the wire harness (nor the ECU? which connects to the harness).

Looking for the ECU's the parts listing only differentiate between 2.5 and 3.0 Liter engines, not based on transmission. Although the VIN numbers are highly selective, so Jaguar may have made a rash of manual tranny cars and put them all in a sequential VIN order? I doubt it. The data seems to indicate that the ECU is engine specific and not transmission specific.

next: gauge cluster...

Herminator

 

Looking on the SNG Barratt site, the gauge cluster is not transmission specific.
One more issue taken off the list.

But snooping around the JagBits site, I found a transmission control module which is probably dedicated to driving the automatic transmission? and affecting the ignition timing or other interactions with the engine control module?

I will see if I can find what the manual transmission version would look like (if it exists). Hopefully a simple omission of the automatic tranny control module will still allow the rest of the vehicle system to work with the manual transmission.

Herminator

 

Install JEPC, you should be able to use it to find which parts have different versions for manual/auto.

Oh, and the automatic gear selector veneer surround fits the manual too.

 

Good suggestion. I have loaded the JTIS database up to 2003. It is a bit clunky, and does not always show the details on the part numbers.

So far I have determined that the manual transmission conversion is mechanically simple.

The next part of the study will focus on the ECU and the electronics.
Who is the ECU expert on JaguarForums?

Herminator

 

Keep us posted. I'd love to do this if I don't have to sway a wiring harness.

My car is mint, but my automatic tranny has been acting up for over a year. I don't drive it because it often will leave me stranded.

 

X Ray,
This is what I have found out so far based upon my research into various parts listing and manuals.

============================== Manual Transmission Swap
DRAFT

Guideline for converting an automatic transmission Jaguar X-type into a manual shift version.
Note: the reverse conversion (from manual into automatic transmission) is also possible and many lessons/steps can be applied.

Disclaimers:
1) Which years are considered in this conversion guideline doc?
This guide applies to all X-type Jaguars (from 2001 to 2009)
2) Which engine type is considered?
This guide applies to the petrol/gas engines, not the diesels
3) Which drive line?
This guide applies to FWD and AWD, but care needs to be used in finding a donor car with manual transmission of the same drive line type.
3) Which else?
This guideline assumes that the automatic transmission car is operable and complete... and is a good candidate for surviving surgery.

Notes with a question mark (?) are yet to be verified.

Below is a (draft) list of physical parts needed from a manual transmission donor car:
(in the US/NA markets, manual transmissions were available up to year 2005)

a) the manual transmissions, including
front drive shafts (?)
output shaft speed sensor (?)
slave cylinder (and hydraulic hose to master)
mounting points (?)
wire harness to manual transmission (?)

b) interior gear selector including
linkage to the transmission
interior shift boot leather and sound insulation materials
(wood veneer trim piece is the same for both transmission types)

c) clutch assembly including
foot pedal, firewall mount, master cylinder
clutch pedal cancel switch (top of stroke) to ECM (cancel cruise control)
clutch pedal safety switch (bottom of stroke) to ECM (starter engage)
? clutch master fluid level circuit
? any differences under the hood by the brake master/clutch master?

d) brake pedal assembly including
foot pedal, firewall mount
brake pedal switch (top of stroke)

e) engine control module (ECM)
? reprogram the existing unit from automatic car
? replace with ECM from manual shift car? (these are engine and year specific)


Transmission Exchange Process: (not yet complete, input welcome)

0) rebuilding of the donor manual transmission, transfer case(?) and new clutch
1) lowering of the engine and cross member in the automatic transmission car
2) disconnecting the automatic transmission, wire harness, shift linkage
3) changing over the brake and clutch pedals and master cylinder
4) changing over to the manual shift linkage
5) installing the manual transmission onto the engine carrier and transfer case(?)
6) raising the engine cradle and connecting to the clutch master and shift linkage
7) reprogramming the ECU(?)

DRAFT

 

X Ray, Justin,

You guys want to chip in some time and check out a few details?

1)Do your automatic transmission X-types have some extra wire harness connectors under the dash for the clutch upper and lower switches?
2)Do either of you have the repair manuals for the X-type, which spells out the clutch change out process?
3)What do you see by the brake master cylinder in the engine bay? Do your cars have a space for the clutch master cylinder?

thanks,
Herman

 

I have a 5 speed so I cant really help with that.

 

all right guys,

Aonsaithya sent me a gold mine of information and I was able to put together a pretty good guide on the subject of converting an X-type from automatic to manual.

I am also amassing a few web sites which can help find "donor" cars (salvage yards and rebuildable cars)

How do I post a PDF file and share it with you for feedback?

Heminator

 

Oh, a guide already? That was fast

For sharing, this should do it:

There is now a draft of the X-type Transmission Conversion file.

I have posted an ODT document file for edits and inclusions.
(both DropBox and Mega are "membership based" file share sites... anyone suggest an "open file share" site?)

Not to revive an old thread, but i have an '06 X-type Wagon and I'd love to look over the aforementioned guide. Unfortunately the links provided no longer work. Any suggestions?
