It's been a long time since I did a transmission removal. First time on a Jag. But today is the day the transmission from my 2004 XJ8 COMES OUT.

 

These are relatively easy.

Drain fluid
Remove catalytic converters
Disconnect torque converter bolts
Remove trans mount
Disconnect shifter cable
Disconnect wiring
Disconnect cooler pipes

Make sure you have long extension, some of the bolts at the very top can be a pain if you're doing this on the floor.


CAUTION:
Under no circumstances must the flexible coupling (or its fixings) be loosened or removed from the driveshaft.





Detach the driveshaft from the transmission flange.

1.  
   • Mark the position of the driveshaft in relation to the transmission flange.
   • Mark the position of each nut and bolt in relation to the transmission flexible joint.

CAUTION:
Make sure the front of the driveshaft does not put an excessive load on the center bearing. Failure to follow this instruction may result in damage to the vehicle.




Using a suitable securing strap, reposition and support the driveshaft to the vehicle body.


Detach the transmission fluid cooler tubes from the oil pan.


Detach the transmission fluid cooler tubes.

1. Remove the retaining bolt.
2. Remove the retaining plate.
3. CAUTION:
   Make sure the transmission fluid cooler tubes are not removed from the automatic transmission by using a pry bar. Failure to follow this instruction may result in damage to the vehicle.
   
   
   Detach the transmission fluid cooler tubes.
   • Allow the transmission fluid to drain into a suitable container.

Remove the torque converter rubber inspection cover.
CAUTION:
Make sure the automatic transmission weight is evenly supported on the special tool. Failure to follow this instruction may result in damage to the vehicle.




Install the special tool.


Install the rubber blocks supplied with special tool HTJ1200-2, between the front subframe and the oil pan.


Lower the rear of the transmission.

1.  
   • Remove the automatic transmission support retaining bolts.

WARNING:
Secure the automatic transmission to the special tool using the tie down straps. Failure to follow this instruction may result in personal injury.




Install the tie down strap.


Detach the selector lever cable.


Reposition the selector lever cable.

1.  
   • Remove the retaining bolts.

CAUTION:
Make sure the transmission control module (TCM) and main control valve body is protected against electrostatic discharge. Failure to follow this instruction may result in component damage.




Disconnect the automatic transmission electrical connector.


Remove the rubber access cover.


Remove the torque converter retaining bolts.

1.  
   • Rotate the torque converter to gain access to the remaining bolts.

Remove the automatic transmission retaining bolts.
WARNING:
Do not let the torque converter drop out of the automatic transmission. Failure to follow this instruction may result in personal injury.

Special tool shown removed for clarity.




Remove the automatic transmission from the vehicle.

1.  
   • Remove the retaining bolts.

Hi Two Dubes,

Just curious, but why are you removing the transmission?

If you don't have the X350 Workshop Manual that JBzXJ40 referenced, you can download it in six sections here:

Ouch

 

 

Thank you for sharing... would you mind sharing more of how it went?

I am thinking on the same thing on my car. It does have different symptoms but I am looking at the transmission and maybe trying to swap it out with very little mechanic experience (some knowledge though)

Thank you !

Hi LePucco,

Welcome to the Jaguar Forums. It's great to have you with us.

You have posted the same question in two different forums, one for the X308, and this one for the X350. These models have completely different transmissions, and since you haven't told us the year and model of your Jaguar, we don't know how to respond.

The first thing for you to do is to visit the New Member Area - Intro a MUST, and post a required introduction so we can learn something about you and your Jaguar and give you a proper welcome. Then, read this thread:

*New Members - a MUST read if you have just signed up*

Once you have done those things, please start your own new thread in the correct forum for your model, tell us the year and model of your Jaguar, and describe the symptoms or malfunctions it is exhibiting. It is quite possible that your transmission does not need to be removed at all. But we can't help you without more details. X308 is the Jaguar factory project code for the XJ8 from 1997 to 2003. X350 and X358 are the codes for the XJ8 from 2004 to 2009.

Cheers,

Don
