Hey everyone,
I have a 2003 2-type 3.0 and it seems to be having some transmission issues. The symptoms are as follows. It give a clunk when you put the car in to drive or reverse. It also won't shift out of 1st gear. There are a few error codes from ABS and Gearbox fault. Also on the computer the codes are p0701 and p0731

Any advice?

 

Welcome to the forum Paulantent.
Please post an intro in the new members section when you can.

First step is to make sure the battery is fully charged, then I'd try and trace the ABS faults first they may be upsetting the tranny.

 

 

+1 on that. More details on your P0701 and P0731 codes here:

Note how P0701 is related to a DSC (Dynamic Stability Control) fault. The manual says to look for related DSC fault codes. Keep in mind most scanners can't read Jaguar-specific codes, just the generic emissions codes that all newer cars use. Could be you've got a DSC fault due to the rear wheel bearing issue, but your scanner can't tell you.

Two options:

1) Replace that suspect wheel bearing and see if P0701 clears itself.

2) Take the car to a Jaguar specialist shop (dealer or independent) that has a scanner that can read all the codes, not just the generic ones.

Your call, but since you know you have to replace that wheel bearing assembly, I'd fix the known problem first. You've got to replace it anyway, so it's not wasted money if no help with the other stuff.

 

Norri, thank you for the reply and help! I will check the battery to make sure it is fully charged. May I ask how the ABS might affect the trans?

 

Do you think a TCM module might be the issue?

 

No.

Best bet is follow the advice already given.

 

Agreed, no

 

The ABS sensor provides information to the transmission if that's info is not good the trans will get confused, the wheel bearing may be causing the ABS fault.
Do the easy stuff first.

 

Update, the car is now running normal! Transmission is changing gears.
More info to follow as the car is being used by one of the guys that work for me and as soon as I get the details I will post.
Thanks again for the comments and help.
