Transmission failsafe prog

[Daddymac]

My 2003 x5d sport is going into trans failsafe mode quite regularly now. There is a sudden clunk and jolt when you try to put your foot down on the accelerator as if it is missing a gear or won't drop down a gear. Can anyone help or suggest a reliable specialist in the Uttoxeter area to take it to.

Cheers, Dave.

By your description the issue could be caused by a number of faults, easy ones first. Old dirty fluids, Low transmission fluids (leak somewhere), failing Torque converter, Valve body issues.

My guess is that as you have been having the issues for some time box has internal damage and will require a rebuild, sorry.

You really need to find an Auto Transmission Specialist in your area (sorry I am in Sussex) who will be able to investigate the problem by reading the Transmission codes. I have seen rebuild costs as low as £1200 and as high as £2000+ (BMW will try a new trans at £4k+) My belief is the Transmissions are rarely serviced yet the manufacturers (Mine is ZF) advise Fluid changes at 80 to 100k KM about 60k miles, don't know how many miles yours has covered but probably more than that?
