Jeep Grand Cherokee auto gearbox problem - jon01
Help!
I have A 97 Grand Cherokee which has been with A chrysler dealership all day and they cannot find A fault.
Autobox will not go into top gear.
Please does any one have any suggestions???
Many thanks.

Find a local auto specialist. Most main dealers haven't a clue about auto boxes, they sub the work out to ...... a local auto specialist.

Some Ford autoboxes rely on a speed sensor to initiate the change into top. The gears within the speed sensor can break, hence no top gear. Alternatively, the signal wires to/from the speed sensor can break.

Which has nothing to do with a Chrysler box.

Many thanks for your suggestions, will give that A try.
Vehicle has also been with A mobile mechanic for A while and computer diagnostics have been tried,
all to no avail!
