AU auto thumping

Hi dudes, I have a small prob with my auto, and want to know if anyone else has experienced this. Most of the time changing seems normal, but at times it's a bit slow and seems to hesitate before changing. Also sometimes when backing off the horses and slowing to corner, as you straighten up and increase horses the auto thumps in the rear. Ford told me "she's alright mate, and drive most of the time in economy mode" I rang an auto specialist and he said that you can't adjust the tranny's in any way! So what on earth do I do? Thanks

Re: AU auto thumping

More than likely it will be a faulty S-5 solenoid.
These do play up on the odd occasion.
This solenoid controls the line pressure in the trans, therefore will cause soft or hard changes which is what your experiencing.
Also i'd say dont go to the trans place you called, because the AU's came out with an adjustable S-5 solenoid from the factory - the line pressure CAN be adjusted.

Hey thanks bro, In view of the fact that my car is 5.5 years old, would I be better off just replacing the solenoid you mention, or get it sussed first? Any idea what they are worth? Thanks dude.

Re: AU auto thumping

I'd say get the trans serviced 1st - full fluid flush etc should cost around $130ish, and see how it goes after that.
If it still plays up, then investigate futher, It could also be caused by one of the other solenoids too, The s-5 itself costs around $300.

Also, i'd suggest NOT driving it in econ mode all the time, but in Power (or Normal) mode.
Econ mode makes the trans change gears a lot earlier, therefore it creates more heat and wear within the auto (torque converter slipping more)
Power(normal) / Econ modes only change gear shift points, not actual engine power output.
