Slipping Auto Box (previa)

[keithjones]

During the last cold snap my Previa was reluctant to pull away from cold starts - as if the auto box was 'slipping'. It happened again yesterday (when the weather wasn't that cold) the car almost crawled away. The problem disappears when everything has 'warmed up'. Any ideas? Is this a sign of some big bills on the way?

Maybe your fluid needs changing (ohhh errr) ....in your transmission ? Just a thought.

Check fluid level is correct when warm. If you have an owners manual go with the instructions otherwise try this. Drive for 10-15 miles. With engine still runing move the gear selector through all selections(with handbrake+footbrake applied). Then move selector back to park, LEAVE ENGINE RUNNING. Remove autobox dipstick and wipe then reinsert. remove and check fluid is between the notches for the hot reading. If low add a little at a time till near the top of the 'hot' notch. DO NOT OVERFILL. This can cause the fluid to foam up and the selector valves will not funcition properly.

If it is overfull drain excess off.

The only other options apart from those in other replys is to have the gearbox checked over by an autobox service centre.
