Hi Jules - sorry about that - it had done 110,000 km (68,000 miles). Of which about 70% was very short distance town driving. Not Good.

Seen a lot of materials lately that will give as equivalent the T-WS (JWS3324) with Dexron VI.
This is why a combination of 50/50 of ATF/acetone is better than any super penetrant oils on the market. |

Thanks Alex. Being in the Aircraft Engineering trade, I came to more-or-less your conclusion -you have just spelt it out very clearly and understandably with great substantiation.

Thank you for the advice Alex. I'll invest in some car ramps and do a regular drain&fill. If I notice even a small improvement in gear-shift smoothness I'll consider it money well spent. It can be a little lumpy when fully warmed up (not excessive but it is noticeable vs cold... oddly) so I'm intrigued to see the result. |

ATF expands a lot as it warms so checking the level has to be done near a set temp. Replacing a measured volume of hot ATF will require a smaller volume of cold ATF. It used to be easy when autoboxes had dipsticks but now its a PITA. However once youve satisfied yourself that the gearbox is filled to the correct level you could carry out serial "dump and fills" by weighing the oil drained and replacing with same weight of cold ATF. This may save a bit of time if you doing a series of "dump & fills". You may need to sneak the wife's cooking scales out of the house to do this though. I calculate that starting with a total of 7L of old ATF in the gearbox, sequential 3L "dump & fill"s will remove 43%, 67%, 81%, 89% and 94% of the original old ATF assuming good mixing of old and new ATF between changes. So 3 "dump & fills"will remove the vast majority of the old ATF and 5 changes will remove nearly all of it Jules |

How can you manage to remove 3.6 liters when myself and many others, after a previous filling with a proper level check, couldn't manage to drain more than 3 liters ?...
