ATF To Replace or to Flush
Posted: 24 May 2018 18:52
Hi All
I started another topic 2 days back for service components and I think I have my shopping basket complete. I now have to decide if I am just going to do regular maintenance ATF change or if I am going to flush. I pulled a little sample of ATF as can be seen in attached image. It is basically caramel in colour with a slight red tinge to it. I am not seeing any particles in the sample so other that the discoloration the fluid appears clean and the smell is what I expect from oil. It does not smell like burn.
I like the idea of a flush so I know it is all good stuff in there but there appears to be many mixed opinions on the topic. Many people says flushing the gearbox can cause damage and the other lot says the fluid flush just exposes a pre-exisiting condition. Interpret it as you wish. Drive it till you can afford fixing or expose the problem rather than get surprised on a long trip..........
Anyway. It is a highly contested topic which does not make my desiscion any easier unfortunatly. So I am putting it out for opinions.
Based on the current state of the oil:
1. Do I flush?
2. Do I do normal 40%- 60% change
3 Do I do normal change over 2 or 3 fairly closely placed intervals.
Also what is the opinion on dropping the pan and cleaning/replacing the ATF filter?
