Hi,
I'm planning on doing a drain & fill of the transmission's on my car (S80) & my Dad's V70 (both P3 shape). Both cars require JWS3309 fluid, which I'm aware of. Would you recommend doing a drain, filling it back up & driving for say 1,000 miles or so before repeating the process. Or, would you just advise draining & filling all on the same day until the fluid becomes its original colour? I understand that you can only get around 3L out of the transmission at a time via the sump, due to fluid being trapped within the internals. I'm going to get one of the 20L drums on Ebay made my Mannol, as that'll do both vehicles.

500 miles will give you a full mix. 15 miles will give you a 99.99% mix.... it’s more important to cycle through all the gears a good few times than sit on the motorway for a while.

I'd just like to clarify what I meant - it's more important to cycle through the all the gears several times whilst on a good drive, not sat parked on the drive...

On the TF80 transmission, worthwhile to also check you have the latest software installed.

Lets say the existing fluid in the transmission was very dirty. How many times would you need to repeat the process to get the fluid clean would you say? This would be based on doing drain & fills over a period of time with 200-500 miles in between each fluid change. Also, would it be okay to reuse the rubber washers/o-rings that go on the transmission drain plug whilst doing these drain & fills, but replacing them with new ones on the final drain & fill when the fluid is clean? Otherwise, it means replacing the o-rings every single drain & fill... seems a bit of a waste of o-rings when only doing 200 miles or so in between changes.

Didn't the/an E European guy publish a video plus bottles which of the 5 (IIRC) changes he did, showing the change in colour. It's out there somewhere
ETA Yep, he did, and it is https://youtu.be/EAb9p8Wph-M Last edited by Bonefishblues; Feb 23rd, 2021 at 17:04. |

I'm not critizing the video, as its very clear & well put together. I suppose I'm offering my opinion, or it may be considered constructive criticism. The chap in the video isn't bringing the car for a long drive in between the drain & fills. Even if he didn't go for a long drive on the day he drained the fluid for the first time, he could have done a few hundred miles over a period of time before draining it again & then repeated the process with a few hundred miles in between each drain/fill until the fluid was clean. Pouring fluid into the transmission, cycling through the gears whilst the car is still on axle stands & draining it after a few minutes seems pointless to me.

The fluid will not circulate the box you do need to drive a decent distance. |
