IMO, no reason to do more than DnF with the VTM-4, you’re getting maybe 95% maybe more when draining the VTM.Today, on Father's Day I bonded with my newly adopted G1. I got mechanical with it and did my first transfusion in trying to set my baseline for maintenance @ 193,788 km.
Well, more accurately I did my first drain and fill DNF of the Transmission fluid. The previous owner said one was done a while ago. I thought I would do the recommended 4 to make sure there is predominantly DW-1 in the transmission.
Photo of new fluid to what came out - I plan on posting photos of all 5 samples when done.

In the grand scheme of things, by the time I bought everything needed it would have been cheaper to have the garage do it. OTOH I will save on everything else maintenance wise later on. I have not done mechanical stuff in a while. It was sort of nice to get back into it. I plan on doing 3 more DNF's, 2 VTM-4 and 1 transfer case over the next month or so on alternating weekends.
The hardest part of the job was continually checking the fluid level after filling. I went with the 3.1 liters in the service manual took it around the block & checked it hot. Added 100 ml at a time not wanting to go over - driving & checking each time. As others have said it does take 3.5 liters to do a DNF.
Point taken, thanks for the suggestion.IMO, no reason to do more than DnF with the VTM-4, you’re getting maybe 95% maybe more when draining the VTM.
When I changed my coolant, the old coolant with 180K+ miles on it looked like the one in the middle (from your pictures). You are telling me that your old coolant looked brown? I dont believe I have seen it before.
It might have been the lighting. My old eyes see a darker grey like oxidized aluminum with maybe a hint of purple. After making sure the containers had similar volumes, I took them outside in the northern shade and rephotographed from directly above, once again on a white background. I then colour enhanced the shot to the white background. How does this look now?You are telling me that your old coolant looked brown? I dont believe I have seen it before.
Reading an older thread that recently resurfaced, I noticed that @Carsmak mentioned seeing purple in his coolant during a change.My old eyes see a darker grey like oxidized aluminum with maybe a hint of purple.
I may not be the only one.I know this much my coolant looked more of a purple than the blue the Type 2 Acura/Honda typically was.
