Ok, an update on my 65RFE Sonnax valve body installation for anyone watching or cares. I just got through with installing the 2nd Sonnax valve body this time with the white plug solenoid CHR146. I did a quick learn and took it on a test drive and it is doing as it should. I didn't do any hard runs, just letting it shift as it wants to. First impression is I really think I can feel better shifts even though I didn't feel like I had an issue to start with. We all know how our heads wants to feel an improvement but right now I am very happy with it. I will be able to let you know more as I drive it more. If I can give any advice if anyone wants to do this is to get it with the whole assembly "with the white solenoid" even tho Sonnax said it will work with all 3 color solenoid plugs "I" will never change another one with using my solenoid on their valve body! Chance it if you want but I don't have to learn anything twice
