Sonnax Trim valve and spring kit

[rcr1978]

I was looking through Sonnax's stuff and found this https://www.sonnax.com/parts/2121-trim-valve-spring-kit

Sure looks similar to the transgo kit except the little springs and check balls, unless they are in the valve already crimped in so they don't come out, instructions even have you drill the separator plate. I was more interested in the F trim spring just curious if anyone has tried these? The reamers are expensive for them though. I know the JR is the tried and true way just curious is all

you know there is this guy on here named Mike who had specially designed springs to go in those spots .

Won't do much. Any increase of pressure to the clutches will be nixed by the TCM. That's why Transgo uses the check balls to fool the TCM so it doesn't react. The F trim spring doesn't do squat. Increased pressure to the TCC is done by modding the converter flow valve, not the F trim valve.
Just remember if you use this kit and don't like it; you need a new valve body. No going back. Trying to use the Transgo valves after boring the valve body will result into the most violent shift you have ever felt.

That's what I was looking for Some of there stuff is not bad the F spring I've seen worn a few times though maybe that may be better but I will stick with OEM.
